Foundation pit displacement monitoring method based on machine vision
The invention provides a foundation pit displacement monitoring method based on machine vision, and the method comprises the following steps: S1), deploying a reference target and a monitoring target which are composed of checkerboard targets at a settlement monitoring point at the periphery of a foundation pit, and assembling image collection units which form a plurality of preset positions during working; s2) acquiring real-time image information acquired by an image acquisition unit, and identifying feature points on the checkerboard; and S3) processing the feature points on the checkboard so as to obtain the displacement changes of the monitoring target in different time periods. According to the method, required equipment is simplified, and only a single camera, a monitoring box and some markers are used, so that the high cost of multiple sensors and professional instruments in a traditional monitoring system is greatly reduced.
本发明提供了基于机器视觉的基坑位移监测方法，包括以下步骤，S1)于基坑外周沉降监测点处，分别部署棋盘格靶标构成的基准靶标和监测靶标，并装配工作时形成若干个预置位的图像采集单元；S2）获取图像采集单元采集的实时图像信息，并识别棋盘格上的特征点；S3）处理所述棋格盘上的特征点，进而获得监测靶标在不同时间段的位移变化。本发明通过简化所需设备，仅使用单一相机和监控箱以及一些标志物，大幅度降低了传统监测系统中多传感器和专业仪器的高昂成本。
