The invention discloses a
fruit tree morphological structure three-dimensional (3D)
reconstruction method based on multi-
scale measurement data, and the method provided by the invention belongs to the technical field of computer graphs and comprises the following steps: S1, extracting a skeleton of
fruit tree branches from an original three-dimensional
point cloud data of the
fruit tree obtained by a three-dimensional
scanner, and reconstructing a three-dimensional model of a fruit
tree trunk from the skeleton; S2, obtaining the morphological feature information of a fruit tree sprout in a sampling manner, and constructing a three-dimensional model of a plurality of sprouts; S3, obtaining three-dimensional
point cloud data of a plurality of fruit tree leaves in sampling manner by the three-dimensional
scanner, reconstructing a three-dimensional model of the plurality of leaves to serve as a leave
template library in the reconstruction of the three-dimensional model of the fruit tree morphological structure; S4, constructing a space
distribution model of different types of branches and leaves at a fruit
tree canopy according to the measured form feature information of branches and leaves at the fruit
tree canopy; and S5, using the results from the step 1 to the step 4 to reconstruct a whole morphological structure three-dimensional model. The method provided by the invention is simple, convenient, rapid and accurate.
