摘要
直接线性变换(DLT)算法是利用平面图像进行三维重构的基本算法,本文从框架位置的角度对三维重构的影响进行讨论,由此得出各个框架位置下控制点的平均相对误差,结果表明框架位置对三维重构具有一定的影响,同时相机角度对三雏重构具有深远的意义。
DLT (Direct Linear Transformation) algorithm is widely used in 3-D reconstruction of planar images. The authors tried to find out the influence of frame-position on the accuracy of 3-D coordinate reconstruction and gained the average relative error on control points from each frame- position. The result shows frame-position has some influence on the accuracy of 3-D coordinate reconstruction and the angles of camera have a great influence upon the accuracy of 3-D reconstruction.
