The invention discloses an algorithm for ensuring visual guidance precision, and relates to the technical field of tunnel deformation repair, and the algorithm comprises the following steps: S1, camera shooting; s2, splicing the images; s3, point cloud rough matching; s4, point cloud precise matching; and S5, extracting coordinate information. In order to realize intelligent construction of a steel plate grabbing link in steel ring reinforcement, a visual guidance technology is used, and in order to guarantee visual guidance precision and algorithm processing efficiency, visual guidance mainly depends on a 3D camera to shoot a target object to obtain plane information and depth information of the target object, three-dimensional point cloud data of the target object is obtained through software processing, and based on the data, a three-dimensional point cloud model of the target object is obtained. Firstly, rough matching needs to be conducted on the point cloud data, the point cloud data of a captured targe
