Problems solved by technology
[0003] This requires fast, convenient and accurate judgment of the range of the horizontal angle between the trees. However, in the current judgment method, the naked eye judgment is very inaccurate, and the common angle measuring instrument is very inconvenient to measure the horizontal angle between the trees. Therefore, it is labor-intensive and time-consuming to measure, and sometimes the judgment is not accurate

Embodiment Construction
[0018] A preferred embodiment of the laser goniometer of the present invention is as figure 1 , figure 2 As shown, it includes a housing 1, and a laser emitting device 4 is provided inside the housing 1. The laser emitting device 4 is provided with a plurality of light-emitting points, which can emit laser beams to the outside. The plurality of light-emitting points include a reference light-emitting Point 3 and multiple angle luminous points, the angle between the reference luminous point 3 and the laser beam 7 emitted by the angle luminous point is 0-180°, which can be 0, 30, 45, 60, 72, 90° and other preferred angles. It can also be within the included angle range of 60-120° or 60-90°.
[0019] In a specific embodiment, there are two above-mentioned angle luminous points, which are respectively a standard angle luminous point 5 and a right angle luminous point 6, wherein the distance between the laser beam emitted by the standard angle luminous point 5 and the laser beam...

The invention discloses a laser angle measuring device which comprises a shell, a laser emitting device is arranged inside the shell and provided with a plurality of light emitting points that comprise standard angle light emitting points and right angle light emitting points; wherein, a laser beam emitted by the standard angle light emitting points takes an included angle of 72 degrees with a laser beam emitted by benchmark light emitting points; a laser beam emitted by the right angle light emitting points takes an included angle of 90 degrees with the laser beam emitted by the benchmark light emitting points; a compass is arranged on the shell. The laser angle measuring device can conveniently determine the range of the included angles between forest trees through the laser beams that are emitted by the benchmark light emitting points and the angle light emitting points, has simple structure, convenient use and accurate determination, and is especially applicable for determining the range of the included angles between wild forest trees.
Description
technical field [0001] The invention relates to a device for judging angle ranges, in particular to a device for judging angle ranges among multiple trees. Background technique [0002] When judging the distribution pattern of forest trees in the field, it is often necessary to judge the horizontal angle formed by a single tree and its nearest adjacent trees, analyze the uniformity of the distribution of multiple nearest adjacent trees around the tree, and calculate the distance between each tree and its surroundings. Multiple nearest neighbor trees are the smallest structural unit, and the tree distribution pattern of the whole stand is analyzed. At this time, it is generally not necessary to accurately measure the horizontal angle between trees, but to determine which angle range the horizontal angle between trees is in, or whether it is greater than or smaller than a certain standard angle, and then use statistical methods Analyze the tree distribution pattern.
