Problems solved by technology

Contact measurement mainly uses a diameter ruler, which surrounds the trunk for a week. The measurer must be close to the trunk, and the measurement efficiency is very low. For hundreds of thousands of seedlings, it is difficult to measure the diameter of the seedlings.
Among the non-contact measuring devices, the measuring system using the triangulation principle and the principle of laser ranging requires a relatively stable platform to measure; in addition, the measuring device that uses image acquisition and processing cannot avoid using a distance ruler to measure the distance between the image acquisition point and the point to be measured. The distance between trees and the measurement speed are relatively slow, so it is not suitable for the measurement environment with a large number of seedlings

Abstract

The invention discloses a non-contact tree diameter at breast height measuring method and system based on computer vision. Hardware equipment comprises an RFID tag, a smart phone, RFID read-write equipment and handheld equipment. A tree trunk photo with a color label is shot through the smart phone, and the photo is transmitted to a server to be subjected to image processing, and the diameter at breast height of the tree to be measured is obtained after processing; the color label is attached with an RFID label, an RFID read-write device identifies the RFID label of the tree, and the measureddiameter at breast height of the tree and the RFID label of the tree are correspondingly stored in the server. The device in the embodiment of the invention is simple and convenient to carry, and thewhole system can improve the efficiency of tree measurement and management.

Description

technical field [0001] The invention belongs to the technical field of forestry measurement, in particular to a non-contact tree diameter measurement method and system based on computer vision. Background technique [0002] DBH is an important basis for measuring the price of seedlings. In the inventory of tree diameters at breast height in nurseries, the measurement of tree diameters at breast height is extremely important. [0003] Existing measurement techniques can be divided into two categories: contact measurement and non-contact measurement. Contact measurement mainly uses a DBH ruler around the trunk for a week. The measurer must be close to the trunk, and the measurement efficiency is very low. For the number of hundreds of thousands of seedlings, it is difficult to measure the diameter of the seedlings. Among the non-contact measuring devices, the measuring system using the triangulation principle and the principle of laser ranging requires a relatively stable pla...
