Visible light imaging system and method based on continuous multi-frame pictures

The invention discloses a visible light imaging system and method based on continuous multi-frame pictures. The visible light imaging system comprises a control module, an LED lamp, a power module, a CMOS camera and an image processor. The control module is a single chip microcomputer with a timer inside, and is used for controlling the duty ratio of the LED lamp to be unchanged, alternately flickering at two given frequencies, and circularly flickering according to a specific flickering frequency alternating mode; the LED lamp is used for flickering and emitting light, providing illumination and containing internal information; the power supply module is used for supplying power to the LED lamp and the single chip microcomputer; the image processor is used for processing videos shot by the CMOS camera, extracting continuous multiple frames of images, processing the images and decoding the images to obtain information of the LED lamp; and the CMOS camera is used for carrying out video shooting on the luminous
