Post processing - Recognizing that the ML and Computer Vision algorithms can fail - YES, we can be wrong. Identifying body landmarks is not a perfect science. It’s a mix of anthropology, metrology, linguistics, geometry etc. With 200+ staff years of experience with developing this solution and talking to a number of people all over the globe, we have realized that we may still miss a certain landmark or measurement. The definition of certain measurements vary and are still debated. The input avatars may not be perfect. These are external factors that affect the measurement accuracy. There can never be an Artificial Intelligent system that we will be able to build that will be faultless. So one of the most important characteristics of an autonomous system is to be able to recognize its own mistakes. Talk about BEING HUMAN. - Gentry Lee on Limit of AI. https://www.youtube.com/watch?v=BkFBz4I5AL8   There are internal or platform reasons too. It is a complex system. Since we use Machine Learning in tandem with Computational and Geometric algorithms, the challenge for us is to identify and isolate the cases where we might have missed our landmarks or when we may not have gotten accurate results.  It could be because the scan pose is different from the ones we designed for or the body shape is different or the platform we host on had an issue with the floating points.    We may not be 100% right all the time, but we still have to make our system more reliable. The way that can be achieved is by knowing when we might have failed. We can validate the output of the system and filter out the anomalies to make it more dependable. 3D Measure Up platform has an alternate system to verify each measurement value for each request. The verification system discards measurements that are surely wrong. One of the validations is based on relative measurements, obvious comparisons like a. Foot length should be greater than Foot width b. Calf girth should be greater than minimum leg girth c. Hip  girth measurement should be greater than thigh girth   Similar validation can be done by checking the position of a measurement. For example a. Level of the calf girth is between the knee and ankle b. Foot waist is between Foot Instep and Foot Ball c. Waist is always between the Chest and Hip.     The other validations include checking the shape of the girth  We check the starting point of the girth is the same as the end point. For example  a. Whether the girth closes properly Incomplete girths could be caused due mesh defects such as self intersecting meshes.   But then 3D Measure Up can do this in a generic way that is common to all use cases. Another layer of validation by the developer or the end user can certainly be added to improve the reliability. 3D Measure Up API and WebAPP provides an option to export the result as a 3D HTML file that renders the avatar and the measurements in 3D in any standard browser. This 3D rendering is a great tool for visually verification of the output by the end user or the expert viz. Fashion designer, doctor or anthropometrist.    Click here to signup for a free trial of A body measurement software, or contact us at 3dmeasureup@prototechsolutions.com Know more about the Measurement of human body parts and 3d body measurement software Verification of measurement system Avatar 3d view Measurements for niche applications Body Measurement Technology Contact us: 3dmeasureup@prototechsolutions.com 3D Measure Up

Take Measurements And Share Them. Not Just The Spreadsheet, But In Full 3D You would expect a 3D Measurement API to be a simple bland affair – you pass the avatar and get the measurements in an array or a spreadsheet which in turn you pass it on to your customer. Well, it doesn’t have to be. You can make it very very interesting. The 3D Measure Up Web API now has an option to return a full 3D view of the avatar with annotated measurements. This is returned as a normal HTML (.html) file which can be viewed in any browser or embedded in any web page and does not require internet connection. Yes, it does not require any internet connection because none of the data including the avatar and the measurements are on our server – it’s all included in the HTML file itself which you have full control over. This feature extends the current measure API by adding an additional parameter “exportHTML” to the request body. The expor tHTML is false by default. When set true, the metrics response contains an attribute “downloadHTMLURL”. The download URL is a signed URL. It is valid for 1 hour. The application can download the self contained HTML file and load it in the browser. Since the HTML is self sufficient, it can be loaded from a local drive without the need of a web server.

Measurements of the Thoracic Region This blog illustrates the different chest measurements extracted from a 3D scan. At present, a full body scan is required for extracting these measurements. Chest measurements are crucial for making patterns for suits, ladies garments, t-shirts, shirts and jackets, for men and women. They also play an important role in size and fit recommendations. The shape of the body can be determined by accurately measuring the torso.  To enable the designer to make accurate cloth patterns, 3D Measure Up offers more than 50 measurements in the Thoracic region (from the Neck to the Hip) that are horizontal, aligned to the skeleton, contoured and measured by tape.

