Foundation pit deformation monitoring method and system based on machine vision
The invention relates to the technical field of foundation pit monitoring, and provides a foundation pit deformation monitoring method and system based on machine vision, and the method comprises the following steps: system layout: arranging a target vertical rod at a feature point position of a foundation pit, and arranging a reference point vertical rod at a reference point position of the foundation pit; the problem of system view shielding is solved; resolving the real-time pose of the binocular monitoring host by using a positioning camera to obtain the pose information of the host; primarily calculating the displacement of the main target by using a binocular monitoring host to obtain displacement data of the foundation pit; and correcting the displacement data of the foundation pit by utilizing the position and posture information of the host and the displacement of the positioning target calculated by the binocular monitoring host. The problem of pose disturbance of the binocular monitoring host is solved through the positioning camera, and the problem of deviation between the displacement of the main target and the actual displacement of the foundation pit is solved by arranging the main target and the positioning target on the target vertical rod regarded as a rigid body. According to the method and the system, the monitoring precision and stability are improved, the monitoring difficulty is reduced, the automation degree is high, and the method and the system have better application prospects.
本申请涉及基坑监测技术领域，提供了基于机器视觉的基坑变形监测方法与系统，包括以下步骤：系统布设，将靶标立杆设置在基坑的特征点位置，将基准点立杆设置在基坑的基准点位置；解决系统视野遮挡问题；利用定位相机解算双目监测主机的实时位姿，以获得主机位姿信息；利用双目监测主机初步计算主靶标位移，以获得基坑位移数据；利用主机位姿信息和双目监测主机计算的定位靶标位移修正基坑位移数据。本发明通过定位相机解决双目监测主机位姿扰动问题，通过在视为刚体的靶标立杆上设置主靶标和定位靶标，解决主靶标位移与实际基坑位移偏差的问题。该方法与系统，提高了监测精度、稳定性，降低了监测难度，自动化程度高，具有较好的应用前景。
