Temporal-3dMD Systems (4D)

As a pioneer in the development of high-precision 3D surface capture technology and anatomical 3D surface analysis software, 3dMD has taken the next step in innovation to offer its latest generation 3dMDdynamic temporal-based (4D) systems and 3dMDtempus dense surface tracking software to support a quantifiable understanding of true anatomical movement and function, regardless of how obvious or subtle.To record the most natural performance from a subject, the 3dMDdynamic System incorporates a non-intrusive, LED-based lighting system that promotes eye-safety and subject comfort; eliminates the need for any special surface makeup or preparation; and minimizes distraction stimuli. Never before has there been an opportunity to objectively quantify the anatomical movement and expression of adults, infants, and even restless children, of all skin tones in a natural, non-obtrusive environment. Each 3dMD frame is rendered separately and maintains a consistent accuracy to ensure no jitter on the resultant 3D soft tissue models. Elimination of jitter allows a smooth sequential playback with integrity building a platform for highly sophisticated dense motion analysis of the resultant surface deformations.

3dMDtempus Surface Tracking Software

In addition to providing a playback sequence of individual 3dMD frames each with full integrity, the 3dMDtempus software enables both discrete and ultra-dense analysis techniques of the subject’s skin dynamics with posture, pose, and functional movement. The user simply defines the regions of interest, or xyz points, to track through the sequence on the 3D surface of a single 3dMD reference frame and the 3dMD software will generate a coordinate map throughout the sequence within a correct temporal context.

The 3dMDtempus Software provides the bridge between automated traditional point tracking and sparse meshing techniques to expressing movement in terms of dense surface deformation and classification enabling a new paradigm of tools which permit comparative regional behavior to be enumerated. Feature points to track can be uniformly sampled, detected for generic facial features, or defined by a mesh mask. This capability enables a user to quantify and model the essential subtleties of human behavior and/or reactions to stimuli.

The 3dMDtempus Software generates thousands of individual surface points to be transitionally tracked as xyz coordinates from one 3dMD frame to another in six degrees of freedom within the context of the subject’s yaw, pitch, and roll movements. This level of anatomical tracking precision enables clinicians and researchers to accurately measure and quantify anatomical function, expressions from extreme to micro, and soft tissue deformations in a sequence or isolated.
