Problems solved by technology

[0002] In recent years, emerging new technologies have greatly promoted the development of agriculture, forestry and garden informatization, especially the development of UAV low-altitude remote sensing platform, which has greatly improved the means of information acquisition in forestry and garden surveys, but tree High-precision measurement has always been an urgent problem to be solved in agricultural and forestry surveys. Traditional ground measurement methods such as altimeters have low measurement efficiency and cannot be applied on a large scale. Although the new UAV lidar remote sensing method can complete large-scale Tree height measurement, but at a high cost

Abstract

The invention discloses a system and method for extracting plant height based on an unmanned aerial vehicle image DSM. According to the method, based on the DSM (Digital Surface Model) extraction technology of unmanned aerial vehicle photography images, the vegetation height data can be accurately obtained by utilizing digital elevation model extraction of vegetation filtering and vegetation crowntype automatic identification based on computer deep learning, and compared with a laser radar remote measurement mode, the measurement cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of ecological environment protection monitoring, in particular to a system and method for extracting plant height based on UAV image DSM. Background technique [0002] In recent years, emerging new technologies have greatly promoted the development of agriculture, forestry and garden informatization, especially the development of UAV low-altitude remote sensing platform, which has greatly improved the means of information acquisition in forestry and garden surveys, but tree High-precision measurement has always been an urgent problem to be solved in agricultural and forestry surveys. Traditional ground measurement methods such as altimeters have low measurement efficiency and cannot be applied on a large scale. Although the new UAV lidar remote sensing method can complete large-scale Tree height measurement, but at a high cost. Contents of the invention [0003] The purpose of the present invention is to ...
