平面型场景图像的层次化三维度量重建

Stratified 3D metric reconstruction of plane image

主要对平面型场景图像的三维度量重建方法进行详细的研究阐释,提出了层次化的平面型场景图像三维度量重建方法。该方法不必对摄像机定标,首先根据平行线来计算图像平面的消失线得到仿射重建,然后在仿射平面上利用直线之间的已知相对长度、已知角度和相等未知角来计算圆点得到度量重建。

Detailed studies on the 3- dimensional metric reconstruction of plane scene image are conducted. A stratified 3 - dimensional metric reconstruction method of plane scene image is presented. Instead of the adoption of camera calibration, the vanishing line in image plane is computed by means of parallel lines to obtain the affine reconstruction, the circular points in affine plane are computed using known relative lengths, known angles and equal unknown angles to implement the metric reconstruction.
