Visible Sensors

Visible cameras are either based on CMOS or CCD technologies.

Visible cameras have a standard parameter: frame rate. Images are taken at constant time intervals to acquire images. Thus, the way of receiving information is synchronized. In addition, they often have poor imaging effects in high-speed motion scenes or scenes with unsatisfactory lighting. 

Visible cameras can be classified into plane cameras, panoramic cameras, omnidirectional cameras (360 degrees), and fisheye cameras.
