Generating Method of Planting Map for Three-Dimensional Rice Field Painting Based on Fixed Point Perspective

: There is a certain technical threshold for transferring the design drawing of fixed-point perspective three-dimensional rice field painting to planting drawing. This threshold hinders the promotion of rice field painting in cost sensitive areas. By analyzing the imaging principle and technical difficulties of rice field painting, according to the working principle of optical and visual imaging, the process of light and shadow projection of design pattern onto the ground is simulated by computer software, and the ground projection map is calculated. The projection map can be transformed into planting map, which greatly reduces the production time and difficulty of planting map.
