Abstract

Abstract: A color rendering method for rice leaves based on SPAD data distribution image was presented. Rice leaf image was collected and SPAD value was measured by field rice sample test. The relationship model between SPAD values and RGB value of leaf image was analyzed and constructed, and the R² was 0.932 8, 0.833 1, 0.562 3 respectively. This showed that there was a correlation between SPAD and the red and green color of the leaf image. By the SPAD data distribution image, the spatial distribution of SPAD value on the leaf surface is described. The leaf surface color difference and the change with the growth time were simulated. Through Microsoft's Direct3D9.0 graphics library and vc ++ programming, the visual simulation of rice leaf color change process based on the previous 3D model of rice leaf was achieved. The method has good generalization.
