Patent Abstract: Embodiments of this application provide an image processing method and device, which include: obtaining an image to be processed and determining the feature detection result of the image; based on the image and the feature detection result, determining a center point probability map and corner point offset information map; based on these maps, determining at least one first corner point set, and then determining at least one target polygon within the image to be processed according to the first corner point set. This scheme can predict the related information of center points and corner points by combining the feature detection results of the image, and determine target polygons in the image based on the output results. It has strong robustness, more accurate and efficient corner point positioning, high detection accuracy, and can meet high-precision detection requirements.
