Foundation pit deformation intelligent monitoring method and system
The invention discloses an intelligent monitoring method and system for deformation of a foundation pit, and the method comprises the following steps: S1, arranging a small number of network video monitoring cameras outside a settlement influence range at the periphery of the foundation pit according to the size and shape of the foundation pit, and taking pictures of deformation of the foundation pit; s2, after each camera is erected, taking an initial picture as an original reference, and independently transmitting the initial picture to a server for storage through a wireless network; and S3, in the foundation pit monitoring process, according to monitoring needs, each monitoring camera shoots a foundation pit deformation process picture at regular intervals, and independently transmits the picture to the server for storage through the wireless network. According to the method, the pictures of the same part of the foundation pit at different moments are compared and calculated through related search, an integer pixel search algorithm and a sub-pixel interpolation algorithm on a server, the displacement of image pixel points between the different pictures is obtained, and the displacement of the pixel points between the pictures is converted into actual deformation of the foundation pit through a conversion coefficient.
本发明公开了一种基坑变形智能监测方法与系统，包括以下步骤：S1：根据基坑大小和形状，在基坑周边沉降影响范围以外布置少量网络视频监控摄像头，用于拍摄基坑变形照片；S2：各摄像头在架设好后，分别拍摄一张初始照片作为原始参照，并独立通过无线网络传输到服务器进行存储；S3：在基坑监测过程中，根据监测需要，各监控摄像头定期拍摄基坑变形过程照片，并独立通过无线网络传输到服务器进行存储。本发明通过服务器上的相关搜索、整像素搜索算法、亚像素插值算法对基坑同一部位不同时刻的照片进行对比计算，得出不同照片之间图像像素点的位移，并用转换系数把照片之间的像素点位移转换成基坑实际变形。
