Compared with stereo cameras or triangulation systems, ToF camera is small size, which is very suitable for some application scenarios that require light and small cameras. Such as face recognition, motion recognition, volume measurement etc.
ToF camera quickly calculate the depth information in real time, reaching tens to 100fps of ToF depth information. The binocular stereo camera needs to use complex correlation algorithms, and the processing speed is slow.
The depth calculation of ToF camera is not affected by the grayscale and features of the object surface, and it can perform three-dimensional detection very accurately. The binocular stereo camera requires the target to have good feature changes, otherwise the depth calculation will not be possible.
The depth calculation accuracy of ToF camera does not change with the change of distance, and can basically be stabilized at the cm level, which is very meaningful for some large-scale motion applications.
