TECHNICAL FIELD
[0001] The utility model relates to the field of geological monitoring, especially relates to a crack dip angle monitoring alarm device. BACKGROUND
[0002] The existing crack and dip angle test in geological disasters generally adopts a sensor, obtains the deformation of the geology through the displacement of the sensor. However, in some monitoring areas, the installation is difficult, for example, the cliff or landslide position, the sensor is installed at the predetermined position, which is dangerous for the installer, and the sensor is also prone to failure for this type of geological monitoring.
[0003] Of course, there are also cameras for monitoring crack dip angles, but they are generally single camera monitoring, so there are still deficiencies in monitoring. The single image is too large (the monitored area is large), and the size is too small (the monitored area is small), which affects the monitoring accuracy.
[0004] Of course, there are also multiple cameras for monitoring, but they are large in size and scattered, which is not convenient for installation (such as leading wires and setting data lines, etc.), and the interaction and distance between the cameras are different, so the image needs to be filtered in the later stage. In real-time monitoring, the data is large. UTILITY MODEL CONTENT

[0010] The focal lengths of the first camera device and the second camera device are different.
[0011] In actual design, the first camera device and the second camera device can be used to observe the terrain and the topography of the monitoring area at a long distance, the first image data and the second image data are acquired through the first camera device and the second camera device, and through the setting of the focal length difference, although the scene entering the light exit hole is the same, the first image data and the second image data acquired under the action of the focal length difference are different, which can be understood as one being an enlarged version and the other being a reduced version, so that more accurate comparison and monitoring of the crack and the inclination of the topography and the terrain can be realized.
[0012] The monitoring data include the first original image, the second original image, the first image data and the second image data of the monitoring area, whether there is differentiation is acquired through comparison of the first original image and the first image data, whether there is differentiation is acquired through comparison of the second original image and the second image data, at the same time, whether there is differentiation is confirmed through filtering comparison of the first image data and the second image data, and then the crack inclination can be accurately acquired through the comparison module, and a warning can be given to the differentiation of the data, for example, if the image differentiation value is greater than 3 degrees, the threshold is exceeded.
