Title:
ESTIMATION SYSTEM, ESTIMATION METHOD, AND ESTIMATION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/009661
Kind Code:
A1
Abstract:
An estimation system includes at least one processor. At least one processor acquires a video showing a plant such that the position of the plant changes, performs object detection on each of the plurality of frames of the video to detect instances corresponding to the plant, identifies the transition of the instance including two or more feature points corresponding to two or more nodes of the plant as an instance history, estimates the position of each of the two or more nodes on the basis of the transition of each of the two or more feature points included in the instance history, and estimates an internodal distance, which is a distance between two nodes, on the basis of the estimated two or more positions.
