Embodiment 1
[0057] In this embodiment, a blank rectangular paper is selected and placed on a white smooth desktop (no texture information), and the paper is moved and rotated on the desktop at will, and the paper is obtained in real time and continuously to move and rotate at will on the desktop Video images of the process.
[0058] Get the first frame of the video image, select a corner of the paper, the size of the selected mark window is 32*32, coincide the center of the mark window with the vertex of the corner, and align the sides of the mark window with the edges of the paper The sides are parallel to get a marked area, record the position information of the center point of the marked area and use the rectangular area as the target area; for example figure 2 It is a schematic diagram of the target area marked in the first frame of video image. When determining positive samples and negative samples, h takes 8, and v takes 20, such as image 3 Schematic diagram of multiple sample im...
