Abstract

The invention discloses a portable non-destructive measuring device for grassland biomass. A RGB image acquisition module and a solid-state area array laser radar acquire a large number of high-resolution grassland RGB images and relative distance images respectively; a GPS module obtains GPS information of the current grassland area; and an embedded signal control and processing board obtains a complete grassland height distribution information of the tested area by performing statistics of distance difference value and histogram on the relative distance image, performs a calculation on the coverage of a RGB image of the grassland, and finally performs a grassland biomass calculation according to the large number of grass coverage data, the grassland height distribution data and the GPS information of the corresponding area. According to the portable non-destructive measuring device for grassland biomass, the grass biomass information can be comprehensively obtained in real time, andthe device is simple in structure and convenient to carry.

Description

technical field [0001] The invention belongs to the technical field of grassland information collection, and in particular relates to a portable non-destructive measuring device for grassland biomass. Background technique [0002] The measurement of grassland biomass is an important indicator to effectively reflect the growth of grassland, and can provide basic information for the succession trend and production potential of grassland. [0003] The measurement of grassland biomass includes the measurement of grassland coverage and height. The traditional measurement of grassland biomass is usually the measurement of grassland coverage and grassland height respectively, and then the biomass calculation is performed offline. Among them, the measurement of grassland coverage usually adopts the photographing method, and the measurement of grassland height usually adopts the ruler measurement method and sensor measurement method. Therefore, there are the following problems: 1. It...
