Embodiment 1

[0071] Crack monitoring method caused by foundation pit displacement, refer to figure 1 ,include:

[0072] 101. Determine the best shooting point according to the crack position, so that the monitoring personnel set up the camera equipment for shooting the initial image and the current image according to the best shooting point.

[0073] Specifically, confirm the plane where the crack is located, start from the midpoint of the crack, extend a ray along the direction perpendicular to the plane where the crack is located, until the ray touches any support, the support can be the ground, other buildings, street lights Wait.

[0074] Use the support as a pre-shooting point, place the camera, and keep the surface of the camera parallel to the plane where the crack is located.

[0075] At the pre-shooting point, the image of the crack is taken by the camera, and it is judged whether the crack is blocked by other sundries, such as leaves, etc. If it is blocked, the pre-shooting poi...

Embodiment 2

[0141] Crack monitoring system caused by excavation displacement, refer to figure 2 ,include:

[0142] The determining means 201 determines the best shooting point according to the position of the crack, so that the monitoring personnel can set the camera equipment for shooting the initial image and the current image according to the best shooting point.

[0143] The first acquiring means 202 acquires an initial image of the crack, where the initial image at least includes a complete initial edge curve of the crack.

[0144] The second obtaining means 203 is to obtain a current image of the fracture, where the current image at least includes a complete current edge curve of the fracture.

[0145] The processing device 204 is configured to process the initial image and the current image to obtain the initial edge curve and the current edge curve.

[0146] Further, grayscale processing is performed on the initial image and the current image respectively, and the multi-pass co...

Embodiment 3

[0160] Crack monitoring device caused by foundation pit displacement, refer to image 3 ,include:

[0161] The determining module 301 determines the best shooting point according to the position of the crack, so that the monitoring personnel can set the camera equipment for shooting the initial image and the current image according to the best shooting point.

[0162] The first acquiring module 302 acquires an initial image of the crack, where the initial image at least includes a complete initial edge curve of the crack.

[0163] The second acquiring module 303 acquires a current image of the fracture, where the current image at least includes a complete current edge curve of the fracture.

[0164]The processing module 304 is configured to process the initial image and the current image to obtain the initial edge curve and the current edge curve.

[0165] Further, grayscale processing is performed on the initial image and the current image respectively, and the multi-pass c...

Abstract

The invention relates to a monitoring method, system and device for cracks caused by foundation pit displacement and a storage medium. The method comprises the following steps: acquiring an initial image of a crack, wherein the initial image at least comprises a complete initial edge curve of the crack; obtaining a current image of the crack, wherein the current image at least comprises a completecurrent edge curve of the crack; processing the initial image and the current image to obtain the initial edge curve and the current edge curve; calculating the length difference between the initialedge curve and the current edge curve according to the initial edge curve and the current edge curve; and determining whether the length difference is greater than an expansion threshold or not, and if so, sending warning information. The method has the effects of saving manpower, monitoring cracks in real time and enabling monitoring to be more convenient.

Description

technical field [0001] The present application relates to the field of disaster prevention, in particular to a crack monitoring method, system, device and storage medium caused by foundation pit displacement. Background technique [0002] Foundation pit monitoring is an important link in foundation pit engineering. It refers to various observations and analyzes of foundation pit rock and soil properties, support structure displacement, and changes in surrounding environmental conditions during foundation pit excavation and underground engineering. Work, and feedback the monitoring results in time, predict the deformation and stable state development that will be caused by further construction, and judge the degree of impact of construction on the surrounding environment according to the prediction, to guide design and construction, and realize the so-called information construction. [0003] Crack monitoring is included in the foundation pit monitoring. As the building’s ser...
