The method comprises the following steps: obtaining monitored basic data of the open mine pit slope, which is acquired by the measurement robot; establishing a model of a height difference between a distance measuring optical path curve of the measurement robot and the ground, and an atmosphere vertical refraction physical quantity gradient model on a distance measuring optical path; obtaining an instrument height and a beacon height of the measurement robot; calculating the height difference from a monitoring base point subjected to atmosphere refraction revising and a monitoring point according to an included angle, a slope distance and a horizontal distance from the monitoring base point to the monitoring point, an atmosphere refraction coefficient on the distance measuring optical path curve and the instrument height and the beacon height of the measurement robot; obtaining an elevation of the revised monitoring point according to the height of the monitoring base point, measured by the measurement robot, and the height difference between the monitoring base point subjected to atmosphere refraction revising and the monitoring point. The elevation data is processed by utilizing the method provided by the invention, the precision of the elevation data can be relatively greatly improved and the reliability of a monitoring result is improved, so that a foundation is laid for real-time early warning of landslip of the open mine pit slope.

Description

technical field [0001] The invention belongs to the technical field of slope engineering deformation monitoring, and in particular relates to a processing method for monitoring elevation data of an open-pit mine slope based on a measuring robot. Background technique [0002] After a long period of mining in open-pit mines, the mining depth has been continuously deepened, and the length of the slope has been continuously lengthened. Many mines are already in the process of deep concave mining. Therefore, landslide accidents occur frequently in open-pit mines, which pose a great threat to the safe production of open-pit mines. In order to solve the problem of slope safety in open-pit mines, scholars at home and abroad have been working on the analysis and prediction of slope instability for many years. Slope monitoring data is an important data source for slope instability analysis and prediction. As a result, the accuracy of elevation data collected by the high-precision to...

AI Technical Summary

Problems solved by technology

[0003] However, the current research status has the following problems: ① The modeling method reflects the separation of theory and practice

②The research on the law of the physical quantity of each atmospheric refraction factor changing with the altitude is not deep enough

③ The inverted atmospheric refraction coefficient model does not have matching conditions, so it lacks practicability

In view of the above reasons, the atmospheric refraction correction based on the measuring robot in the open-pit mine environment generally adopts the empirical model, but because the empirical model does not match the applicable conditions, the accuracy of the triangular elevation data obtained from this is poor
