Abstract
本发明公开一种单目视觉方钢管混凝土柱三面检测装置,包括用于放置方钢管混凝土柱工件的工作台,远离工作台的前方放置有朝向工件且用于检测工件的检测模块,检测模块与计算机电连接,工作台顶面设置带有镜面且用于反射工件左右侧面的镜面反射模块,工件朝向镜面反射模块的左侧面和右侧面均粘贴有白纸。本发明还提出一种检测方法,实现对工件正面和两个侧面进行裂纹检测。本发明技术方案的镜面反射机构能够实现镜面水平方向的旋转与平移以及竖直方向的旋转与平移,实现镜面角度与成像范围的微调,可适用于各种不同的实验环境,同时本发明只使用一台相机即可同时检测到工件正面和两侧表面共三个表面裂纹情况,具有成本低,效率高,操作方便等特点。
The invention discloses a monocular vision detection device for three sides of a square steel tube concrete column, comprising a worktable for placing a square steel tube concrete column workpiece, a detection module facing the workpiece and used for detecting the workpiece is placed in the front away from the worktable, and the detection module is connected with the workpiece. The computer is electrically connected, and the top surface of the worktable is provided with a mirror reflection module with a mirror surface for reflecting the left and right sides of the workpiece. The left and right sides of the workpiece facing the mirror reflection module are pasted with white paper. The invention also provides a detection method, which realizes crack detection on the front surface and two side surfaces of the workpiece. The mirror surface reflection mechanism of the technical solution of the present invention can realize the rotation and translation of the mirror surface in the horizontal direction and the rotation and translation in the vertical direction, realize the fine adjustment of the mirror surface angle and the imaging range, and can be suitable for various experimental environments. One camera can simultaneously detect three surface cracks on the front and both sides of the workpiece, which has the characteristics of low cost, high efficiency and convenient operation.
