Abstract

The invention provides a vegetation height measurement method, device and system and a storage medium. The method comprises the steps of obtaining a radar echo signal; respectively identifying data of echo sampling points obtained by vegetation reflection and data of echo sampling points obtained by ground reflection in the data of the target signal at each scanning point; by means of the data of each echo sampling point obtained through vegetation reflection, assigning the occurrence moment of the maximum gradient value in the data of the echo sampling points obtained through vegetation reflection to be a first numerical value, assigning the other moments to be second numerical values, and aiming at each echo sampling point data obtained through ground reflection, assigning the moment corresponding to the ground height in the data belonging to the echo sampling point obtained by ground reflection as a first numerical value and assigning the other moments as second numerical values to obtain a vegetation height curve. Therefore, a vegetation height curve is obtained, and the purpose of measuring the vegetation height is achieved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method, device, system and storage medium for measuring vegetation height. Background technique [0002] At present, under the scenario of forest resource investigation and dynamic change monitoring through remote sensing technology, it is necessary to measure the height of forest vegetation to meet the needs of forest resource management, supervision and sustainable use. [0003] In the prior art, optical remote sensing is mainly used to measure the vegetation height. In practical applications, although optical remote sensing can better reflect vegetation canopy information through spectral features, vegetation index features, and texture features, due to its poor penetrability, in dense forests, it will Loss of its ability to obtain information about the internal structure of forests leads to limitations in vegetation height measurements. [0004] It can be seen tha...
