Embodiment Construction
[0037] The technical scheme in the embodiment of the present invention, general idea is as follows:
[0038] In this embodiment, the vertex coordinates of the checkerboards to be painted are determined first, and then the checkerboards to be drawn are closed by connecting lines so that the coloring can be done directly by filling colors. Each of the steps can be automatically executed by computing equipment without manual drawing, which greatly improves the drawing efficiency and saves labor costs and time costs.
[0039] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure a...

The invention discloses a drawing method and device of a checkerboard test chart, equipment and a medium, and the method comprises the steps: determining the coordinates of a starting point accordingto the position of a frame of a test chart, the side length of a unit checkerboard and the inclination angle of the checkerboard relative to the frame, and enabling the starting point to be the midpoint of a target checkerboard in the test chart; according to the coordinates, the side length and the inclination angle of the starting point, determining vertex coordinates of the target checkerboard,and connecting the vertex of the target checkerboard to complete drawing; according to the coordinates, the side lengths and the inclination angles of the starting points, determining vertex coordinates of all the checkerboards needing to be drawn in the test chart, and connectingthe vertexes of the checkerboards needing to be drawn to complete drawing of all the checkerboards needing to be drawn; and filling the target checkerboard and the checkerboard to be drawn with colors to form a checkerboard test chart. According to the method, the device, the equipment and the medium provided by theinvention, each drawing step can be automatically executed by the computer, so that the drawing efficiency of the checkerboard test chart is improved, and the manpower and the time are saved.
Description
technical field [0001] The invention relates to the technical field of cameras, in particular to a method, device, equipment and medium for drawing a checkerboard test chart. Background technique [0002] Before the camera module is shipped, in order to ensure the actual use effect, various tests are often required. Many tests on camera modules require the preparation of corresponding test charts, among which, the resolution test requires the preparation of checkerboard test charts. [0003] The checkerboard test chart is a black and white checkerboard test chart. The current method of drawing a checkerboard test chart is to manually draw staggered straight lines to form a checkerboard shape according to the parameters of the required checkerboard test chart, and then fill in the required color The checkerboard grids are colored, and the drawing process is complex and time-consuming. Contents of the invention [0004] In view of the above problems, the present invention ...
