Butterfly-shaped mark point soft rock foundation surface deformation monitoring system and device based on binocular vision
The invention relates to the technical field of foundation deformation monitoring, in particular to a butterfly-shaped mark point soft rock foundation surface deformation monitoring system and devicebased on binocular vision. Each butterfly-shaped mark point is composed of two mirror image gradual change right-angled triangles with the same size. The soft rock foundation surface deformation monitoring system comprises butterfly-shaped mark point setting, image acquisition, camera calibration, coordinate calculation and three-dimensional matching. The soft rock foundation surface deformation monitoring device comprises a vertical support, a main beam with a groove, a main beam without a groove, an auxiliary beam with a hollow clamping groove, a binocular camera assembly and a displacementmeter assembly. The butterfly-shaped mark point soft rock foundation surface deformation monitoring system and the device based on binocular vision are provided through utilizing the self-defined butterfly-shaped mark points and an improved mark point center three-dimensional coordinate calculation method, and real-time monitoring of soft rock foundation deformation is realized at low cost.
本发明涉及地基变形监测技术领域的一种基于双目视觉的蝴蝶形标志点软岩地基表面变形监测系统和装置。蝴蝶形标志点由两个尺寸一致的镜像渐变直角三角形组成。软岩地基表面变形监测系统包括蝴蝶形标志点设置、图像采集、相机标定、坐标解算、立体匹配。软岩地基表面变形监测装置包括竖向支架、带凹槽的主梁、不带凹槽的主梁、带镂空卡槽的副梁、双目相机组件和位移计组件。本发明通过自定义蝴蝶形标志点和改进的标志点中心三维坐标解算方法，提出了一种基于双目视觉的蝴蝶形标志点软岩地基表面变形监测系统和装置，在低成本上，实现了对软岩地基变形的实时监测。
