Landslide deformation three-dimensional infrared monitoring device based on RGB color sensors

Abstract

The invention discloses a landslide deformation three-dimensional infrared monitoring device based on RGB color sensors. The device is composed of a plurality of markers and a plurality of detection modules. Each marker and the corresponding detection module are respectively fixed on a landslide monitoring point. According to the invention, the infrared color sensors and humidity sensors are integrated, the three-primary-color reflection ratio of marker color are measured, and the water pressure in the gap of the landslide is detected due to the fact that different marker humidities are corresponding to different color reflection ratios. The color sensors are capable of accurately discriminating very similar colors and even different tones of the same color, and the detection precision is extremely high. Combined with the air humidity data detected by the humidity sensors, the weather change trend of the monitored position can be pre-estimated, the landslide generation early-warning time is advanced, and a time displacement cloud atlas is drawn according to a drawing module, so that the landslide volume is estimated, and full preparation is made for subsequent protection and treatment.

Description

technical field [0001] The invention relates to a geological disaster monitoring device, in particular to a device for three-dimensional infrared monitoring of landslide deformation based on an RGB color sensor. Background technique [0002] China is a country with many mountains and hills, and landslide disasters occur frequently, especially in the southwest of China, where the topography is complex and varied. The surface and cutting surface create favorable conditions for the occurrence of landslides; at the same time, rainfall has a great impact on landslides. Long-term rainfall, a large amount of rainwater infiltrates, makes the rock and soil on the slope in a saturated state, the effective stress is greatly reduced, and the resistance of the slope The shear strength decreases accordingly, and at the same time, the heavy inflow of rainwater also increases the weight of the sliding body; at the same time, the movement of groundwater also softens the sliding surface and r...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the above-mentioned existing landslide monitoring mainly adopts simple displacement monitoring method, which cannot detect slope body pore water pressure while detecting displacement changes, so that the cumulative displacement value of landslide deformation may occur before reaching the calibration imminent sliding state. , so that the detection reliability is low; the weather conditions cannot be predicted according to the air humidity change trend at the monitoring location, the early warning time of the landslide cannot be advanced, and the time displacement cloud map drawn by the drawing module cannot be used to estimate the landslide volume and monitor the landslide disaster At the same time, it is unable to make sufficient preparations for subsequent protection and treatment, and a device based on RGB color sensor for three-dimensional infrared monitoring of landslide deformation is provided.
