Abstract:

为了对标记点丢失的多幅自标定图像进行精确重建,提出了一种基于标记点丢失的多幅自标定图像的3维重建和相机姿态恢复的方法。该方法与原来方法的不同之处在于,该方法是利用标记点(编码点和非编码点)的方式,即用编码点进行单CCD相机的自标定和姿态恢复,而用非编码点进行3维点的3维重建。该方法有以下3个主要特点:(1)由于该方法采用了标记点的自动识别匹配,所以避免了手工交互选择图像点对(pointcorrespondences)费工费时的问题;(2)由于标记点匹配精确,提高了3维点的重建精度,故符合工程要求;(3)由于噪音对标记点的像点影响较小,因此该方法比以前的方法具有更好的鲁棒性。实验结果表明,利用该方法产生的3维重建点精确可靠,能够满足逆向工程等应用的要求。
