Abstract

The invention discloses a slope monitoring system capable of obtaining three-dimensional data of slope deformation, and relates to the technical field of slope engineering. The slope monitoring system comprises a monitoring device used for acquiring data indicating that a slope point to be monitored protrudes frontwards or is depressed backwards; an image collecting device used for collecting data of a horizontal coordinate of the slope point to be monitored; and an information processing device used for comprehensively calculating the data acquired by the monitoring device and the image collecting device to obtain the three-dimensional data of slope deformation. The slope monitoring system disclosed by the invention has the beneficial effects that the information processing device establishes an original three-dimensional coordinate system and a conversion three-dimensional coordinate system to calculate the three-dimensional data of a deformed slope relative to a slope on the previous day and the three-dimensional data relative to a slope at the initial state, the monitoring system is not affected by weather factors, can monitor slope deformation in real time and can accurately determine that the slope protrudes forwards or backwards, move leftwards or rightwards or move upwards or downwards, thereby providing accurate data support for a technician to analyze the slope deformation condition and the slope stability subsequently.

Description

technical field [0001] The invention relates to the technical field of slope engineering, in particular to a slope monitoring system capable of obtaining three-dimensional data of slope deformation and a method for obtaining three-dimensional data of slope deformation. Background technique [0002] In recent years, with the development of our country's transportation, the shift from construction-oriented to construction-maintained, more and more slope safety status has attracted the attention of maintenance personnel. The long-term manual manual monitoring of slopes has problems such as low monitoring frequency, severe weather effects, and slow analysis and alarm speed. It has been difficult to meet the current needs for slope monitoring. The use of long-distance high-precision laser ranging sensors for slope monitoring is an emerging slope monitoring technology. It has high monitoring accuracy, simple engineering installation, and low cost. Its monitoring effect is graduall...
