An Algorithm of Building Image Rectification with Generalized Point Photogrammetry and Object Space Compensation

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.
