ZCam a video camera that can record data to the part-object (which is used to create 3D models), video, and then produced by 3DV Systems.Tehnologija is based on the principle of "flight time" is based. In this technique reflects the size of 3D datareceiving infrared wave in the video scene and detecting light from the surface of the object in the video scene. Be met through the use of a variable time infrared waves to the target object and time again, the distance can be calculated and then used to create 3D data on all objects in the scene.
