Problems solved by technology
In addition, due to the high proportion of manual participation in the monitoring of tunnel entrances and slopes by traditional methods, under this condition, the measurement frequency is limited, and the number of selected monitoring locations for tunnel entrances and surrounding slopes is often limited. It is also difficult to effectively control the existing errors

Description
technical field [0001] The invention relates to the field of tunnel safety monitoring, in particular to a computer vision-based monitoring system and method for slope deformation of a tunnel entrance. Background technique [0002] At present, in the whole process of tunnel construction, the monitoring measures adopted are to use traditional methods (such as level, theodolite, total station, etc.) to select appropriate reference points inside and outside the tunnel as the tunnel construction progresses. Terrain GPS receiving device or other conventional surveying and mapping means, calibrate the position and elevation of the measuring points, and then use traditional instrument methods to measure the changes of the tunnel entrance and surrounding slopes and surface at the calibrated measuring points, and the reference points in the cave The position and elevation can be measured based on reference points outside the cave, and used as observation points for settlement and defo...
