摘要：

The accurate measurement of diameter at breast height (DBH) is essential to forest resources inventory, management, and carbon cycle modeling. Monocular vision passive measurement method based on a smartphone is a technique that allows for automatic, portable, and mobile measurement of DBH. Here, we propose a method for measuring the DBH of multiple trees from a single image taken by a smartphone camera, using machine vision and close-range photogrammetry technology. First, we present a visual segmentation approach based on an improved frequenc...
