针对双灭点条件下纠正大倾角近景影像算法的不足,提出了基于灭点理论、空间直线几何补偿联合广义点(直线)摄影测量光束法平差的建筑物影像自动纠正算法。实验结果表明,改进算法具有一定效果。
The presented algorithm of rectifying big oblique angle image based on vanishing point geometry and the geometric constrains of parallel object lines,has a deficiency,because usually only two vanishing points can be detected in many building images,which leads to lack restriction of vanishing point in depth orientation(Z).In order to overcome this problem caused by the degree of freedom in Z orientation,on the basis of bundle block adjustment of generalized point photogrammetry theory combining with space lines geometric compensation(Z direction),a novel solution method is proposed.The experimental results indicate that our improved algorithm is better than previously reported approach.
