The invention discloses a method and system for monitoring the three-dimensional deformation of a side slope based on monitoring-level cameras, and the method comprises the steps: controlling a plurality of monitoring cameras to synchronously collect images; calibrating the internal and external parameters of the plurality of monitoring cameras through a total station or a GPS; carrying out the aberration correction of the collected image through the plurality of monitoring cameras; carrying out the analysis of the images in real time through a network cloud platform, obtaining the three-dimensional deformation of the side slop, and returning a result for display. The method can achieve the collection of the images through the plurality of monitoring cameras, obtains the three-dimensionaldeformation of the side slop and achieves the returning of the result, thereby improving the measurement efficiency, improving the detection accuracy, and effectively reducing the disasters.

Description

Technical field [0001] The invention relates to the technical field of engineering detection, and in particular to a method and system for monitoring three-dimensional deformation of a slope based on a surveillance camera. Background technique [0002] my country is a mountainous country. The recent frequent occurrence of landslide accidents has not only caused a large amount of property losses, but also seriously threatened the safety of human life and caused a serious impact on society. At the same time, with the development of engineering construction in China, a large number of slope projects have appeared in various regions. However, with changes in the environment and weather, many slopes have gradually become unstable, resulting in landslides, causing damage to roads, villages, towns, mining areas and other facilities. It also seriously endangers the safety of human life and property. Side slope refers to a naturally formed slope with a certain slope composed of rocks and...

Problems solved by technology

This type of camera is specially used for indoor precision measurement. Although the technical parameters such as resolution and frame rate are high, and the image quality is good, but the degree of integration is poor, the operation is complicated, the environment adaptability is poor, and the price is expensive.

In field measurement applications, it is often difficult to apply

Surveillance cameras have a high degree of integration and are suitable for long-term monitoring in the field, but their image quality is poor, which affects measurement accuracy

At the same time, due to the large size of the field of view (the size of the calibration plate generally needs to be in the same order as the size of the measured object, which is obviously impossible to achieve in the slope measurement environment), the internal and external parameters of multiple cameras cannot be calibrated using the traditional method. Two-dimensional calibration plate method for calibration

Due to the above two difficulties, the application of this method in slope deformation monitoring is severely limited, resulting in the extremely low monitoring rate of slopes in my country, and frequent occurrence of landslide accidents.
