Abstract

The angle-based intersection measurement system is a high-precision overall measurement network based on the perspective observation in space. However, when the target is moving, the angular intersection failure will cause dynamic error to limit its application in the field of dynamic measurement. Aiming at this problem, Firstly, this paper analyze the sources of dynamic error from the principle, studies the influencing factors of system dynamic error include :the motion state of the measured object, station deployment. Secondly, constructs a mathematical model to predict the dynamic error of the measurement system. Finally, design some simulation experiments to quantify the measurement dynamic error at different measure conditions. The results show that under the measurement conditions of the measurement area is 10m x 10m x 1m, observation angle uncertainty is 2′′, the measured target moves at 0.05m/s, the average dynamic error of the measured area under the 0_4 deployment is the minimum, and value is 0.25mm.
