Zusammenfassung:The invention provides an analysis method and device for a reflective two-dimensional code picture, equipment and a medium, and the method comprises the steps: S1, carrying out the binarization processing of a two-dimensional code picture, obtaining a binary image, and carrying out the edge detection of the binary image, and obtaining an edge image; s2, performing two-dimensional code Pattern detection on the binary image to obtain a Pattern alternative point coordinate possibly being a Pattern pattern, and calculating according to the morphological characteristics of the binary image to obtain a Pattern center coordinate; carrying out inverse perspective transformation on the edge image, and determining a linear perspective change trend; s3, performing matching in the binary image according to the coordinates of the alternative Pattern points and the linear perspective transformation trend to obtain positions of three Pattern point pairs; and S4, positioning the position of a fourth point pair according to t
