摘要：

A measurement system based on dynamic target tracking with laser-electronic theodolites is represented in order to realize automatic spatial measurement for moving targets in large scale. The structure of the measurement system which consists of external scanning equipment and laser-electronic theodolite is proposed. The measurement model of the video camera is established by coordinate system transformation from axis to axis subsequently. Then guidance method for the theodolites using the optical axis strategy is discussed. As the track of moving targets such as industrial robot is estimated with extended Kalman filtering process, the measuring process can be realized after the targets located in the very field of the camera at last. The experimental data show that automation level and accuracy for dynamic measurement could be improved effectively with the system, no matter which style of the moving target is to be measured.