What can 3D Measure Up do for you? Your vacuum, dishes, laundry…? Not yet, but for now... 3D Measure Up helps you accurately identify landmarks on objects and provides hundreds of measurement parameters viz. distances, girths, heights, surface areas, volumes etc. We are primarily set to work on 3D scans of the human body (full or partial), but the core technology is extensible to any object or shape. We have taken some very special measures using a combination of computational, geometrical, and machine learning algorithms to give you very accurate results. 3D Measure Up extracts about 130+ unique measurements from a 3D scan of a human body. The measurements can be : 1. Landmark points 2. Surface Length 3. Straight Lengths 4. Girths or Circumferences 5. Free-Fall lengths 6. Custom Measurements Landmark Points These are clearly defined points on the body that can be used for defining anthropometric measurements. They are described by their level from the ground and position in the 3D World. Some of the common landmarks are illustrated below:                                      a. Center Neck Point                                                                                          b. Left Side Neck Point.   c. Crotch Point Surface Length Surface length is the distance between two points on the body measured along the surface of the body.                                                                                                  d. Back Neck Point to Knee Length                                                              e. Outer Arm length Straight Length Straight length is the straight line distance between two points on the body. It ignores the body shape and surface. They are useful for applications like prosthetics. Straight distance between the chin and base of the neck (f. Straight Length demonstrating the distance between chin and the base point of the neck.)                                                                        f. Straight distances along the arm                                          g. Straight distance between the shoulder and wrist. Griths or Circumferences Girths are circumference measures at standard anatomical sites around the body, measured with a tape measure. Girth measurements can be used in determining body size and composition, and to monitor changes in these parameters.                                     h. Girth at neck end.                                                                           i. Chest Girth. j. Waist Girth Difference between Parallel to Ground and Aligned to the Skeleton Girths The girth axis may be aligned to the skeleton of the body or it may be perpendicular to the floor. Girths on the arms, legs, and feet are always aligned to the skeleton. 3D Measure Up offers both girths on the head, neck, and torso regions. (k. Girth measurement aligned to the body/skeleton.)                                      k. Girths Aligned to the skeleton                                                  l. Girths Parallel to the Ground/Floor Difference between Tape and Contoured Girth measurements A tape measure is using tape, these are typically used for regular apparel applications. Contoured is along the path on the surface of the body. These are typically used for functional clothing. The images below show both contoured and tape girth measurements for the chest:         m. Contoured Chest Girth         n. Tape Measure for Chest Girth The following table shows the different types of girth measurements along the human torso, their difference in measured values, and the way the measurement is extracted. The figures in red are measured values for the 3D Measure Up’s demo model. Free-Fall lengths Free-Fall length is the length of the trajectory followed by a dewdrop starting at a point on the body and flowing down the body by effect of gravity. This is useful when we like to do such a measurement for cloth which involves partial measurement on the body surface and partially hanging down freely. Back Neck point to the ground                                                        From a point on the waist to the ground                                                                                       o. Free fall length Custom or User-defined measurements 3D Measure Up attempts to cover most use cases. But there are some measurements that have not been incorporated yet. Some measurements could be proprietary to the user or organization. To accommodate such scenarios 3D Measure Up offers tools to

Perfect | Accurate Automatic body Measurements Requirements for Accurate measurements 3D Measure Up makes the best effort to identify landmarks from scans of people in different poses and scans of varying quality. Having said that, for accurate and reliable measurements required for MTM or bespoke applications, we recommend the following: 1. Mesh Quality: A good quality mesh received from the scanner will yield better results. The expected mesh has the following qualities: a) It is a single, triangular mesh. b) It has watertight mesh i.e. no holes. c) It has no stray triangles or disjoint meshes. d)  It has no broken mesh or self-intersecting meshes. These occur usually on parts of the body with folds. Eg. armpits, crotch, elbows, back of the knee, the web between the fingers. e)  It has no platform below the feet, attached to the scan.         f)  Avoid fused body parts.              2. Pose: Though 3D Measure Up can handle any pose, the 'A' pose is ideal - the model standing with arms straight and pointing downwards. Fig: Model standing with arms straight and pointing downwards. 3. Alignment: A perfectly aligned model (no leans, no stoops) with '+Y' along the height of the person is ideal. Having said that, 3D Measure Up has inbuilt capability to correct alignment. Fig: Perfectly aligned model. 4. Mesh Size: Having said that, it is our observation that mesh size between 7MB to 12MB yields enough precision for most of the general applications. Beyond 12MB, the impact on performance may not be worth the increase in precision. Though you may want to validate this specifically for your requirements. Fig: Mesh size between 7MB to 12MB. 5. Clothing, hair styling, and other accessories: The clothes should be tight-fitting to get accurate measurements. Accessories straying out of the body surface or altering profile are best avoided. Hair should ideally be tied and tucked neatly as close as possible to the head. Fig: Model for clothing, hair styling & other accessories.

