Problems solved by technology

For a long time, my country's forest resource management has a low level of automation, and the tools and methods are very backward. A survey will cost a lot of material, financial and manpower, and data processing often takes 1-2 years. This backward forest survey method often cannot catch up. The growth and change of the forest itself

Abstract

The invention discloses an instrument which can measure the chest diameter of a tree, the height of the tree and the area of a standard forest land and organically combines the technology of multifunctional measurement of the standard forest land and the technology of data intelligent management. A tree measurement instrument designed in the invention achieves the measurement of the diameter of the tree through employing the technology of ultrasonic ranging, achieves the measurement of the height of the tree through employing an MEMS triaxial accelerometer sensor, achieves the statistics and management of measurement data through employing a Windows Embedded CE6.0 management system, and is an instrument which is formed by the combination of hardware and software based on the ultrasonic sensor and the MEMS triaxial accelerometer. The working principle of the measurement instrument mainly comprises two parts: employing the image and distance information collected through the MEMS triaxial accelerometer sensor and a digital camera, and measuring the height of the tree through employing a triangular measurement method; employing the ultrasonic sensor to transmit and receive ultrasonic waves, and measuring the diameter of the tree through employing the ultrasonic distance measuring principle.

Description

technical field [0001] The invention relates to a measuring device, in particular to a tree measuring instrument system based on an ultrasonic sensor and a MEMS three-axis accelerometer. Background technique [0002] The 21st century is a new economic era characterized by the rapid development of high-tech industries and infinitely expanding information. The new economy puts forward newer and higher requirements for forestry science and technology whose main task is to protect, restore and improve the environment and use forest resources efficiently. According to the needs of my country's forestry management and felling operations, this project develops a tree measuring instrument with multiple functions such as measuring tree diameter at breast height, tree height, GPS positioning, area measurement of felled forest area, and tree management. The development, use and promotion of this instrument will further ensure the rationality, orderliness and safety of forest harvestin...
