摘要
激光雷达和CCD摄像机各自都具有快速获取物体空间信息的能力，广泛应用在真实场景的三维建模中。激光雷达与CCD摄像机数据融合面临的首要问题是二者之间坐标系的标定，针对脉冲激光雷达和CCD的特点设计了一种三维标定靶，提出了一种改进的外部标定算法，利用主成分分析法拟合平面，提高了标定精度。将激光雷达和CCD标定算法运用在物体三维建模中，研究了基于外部标定算法的三维重建和纹理映射，取得了较好效果。
Abstract
Ladar and CCD camera have the excellent ability of capturing 3D information of objects, and they are widely used in 3D modeling. The major problem of the fusion of ladar data and CCD camera data is the coordinates calibration between them. In consideration of the traits of ladar and CCD camera, a special 3D calibration object is designed, and an improved coordinates calibration method is proposed, which fits a plane by using principal components analysis and can highly improve the calibration precision. The improved coordinates calibration method is applied on the 3D reconstruction and texture mapping. Experiment results show that our algorithm gives good result in texture mapping.