Body scan at home. Get your 3D avatar using a smartphone. Get 100+ measurements! fig: body measurements using phone camera The pandemic has forced everyone to remain indoors. While we still need to buy things for a living. Most of us are now used to re-ordering almost everything viz. Grocery, Meals, Kitchenware, and most importantly apparel. The biggest pain with apparel though is the hit and miss game that we have to play with the fitting. We end up returning more than half of the clothes, shoes, and other fashion items that we buy online. Why so? Most of it because it is not the right fit. And we know - returns are not pleasant at all. But finally, here’s some help from the technology. Handheld hardware scanners are on the rise and getting into the hands of more and more people - New generation Apple devices such as iPad Pro 12 already have a LiDAR sensor which does a decent job of capturing the world in 3D.  On the software side, there is extensive research and development done on converting 2D photos to 3D scans. The application of computer vision, image processing, and machine learning has greatly enhanced the fidelity of this conversion. In this blog, we demonstrate how to use the iPhone 12 Lidar scanner to get a 3D scan of a person and use it to extract human body measurements using ProtoTech’s 3D Measure Up. We used the 3D Scanner App and iPhone applications to get the scan of the person. It can be downloaded from this link: 3D Scanner App: https://apps.apple.com/us/app/3d-scanner-app/id1419913995   Configuring the app before taking the scan We set the following parameters in 3D Scanner App before starting the scanning process: 1. Resolution:- 9mm  2. Masking:- Person 3. Range:- 0.5 m 4. Confidence:- High   Steps or recommendation for scanning a human body: Two persons are involved in the scanning process. One who is getting scanned and another person to do the scan. Instructions for the person being scanned: 1. Stand in an A posture ie. with feet about 30 cm apart and the arms are way from the body. See the image below: 2. Stands still during the scanning. It takes about 3 to 4 minutes at maximum to generate the scan.   Instructions for the person generating the scan: 1. Holds the iPhone firmly such that the phone is vertical ie. at a 90-degree angle with the ground at all the time. This is necessary for accurate mapping of the body. 2. Keep the iPhone at a fixed height and move around the person to be scanned in a circle and the person being scanned is standing at the center. 3. It is recommended to perform the scanning more than once at the same height. 4. Start scanning at a level of height of the person and gradually decrease the height of the scan after completing one or two circular rounds at the same height. 5. Repeat this till you reach the ground and the entire body is covered. 6. Once the scan is completed. Smoothen the scan from available options in-app.     Export the OBJ/STL file There are multiple options available to share the scan. We exported the OBJ file through Email. There is also an option to store the scan in the device storage.    Using 3D Measure Up to extract measurements from the scan Transfer the scan obj file to your desktop.  Load it in 3D Measure Up to extract the measurements.

Remove the floor/platform at the bottom of the scanned model A common problem with scanned models is the platform at the base of the model. The platform causes inaccuracies in the measurements and alignment. This blog enlists the steps to remove the platform at the base of the scanned model using Autodesk Meshmixer. Mesh Mixer is a free software for working with triangular meshes. You can read more about Meshmixer and download it from www.meshmixer.com. Once you have installed Meshmixer on your machine. Steps to remove the floor at the bottom of the scanned mesh: Right-click on the file name of the scan file. Select Open with and then Mesh mixer. After the model is loaded, Align the model such that it is facing the screen. From the left control bar, select Edit. A menu with edit operations will popup. Select 'Plane cut'. A Plane Cut dialog will popup and a control widget will float over the model. On the control, widget find a (W) icon. Click on it. The blue and red arrows will flip. Click and drag the Red triangle between the green and blue arrows. This moves the Cut Plane. Move the cut plane down such that it matches the floor level. Release the mouse button when the Cut plane matches the floor level. The floor mesh is removed and the mesh is closed at bottom of the foot. Click on the export button to save the model on the local drive. Meshmixer cut model,3d scan editing software,Mesh healer Autodesk Meshmixer,Measurement on 3d scanned model,Healing scanned model.
