Embodiment 1

[0026] In order to realize the vibration recognition amplification method, the first embodiment also discloses a vibration recognition amplification system, such as figure 2 As shown, including selection of identification module, amplification module, processing module and multiple camera modules, selection of identification module signal connection processing module, amplification module signal connection processing module, camera module installation and layout according to actual conditions, camera module signal connection processing module, The selected recognition module can use the existing image processing algorithm to match the monitoring points on the monitoring image according to the preset target. The magnification module can use the existing magnification algorithm for image magnification and interpolation algorithm for image processing. The processing module can use the existing PC machine, the camera module can use the existing camera.

Embodiment 2

[0034] The difference from Embodiment 1 is that it also includes step S6, collecting environmental information through the environmental module and sending it to the processing module. The environmental module can be a panoramic camera, allowing the processing module to identify the vibration triggering factors in the environmental information, and judge the displacement according to the vibration triggering factors Is the range accurate.

[0035] Collect environmental information, such as the image information of the entire area to be tested, and identify the vibration trigger factors in the environmental information, such as earthquake information, car accidents or construction, etc., and then judge whether the displacement range is accurate according to the vibration trigger factors, such as identifying construction vibration triggers factor, but the displacement range is very small, it can be judged as inaccurate, so as to accurately measure the displacement range.

Abstract

The invention relates to the technical field of video monitoring of geological deformation, and in particular relates to a vibration identification and amplification method. The method comprises the steps that S1 monitoring pictures are shot in real time through a camera module fixed outside a to-be-monitored area; S2 a processing module obtains monitoring pictures and sends the monitoring pictures to a selection recognition module to recognize monitoring points in the monitoring pictures and add position marks, the processing module compares the position marks on the multiple monitoring pictures and counts the position marks, and the monitoring point with the maximum count value of the same position mark serves as an amplification position; S3 the amplification position and the plurality of monitoring pictures are sent to an amplification module by the processing module, the amplification module amplifies the plurality of monitoring pictures according to the amplification position, and the amplified monitoring pictures are sent to the processing module; and S4 the processing module compares the vibration displacement information of the plurality of monitoring points and draws vibration displacement tracks at the monitoring points in the to-be-monitored area. Targets such as a preset target are not needed for measurement, and the continuity of vibration displacement recognition is improved.

Description

technical field [0001] The invention relates to the technical field of video monitoring of geological deformation, in particular to a vibration identification and amplification method. Background technique [0002] Areas such as bridges, tunnels, mining areas, and slopes are special structures produced in the process of human construction activities. The displacement monitoring of bridges, tunnels, mining areas, and slopes is related to the service life of structures and the safety of life and property. Displacement is the structure Therefore, it is very important for vibration monitoring in areas such as bridges, tunnels, mining areas and slopes. [0003] At present, the vibration monitoring method for areas such as bridges, tunnels, mining areas, and slopes is to first arrange monitoring objects such as targets in the target area to be monitored, and then monitor the displacement of the monitoring objects in real time to judge the bridge vibration according to the displace...
