Q: What is ProtoTech 3D Measure Up?

ProtoTech 3D Measure Up is a service that makes it easy to add powerful 3D measurement and analysis to your applications. 3D Measure Up lets you easily build powerful applications to identify and measure many landmarks on a 3D scan of a human body.
3D Measure Up is an anthropometric measurement service that detects various landmarks or features of a human body such as ankle, knee, tip of nose, shoulder point etc. It also allows you to measure various parameters of these landmarks e.g. position of mid-thigh from the ground, girth of biceps, waist, bust, volume of torso etc. 3D Measure Up is based on the proven, highly scalable, machine learning technology developed by ProtoTech’s 3D geometry, graphics and visualization experts.
3D Measure Up uses various algorithms and technologies based on mathematics, geometry, human anthropology, deep neural network models etc. to detect and label landmarks and features in your 3D scan. We are continually adding new landmarks to the service. With ProtoTech 3D Measure Up, you only pay for the 3D scans that you analyze and/or store.

Q: What is deep learning?

Deep learning is a sub-field of Machine Learning and a significant branch of Artificial Intelligence. It aims to infer high-level abstractions from raw data by using a deep graph with multiple processing layers composed of multiple linear and non-linear transformations. Deep learning is loosely based on models of information processing and communication in the brain. Deep learning replaces handcrafted features with ones learned from very large amounts of annotated data. Learning occurs by iteratively estimating hundreds of thousands of parameters in the deep graph with efficient algorithms.
Several deep learning architectures such as convolutional deep neural networks (CNNs), and recurrent neural networks have been applied to computer vision, speech recognition, natural language processing, and audio recognition to produce state-of-the-art results on various tasks.
ProtoTech is one of the pioneering companies to apply deep learning principles to 3D data. ProtoTech 3D Measure Up service use deep learning to understand 3D body scans and recognize features.

Q: Do I need any deep learning expertise to use ProtoTech 3D Measure Up?

No. With ProtoTech 3D Measure Up , you don’t have to build, maintain or upgrade deep learning pipelines.
To achieve accurate results on complex 3D scans such as feature detection, mesh processing, point cloud manipulations, geometry computations deep learning systems need to be tuned properly and trained with massive amounts of labeled ground truth data. Sourcing, cleaning, and labeling data accurately is a time-consuming and expensive task. Moreover, training a deep neural network is computationally expensive and often requires custom hardware built using Graphics Processing Units (GPU).
ProtoTech 3D Measure Up is fully managed and comes pre-trained for 3D body scan recognition and measurement tasks, so that you don’t have invest your time and resources on creating a deep learning pipeline. ProtoTech 3D Measure Up continues to improve the accuracy of its models by building upon the latest research and sourcing new training data. This allows you to focus on high-value application design and development.

Q. What APIs does ProtoTech 3D Measure Up offer?

ProtoTech 3D Measure Up offers APIs to detect landmarks and features of a 3D body scan, measure heights, measure straight distances, measure distances along the body surface, measure girths, compute volumes. For details, please refer to the ProtoTech 3D Measure Up API Reference.

Q: What 3D scan formats does ProtoTech 3D Measure Up support?

ProtoTech 3D Measure Up currently supports the OBJ format.You can submit 3D scan either as an S3 object or HTTP URL such as Google Drive or Dropbox file URL. ProtoTech 3D Measure Up can analyze 3D scans stored in ProtoTech S3 buckets or Customer’s S3 buckets. The 3D scan must be in OBJ format. If you would like us to support a different format, you can contact us here.

Q: What file sizes can I use with ProtoTech 3D Measure Up?

ProtoTech 3D Measure Up supports 3D scan file sizes up to 20MB.

Q: How does scan resolution affect the quality of ProtoTech 3D Measure Up API results ?

ProtoTech 3D Measure Up works across a wide range of 3D body scan resolutions. The accuracy of location of the landmarks and it’s measure increases with the increase in scan resolution. This is obvious because you have more points and thus more details in high resolution scans. At the same time, it is important to remember that there is a limit on the file size that can be processed. Further, the higher the resolution, more time it will take to process the scan for identification and measurement. For most of the applications, scans with file size up to 20 MB should be good enough.

Q. How small can a 3D scan can be for ProtoTech 3D Measure Up to identify and measure it?

There is no such condition. You are free to provide very small sized scans as long as it contains enough details to visibly identify the landmarks (by a human being) and the precision of the measurement obtained is acceptable to you.

Q: What else can affect the quality of the ProtoTech 3D Measure Up APIs ?

Besides scan resolution, other factors that can impact are
* Quality of mesh: The mesh should be single and ideally be water tight with no gaps.
* Pose: The ideal pose for scan is standing with arms straight and pointing downwards (‘A’ pose).
* Clothing and other accessories: The clothes should tight fitting to get accurate measurements. Accessories straying out of body surface or altering profile is best avoided.
* Hair style and other accessories: Hair should ideally be tied and tucked neatly as close as possible to the head.
* Quality of scan: The scan should be clear and isolated. There should be no stray objects or points in the scan.

Q: What is the preferred scan that is suitable for ProtoTech 3D Measure Up APIs?

This API works best with consumer and professional scans. Ideally position is standing, looking straight, arms out-stretched and pointing downwards – what is also known as ‘A’ pose. The ideal outfit is minimal and body hugging. If the person has long hair, then it should be tied and tucked such that it doesn’t interfere with the measurement. Applications that are sensitive to false alarms are advised to discard outputs with confidence score below a selected (application-specific) confidence score. Please contact our technical support for details on accessing ‘confidence score’

Q: What file sizes can I use with ProtoTech 3D Measure Up?
