capella tof cam3D camera gives us the distance image, i.e. the image shows the distance to the scene object in each pixel of the picture. All the images  are translated in real time.  Stereo-cameras use the binocular principle. Estimation of distances is implemented by juxtaposition of shots made from two different, but close positions (triangulation method). The juxtaposition of shots is implemented on the computing unit with the help of special algorithm. This method requires the presence of textures on the scene objects. 3D cameras based on structured light use the special image projection on the scene and shooting this image with the high resolution camera. The distance is calculated by algorithmic processing. Such 3D cameras do not require the texture on the scene objects, but still need the computing unit. Read more
