Working principle:
When shooting a scene, the light reflected by the scene is transmitted to the CCD through the lens of the camera. When the CCD is exposed, the photodiode is excited by the light to release the charge, and the current generated by the photodiode is controlled by the control signal circuit in the photosensitive element. The output of the transmission circuit, the CCD will collect the electrical signals generated by one imaging, and output them to the amplifier in a unified manner. The amplified and filtered electrical signals are sent to the A/D, and the A/D converts the analog electrical signals into digital signals. The size of the signal is directly proportional to the strength of the electrical signal, that is, the level of the voltage. These values are actually the data of the image. By processing the returned data, it can be used for smart car path recognition, tracking, and obstacle avoidance
