Facility horticulture plant three-dimensional reconstruction method based on double-scaling three-dimensional digitized data

The invention discloses a facility horticulture plant three-dimensional reconstruction method based on double-scaling three dimensional digitized data, belonging to the technical field of computer graphics and including the following steps: S1. obtaining information of the morphological characteristics of stems and petioles of facility horticulture plants; S2. reconstructing three-dimensional mesh models of the stems and the petioles of the facility horticulture plants by utilizing the information of the morphological characteristics; S3. obtaining three-dimensional point cloud data of each leaf on the facility horticulture plant selected from the S1 by utilizing a three-dimensional scanner; S4. according to the three-dimensional point cloud data of each leaf obtained from the S3, generating a three-dimensional grid curved surface model of each leaf; and S5. reconstructing a whole morphological structure three-dimensional model of the facility horticulture plant by utilizing the models constructed in S2 and S4. The method is convenient, fast and precise.
