摘要
考虑到相机安置角一般为微小角度的情况,本文结合机载LiDAR数据和同机高精度影像,基于连接点的自动提取和虚拟地面控制点,建立安置角计算模型,完成在没有控制点的情况下,机载LiDAR系统的相机安置角的检校。该方法不需要地面控制点,较传统方法更加灵活。
Boresight misalignment between the CCD camera and IMU is general slight angles.On the basis of the feature point extraction and coordinate calculation method,it proposes a new automatic method for boresight misalignment calibration which is one component of an airborne light detection and ranging（Li DAR） system without ground control points（GCPs）.The proposed method without GCPs is more flexible than other traditional ways.
