Water and soil conservation monitoring method based on three-dimensional image reconstruction and analysis technology

Abstract

The invention relates to a monitoring method. The invention provides a water and soil conservation monitoring method based on a three-dimensional image reconstruction and analysis technology. The method comprises the steps that: firstly, a system periodically obtains a plurality of initial images from different angles of one region to be detected; the system carries out registering on the plurality of initial images; the system carries out image point cloud data extraction on the registered images; then the system generates a TIN triangulation network according to the image point cloud data and further realizes the three-dimensional model reconstruction of the region to be detected, and a three-dimensional model of the region to be detected is generated; and finally, the system carries out length, area and size quantified calculation on a relative position, compares the calculated values with corresponding values of the previous cycle and analyzes the consistence of water and soil conservation. The application of the three-dimensional image reconstruction and analysis technology fills the gap of quantitative monitoring content irregular monitoring methods and means in the water and soil conservation monitoring work, and the automatic degree of the field monitoring work is improved. The monitoring method is applicable to water and soil conservation.

Description

technical field [0001] The invention relates to a monitoring method, in particular to a monitoring method for soil and water conservation. Background technique [0002] Soil and water conservation monitoring refers to the long-term investigation, observation and analysis of the occurrence, development, hazards and benefits of soil and water conservation. Through soil and water conservation monitoring, understand the types, intensity and distribution characteristics of soil and water loss, hazards and their impact, occurrence and development, and dynamic trends in the target area, and make macro decisions on comprehensive control of water and soil erosion and ecological environment construction, as well as scientific, reasonable and systematic measures. It is of great significance to lay out various measures of water and soil conservation. [0003] Soil and water conservation monitoring of development and construction projects is a newly developed project in our country in r...
