[Abstract]:The object of this paper is vehicle photogrammetry system. The main topic of this paper is to discuss the method of evaluating the positioning and attitude determination accuracy of POS in vehicle photogrammetry system by using high precision laser tracker. This paper introduces the development of mobile measurement system, the principle of measurement and the coordinate system involved, and deduces the adjustment process of coordinate system transformation using a new mathematical model. A method to calibrate the positioning accuracy of POS with laser tracker is proposed and its effect is verified. The main work is as follows: 1. The development history and research status of mobile measurement system are introduced, the structure of mobile measurement system and its measuring principle are introduced. This paper summarizes the four main coordinate systems and their conversion relations involved in the vehicle photogrammetry system. 2. In order to meet the requirements of rapid coordinate transformation, a rotation matrix formed by the rotation axis vector and the rotation angle is used to rotate the coordinate system. On this basis, a coordinate transformation model of eight parameters is proposed, and the process of solving the transformation model of coordinate system based on the common point pair adjustment is given, and it is verified that the method has less iteration times. The accuracy is the same as the traditional method. 3. A method for evaluating the positioning accuracy of POS by laser tracker is proposed. When the POS of the vehicle photogrammetry system works normally, when the vehicle is parked at different positions and positions, the six points fixed on the vehicle are measured by laser tracker, and their WGS84 coordinates are obtained. It is used to evaluate the positioning and attitude accuracy of POS. 4. To evaluate the position and attitude accuracy of POS output from two aspects. Firstly, the WGS84 coordinates are calculated from the POS carrier coordinates of the fixed points and the position and attitude of the POS outputs, and the positioning accuracy of POS is evaluated by the difference between the WGS84 coordinates measured by the laser tracker and the WGS84 coordinates measured by the laser tracker. Then the WGS84 coordinates measured by the laser tracker and the POS carrier coordinates of the fixed point are used to calculate the position attitude of the loaded vehicle and to evaluate the position attitude accuracy of the POS output by the difference between the position attitude of the vehicle and the position attitude of the POS output. Finally, the two methods are analyzed and compared with the existing evaluation results.
