Video image acquisition device for slope safety monitoring

Abstract

The invention relates to the technical field of side slope monitoring devices, and provides a video image acquisition device for side slope safety monitoring, which comprises: a mounting bracket, wherein the mounting bracket comprises a mounting swing arm provided with an acquisition module, and a supporting arm is further arranged on the mounting bracket; a vibration detection module which is used for detecting whether the acquisition module shakes or not; a control module which is used for controlling the supporting arm to move reversely and return to the initial position when jittering is detected; an environment detection module which is used for detecting environment parameters; a storage module, wherein an environment threshold table is preset in the storage module, the environment threshold table comprises multiple sets of environment thresholds and sensitivity corresponding to the vibration detection module, the sensitivity corresponding to the high environment threshold is low, and the sensitivity corresponding to the low environment threshold is high; and a matching module which is used for matching environment thresholds matched with the detected environment parameters and corresponding sensitivities from the storage module, wherein the control module is also used for adjusting the sensitivity of the vibration detection module according to the matched sensitivity.

Description

technical field [0001] The invention relates to the technical field of slope monitoring devices, in particular to a video image acquisition device for slope safety monitoring. Background technique [0002] The side slope refers to the slope with a certain slope made on both sides of the roadbed to ensure the stability of the roadbed. Due to the influence of its complex geological conditions, slope stability has always been the focus of geotechnical engineering. At present, when monitoring the slope stability problem, the slope stability is obtained by analyzing the slope image after collecting the slope image. In the prior art, cameras are usually used to collect slope images. However, since the camera is installed outdoors and is directly exposed to the air, when the environment where the camera is located is windy, the camera will shake under the influence of the wind, resulting in unclear images collected and affecting the analysis results . [0003] In the prior art,...

Problems solved by technology

In the prior art, when detecting vibration, the sensitivity of the detection module is usually fixed. However, since the shaking of the camera is caused by environmental factors, as the environmental factors change, the vibration amplitude of the camera will It will also change; therefore, if the sensitivity of the detection module is set lower, the shaking of the camera caused by minor environmental factors will not be detected, which will affect the accuracy of the detection results, and if the sensitivity of the detection module is set to If the sensitivity setting is high, other factors of the environment where the camera is located will also be introduced. For example, when detecting camera shake, it should only need to detect the vibration of the camera, but if the sensitivity is too high, it may also detect nearby devices. The vibration is also detected and used as the detection result, which will also reduce the accuracy of the detection result
