Image processing method, device and system based on artificial intelligence and storage medium

The invention discloses an image processing method, device and system based on artificial intelligence and a storage medium. The method comprises the following steps: acquiring a calibration image of a calibration device, wherein the calibration device comprises a pattern plate with a plurality of patterns; performing feature extraction on the calibration image to obtain a first feature map; inputting the first feature map into a frame regression network to output a plurality of regions of interest corresponding to the calibration device in the first feature map; a preset number of candidate frames are generated for each region of interest based on a preset prior frame, the size of each candidate frame is the same as that of the preset prior frame, and the preset number is determined according to the number of the patterns; and inputting all the candidate frames and the first feature map into a center regression network to obtain an image center point coordinate of each pattern in the calibrated image.
