3dMDbody System Series

The human body in motion is the ultimate real-world data challenge… capturing and reconstructing the full anatomical complexity of posture, movement, and dynamic shape change across diverse subject populations with near ground truth 3D-shape accuracy. The 3dMDbody system series was purpose-built for exactly that challenge.

Capturing 360-degree full body coverage dynamically in 3D/4D, the 3dMDbody delivers real-world dense-surface body data at the anatomical fidelity that the most demanding applications require. Unlike sparse marker motion capture systems and parametric model-dependent approaches whose output is only as accurate as the 3D model they started with, 3dMDbody captures and reconstructs the actual dense-surface 3D shape of every subject… in motion, with sub-millimeter accuracy, and without markers, suits, or synthetic inference. In healthcare, 3dMDbody data supports clinical teams in monitoring and measuring postural, morphological, and gait change throughout treatment cycles… from scoliosis and spinal deformity through to orthopedic assessment, lymphedema, and body composition analysis. Beyond healthcare, the same near ground truth full 3dMDbody geometry powers AI and Machine Learning body model development and Computer Vision training such as the SMPL model by the world-class 3dMD customer team at Max Planck Institute for Intelligent Systems, Perceiving Systems, in Tübingen… human factors, size and fit, and ergonomic design across performance sportswear, military uniforms, protective equipment, and high-performance vehicle and workspace environments… wearable tech calibration across diverse body types… and real-world 3D/4D digital human body development for humanoid robotics training and XR environments.

Region of Interest:	Provides 360-degree full body coverage. Captures a range of postures, poses, actions, gestures, etc. dynamically in 3D over a period of time (4D).
Capture Speed Options (3D frames per second):	1-10fps, 1-30fps, 1-60fps, or 1-120fps with high precision 3D shape information generated for each frame, regardless of capture speed. Run system in record, burst, or single snap mode.
3D Image Reconstruction Technique:	Sophisticated software-driven triangulation technique called Active Stereo Photogrammetry.
3D Image Reconstruction per Frame:	Automatic generation of an individual 3dMD image from all stereo viewpoints within the system to create a single continuous 3D point cloud or textured mesh (no manual stitching or registration needed per frame).
3D Shape Accuracy:	Delivers ‘near ground truth’, high-precision 3D dense surface images with a linear accuracy range of 0.7mm or better… also known as first generation, Real-World data.
Output Options:	A progressive sequence of 3dMD images from a recording, a short progressive sequence of 3dMD images from a burst, and a single 3dMD image from a single snap.
Output. File Formats Supported:	obj, stl, ply, gltf, glb, x3d, 3mf, as well as all other industry-standard open formats for use in downstream 3dMD and third-party software.
Baseline 3dMDbody System Configuration:	3dMDbody10 System captures a standard A-pose and similar poses for average-sized people. Incorporates optics-based technology with ten (10) Modular Camera Units (MCUs) of 30 machine vision cameras synchronized with a robust LED lighting system.
Specialized 3dMDbody System Configurations:	Depending on requirements [types of poses, actions, gestures, interactions; areas of interest; etc.], 3dMD can configure the 3dMDbody System to include additional MCUs to accommodate these requirements. 3dMDbody system configurations range from the baseline of 10 MCUs\|30 machine vision cameras to 30+ MCUs\|90+ machine vision cameras.
Camera Technology:	Industrial-grade Machine Vision camera technology.
Eye-Safe Lighting:	Safe and comfortable subject illumination within visible white light (100% LED lighting) which is necessary for prolonged sessions with subjects – no use of infrared (IR) or near Infrared (NIR) light waves.
3dMD Image(s) Downstream:	Either 1) select the most optimal 3dMD images from the sequence [e.g. an interaction, gesture, finger articulation, etc.] OR 2) import the entire 3dMD image sequence into the downstream 3dMD, third-party, or in-house software to transition a project from 2D video, sparse-3D, or static-3D to a dynamic-3D/4D dense-surface mobility paradigm.
Environment:	Utilized in normal R&D lab, clinical, and studio environments.
Safety:	International UL and CE safety certification.
Upgrade Path to:	Any specialized 3dMDbody System (add 2-20+ MCUs).
Third-Party Device Synchronization:	For advanced customer teams who qualify, 3dMD offers a range of 3dMDsync Unit options – e.g. Synchronization Output only, Synchronization Output and Input, and Synchronization Output and Input with Frame Level timestamping functionality.
Techniques and Technologies NOT Used by 3dMD:	To confirm, 3dMD does NOT use lasers, depth sensor cameras, pro/consumer cameras, or infrared (IR)/near Infrared (NIR) light waves within its systems. 3dMD does NOT use a ‘structured light’ capture/reconstruction technique.
