长久以来灭点的研究都集中在自动检测和相机检校方面,然而对其本身的误差分布研究并不多。针对直线交会灭点时存在的闭合差问题和灭点的误差分布问题,进行深入探讨。构建单像灭点平差解算的初始选权方案,并提出基于选权迭代法、协因数矩阵和误差椭圆理论来解算和估计灭点误差分布的方法。通过实验揭示灭点误差分布规律。 更多还原

【Abstract】 The related researches of vanishing point have been focusing on its automatic detection and camera calibration for a long time,however there were few researches on its error distribution.Aiming at the closing error issue of lines intersection and the error distribution of vanishing points,we have made in-depth discussions.How to set initial weights for the adjustment solution of single image vanishing points is presented.Furthermore,we propose solving and estimating error distribution of vanishi... 更多还原
