Problems solved by technology

[0005] The inventor found in the process of realizing the present invention that the traditional collection method of standing tree information mainly adopts optical and mechanical principles because of its measuring tools, therefore, information collection has certain requirements on the observation environment, such as the observation environment is not open enough, and the trunks are closely connected to each other. In the occluded scene, there is a certain difficulty in information collection; in addition, due to the need to manuall

Abstract

The invention relates to a method and a device for collecting stumpage information. The method comprises the following steps of obtaining the height of an information collector who uses an intelligent mobile electronic device to collect the stumpage information, and determining the height from the intelligent mobile electronic device to the ground according to the height of the information collector; obtaining a current look-down angle of the intelligent mobile electronic device under the situation that a focusing point of a shooting center of the intelligent mobile electronic device is aligned to a lowest point of a detected stumpage, and calculating the distance between the intelligent mobile electronic device and the detected stumpage according to the height and the look-down angle; obtaining a current look-up angle of the intelligent mobile electronic device under the situation that the focusing point of the shooting center of the intelligent mobile electronic device is aligned to a highest point of the detected stumpage, and calculating the height of the detected stumpage according to the height, distance and the look-up angle. According to the technical scheme provided by the invention, the stumpage information collecting convenience and the information collecting efficiency are effectively increased, and the implementation cost for collecting the stumpage information is reduced to a larger extent.

Description

technical field [0001] The invention relates to the technical field of forestry, in particular to a method for collecting standing tree information and a device for collecting standing tree information. Background technique [0002] Standing tree information mainly includes: standing tree height and standing tree diameter at breast height, etc. Collecting standing tree information is one of the important contents of forest resource survey and operation design, and the accuracy of collected standing tree information will directly affect the quality of forest resource survey and the analysis results of forest growth status. [0003] The traditional collection method of standing tree information is: measure the height of the standing tree with measuring tools such as the Bruce altimeter, and measure the diameter at breast height of the standing tree with measuring tools such as girth or calipers. [0004] With the continuous development of technology, professional precision in...
