Ship-borne 3D laser scanning technology has vital theoretical significance and practical value in marine surveying and mapping.As one of the key steps of ship-borne 3D laser scanning, calibration of mounted parameter is urgent to be solved.This paper proposes a calibration method of mounted parameter without control points for ship-borne 3D laser scanning system.Based on the corresponding points in overlapping area, mounted parameter calibration model of scan system is built by time and spatia registration model of ship-borne 3D laser scanning data.Finally, differential least squares are applied to obtain optimum mounted parameters.Experiments demonstrate the reasonable and effectiveness of this method,the quality of scanning data can be significantly improved.
