摘要/Abstract

摘要： 船载三维激光扫描技术在海洋测绘中具有重要的理论意义和实用价值。安置参数标定作为船载三维激光扫描系统测量的重要步骤，是当前亟待解决的问题。本文提出了一种无地面控制点的船载三维激光扫描系统安置参数标定方法。该方法在船载三维激光扫描数据时空配准模型的基础上，根据扫描测线重叠区域内的同名特征点，推导扫描系统安置参数标定模型，最后采用差分最小二乘算法求解参数最优值。试验验证了本文方法的合理性和有效性，能够显著提高扫描数据的质量。

Abstract: 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.

Key words: ship-borne 3D laser scanning, mounted parameter calibration, time and spatial registration, corresponding points, difference least square
