A method for chip collection and a method for chip positioning are provided. The method for chip collection includes that: an image to be detected is obtained; chip position information of a comparison image with a highest matching degree with the image to be detected is obtained from a database; a position of each of detection regions in the image to be detected is obtained based on the chip position information; an image of the detection region is obtained based on the position of each detection region; it is determined whether the image of the detection region includes the chip code image; and when the image of the detection region includes the chip code image, a chip code corresponding to the chip code image identified and the chip code is stored in the database.
