The ZCamTM is a video camera that can
capture depth information (which is used to build the 3D model) along
with video and is produced by 3DV Systems. The technology is based on
the Time of Flight principle. In this technique, 3D
depth data is generated by sending pulses of infra-red light into the
scene and detecting the light reflected from the surfaces of objects in
the scene. Using the time taken for a light pulse to travel to the
target and back, the distance can be calculated and used to build up 3D
depth information for all objects in the scene. (Via 3dvsystems)
