Remote and rapid monitoring and alarming device and method for displacement and gesture of sliding mass

Abstract

The invention discloses a remote and rapid monitoring and alarming device and method for the displacement and the gesture of a sliding mass, and relates to a target monitoring technique. The method carries out remote automatic monitoring on the potential sliding mass in the earthquake and landslide disaster emergency rescue, and monitors the changes of the position and the gesture of the potential sliding mass, and once the changes reach or exceed the preset safety limit, the acousto-optic alarm is carried out to warn the field personnel to take safety measurements or depart from the danger area. The device has mature technique, lower cost, simple structure, low power consumption and higher accuracy, is convenient in operation, is convenient for outdoor monitoring, provides the insurance for natural disaster rescue, and generates enormous economic and social benefits.

Description

technical field [0001] The invention relates to the technical field of target monitoring, and relates to a single digital camera-based device and method for long-distance rapid monitoring and alarming of the displacement and attitude of a landslide body. Background technique [0002] Entering the new stage of the new century, with the acceleration of economic and social development, the intensification of economic activities, the over-exploitation of natural resources, the sharp increase in population, and the deterioration of the ecological environment, the natural disasters in our country are showing an increasingly serious development trend. Work is facing severe challenges. Among the many natural disasters, earthquakes are disasters caused by local rapid rupture of the earth's internal medium. There are three main seismically active belts in the world, among which my country is located in the Circum-Pacific Seismic Belt and the Eurasian Seismic Belt, and China's Taiwan r...

Problems solved by technology

The advantage of this type of binocular or multi-eye measurement system is high accuracy, but the disadvantage is that the system is huge, complex in structure, requires precise installation and calibration, relatively high power consumption, and requires high stability in the measurement environment. It is also relatively complicated, and data processing cannot be completed in real time on site, so it is difficult to apply to the field environment

In addition, conventional change detection algorithms based on image data require a relatively stable background, which is only suitable for indoor environments with relatively stable illumination. For outdoor environments with complex illumination changes, even if the target does not undergo any displacement and attitude changes, when the ambient illumination occurs Changes, or shadow occlusion occurs, the existing change detection algorithm also thinks that the target has changed, causing false alarms
