Precision Evaluation of Georobot Automatic Continuous Deformation Monitoring

Abstract:

Georobot is widely used to precision engineering measurement, especially in automatic continuous deformation monitoring, e.g. dam and landslide deformation monitoring, in virtue of the unique ATR and tracking technology. However it is hard to evaluate the actual tracking measurement precision because of the complex circumstance in specific application. The paper designs reasonable experiments solution, including test of tracking measurement of the stationary target point for the positioning precision and test of tracking measurement of the regular shape for the measuring deformation precision. The experiment result shows the positioning precision and measuring deformation precision both can reach the sub-millimeter level if centering error is eliminated, otherwise maybe in about 1.5mm level. It validates the reliability and efficiency of Georobot in automatic continuous deformation monitoring.
