Plant three-dimensional model database establishing method

The invention provides a plant three-dimensional model database establishing method. The method includes S1, performing data collection on a plant, and acquiring a geometric model of the plant according to collected information; S2, acquiring a keyword of the geometric model; S3, establishing and storing a corresponding relationship of the keyword and the geometric model so as to establish a plant three-dimensional model database. By the method, efficiency of plant three-dimensional geometric modeling can be improved.
