Method and device for directly seeding plant growth three-dimensional formethod and device for directly broadcasting three-dimensional shape of plant growth

Abstract

The embodiment of the invention provides a method and a device for directly seeding broadcasting a three-dimensional shape of a plant growth. The method includes the steps of According to the local section unit three-dimensional shape information and the prior growth law of the to-be-live-broadcast plant, acquiring a virtual three-dimensional form of the plant to be directly sown according to the local section unit three-dimensional shape information and the prior growth law of the to-be-live-broadcast plant; acquiring a virtual top projection image corresponding to the real top projection image according to the virtual three-dimensional form; comparing the accumulated pixel density of the virtual top projection image with the accumulated pixel density of the real top projection image; if the difference rate between the cumulative pixel density of the virtual top projection image and the cumulative pixel density of the real top projection image is smaller than a preset difference rate,; if yes, taking the virtual three-dimensional form serves as a plant growth three-dimensional form, displaying the plant growth three-dimensional form is displayed through a transparent display screen, plant growth is more visual, scientific and interactive, and the plant growth three-dimensional form can be accurately displayed in real time.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional graphics generation, and in particular relates to a method and a device for live-broadcasting the three-dimensional shape of plant growth. Background technique [0002] The three-dimensional shape of the plant changes consistently during the growth process. If the three-dimensional shape of the plant can be continuously obtained and transmitted to the remote end for 3D model browsing in real time, it is of great significance for real-time acquisition of the three-dimensional shape of the plant growth process. [0003] The general image and video acquisition technology can only obtain the two-dimensional projection of the three-dimensional shape of the plant in real time, but the 3D digital equipment is used to collect the three-dimensional shape information of the plant, and based on this information to reconstruct the three-dimensional model of the plant group, because the 3D digital equ...
