The invention provides a high-
throughput calculation method for
crop plant height. The method comprises the following steps: acquiring a
color image, an
infrared image and a depth image of a
crop sample group; and carrying out
image registration on the
color image and the depth image, and constructing a
point cloud image with color information; extracting
crop canopy three-dimensional point cloudaccording to the
point cloud image with the color information; extracting a
canopy image corresponding to each crop in the
crop sample group according to the crop
canopy three-dimensional
point cloud,and calculating the
plant height of each crop through a high-
throughput calculation method. According to the embodiment of the invention, the
plant height of each pot of crops in the group crops canbe quickly and accurately calculated; Compared with a traditional plant height measuring method which utilizes a ruler, a handheld
laser range finder and other devices to manually measure the verticallength from the highest point of a canopy to the root of a plant, the high-
throughput calculation of the plant height of the crop is realized, and the method is quicker, simpler and more convenient.Compared with a
network camera remote
phenotype measurement method, the accuracy of crop plant height measurement is improved.
