Abstract: The objectives of this research are to simulate LiDAR system calibration and to analyze the calibration effect in different conditions. The random and systematic errors impact of the airborne laser scanner (ALS) on derived point cloud is investigated in terms of LiDAR strip configuration (flight altitude, direction and scan angle). An analysis method has been proposed to analyze the calibration effect of every calibration parameters of the calibration using discrepancies between overlapping strips. This method analyzes the calibration effect of system parameters by the standard deviation changing of the system parameter biases solution. Three data types (point, line and surface) are considered in this analysis method. Control and conjugate datasets of cach data type are both analyzed. This method can help users analyze the calibration effect before a calibration procedure implementing and improve the flight plan. An application has been developed in Matlab software environment to simulate the calibration procedure and analyze the calibration effect by using proposed analysis method. The application can simulate calibration in three modes (control, cross and opposite) corresponding using control data, overlapping strips flown in cross direction flight plan and opposite direction flight plan. Advanced function has been developed to simulate complex flight plan with a drawback that users need to consider the availability of the simulated flight plan. Some simulation situations were implemented to analyze the relationship between flight plan and calibration effect. In addition, several recommendations for calibration flight plan were provided.
