Evaluation of Ground Positioning Accuracy for Domestic Airborne Dual-Frequency LiDAR
Based on the localization model of domestic airborne dual-frequency LiDAR system, various factors that affect the positioning accuracy are analyzed, and the comprehensive accuracy evaluation model of the system is deduced by the error propagation law. According to the sensor parameters of the system, a simulated calculation is made for its theoretical positioning accuracy. The method of airborne radar's location accuracy assessment is analyzed for reference, through which a method to evaluate the accuracy of ground location based on planar features is designed. By using the airfield data and high precision control data to carry out the accuracy evaluation, the thesis gets the result that the accuracy of the domestic airborne dual-frequency LiDAR system meets the design requirement and the evaluation method is simple and feasible.
