Image acquisition correction system and method

The invention provides an image acquisition and correction system and method, and relates to the technical field of image processing, and the system comprises an image sensor, an AD converter, an image correction device and a memory. The image sensor carries out image acquisition on a to-be-detected object to obtain original image data; the AD converter performs analog-to-digital conversion on the original image data to obtain original pixel data; and the image correction device corrects the original pixel data based on the correction parameter group to obtain corrected pixel data, and sends the corrected pixel data to a memory for storage. According to the system, the amplification factor of the AD converter, the offset of the AD converter and the light source light emitting time of the image sensor are corrected in advance, and the pixel correction coefficient used for correcting each pixel point is stored in advance, so that in the application process of the system, the corrected image of the object to be
