Abstract: Rapid reconstruction of plant three-dimensional structure and three-dimensional visual analysis of crop morphological structure, growth process and phenotype measurement are hot and difficult points in digital plant and crop breeding research. This paper summarized the research status and the mainstream technology of plant three-dimensional reconstruction, and classified and compared the methods, principles and technical advantages of various technologies. The research progress, technical principle and related hardware and software system platform of multi-view image three-dimensional reconstruction method SFM and MVS were emphatically introduced, and the application progress of multi-perspective image three-dimensional reconstruction in plant three-dimensional reconstruction in recent years were analyzed, the multi-perspective image three-dimensional reconstruction method had the advantages of low cost of data acquisition, high precision of point cloud acquisition and high quality of plant three-dimensional reconstruction. At the same time, the paper also pointed out the shortcomings of this technology and its future development trend, expected to provide useful reference for the development of plant three-dimensional reconstruction technology, the study of plant phenotypic omics and the development of low-cost and high-throughput equipment.
