Title:

MACHINE VISION-BASED TREE IDENTIFICATION METHOD AND DEVICE

Document Type and Number:

WIPO Patent Application WO/2021/051264

Kind Code:

A1

Abstract:

A machine vision-based tree identification method and device. The method comprises: obtaining a top-view image comprising a tree (201); and processing the top-view image to obtain pixel position information of a pith and tree diameter information corresponding to the pith in the top-view image (202). According to a top-view image comprising a tree, a pith position and a tree diameter in the top-view image can be obtained automatically, thereby reducing labor cost and improving recognition efficiency.
