Abstract

The invention provides a standing tree chest diameter measurement method and device, relating to the technical field of tree measurement equipment. The standing tree chest diameter measurement devicecomprises a left cutting arm, a right cutting arm, a middle ruler arm, a controller, a first angle sensor, and a second angle sensor, wherein the left cutting arm and the middle ruler arm are connected in a rotating manner, a first rotary joint is formed at a joint, the right cutting arm and the middle ruler arm are connected in a rotating manner, a second rotary joint is formed at a joint, the middle ruler arm is provided with a middle tip, and distance between the middle tip and the first rotary joint and distance between the middle tip and the second rotary joint are equal. The standing tree chest diameter measurement method has high measurement efficiency, high accuracy and high portability, and can be used for measuring a chest diameter of a large tree.

Description

technical field [0001] The invention relates to the technical field of tree measuring equipment, in particular to a method and device for measuring the diameter at breast height of a standing tree. Background technique [0002] Standing tree diameter at breast height is the diameter of the tree at 1.3m from the rhizome. It is the most important measurement factor in forest surveying. Accurate and reliable acquisition of DBH data is very important. The traditional method of measuring DBH of standing trees is inefficient and requires manual reading and recording, usually using tools such as girth rulers and calipers. The girth is not suitable for measuring trees with thorns and secretions. Its wide ruler surface will lead to large measurement errors, and the surveyor needs to close his hands to surround the tree and then wrap the ruler head around the trunk for a week before tightening the ruler surface. The bark is finally read at the junction of the ruler head and the ruler...
