【摘要】 使用两部JVC摄像机对爱捷008-D辐射式框架进行定点拍摄,运用直接线性转移 (DLT)方法进行标定框架的三维重构和精度分析。结果表明:辐射式框架的控制点数目足够多且在标定空间内均匀分布时,如果控制点张成空间大于并包含被标定对象,可以达到比较好的标定精度;如果控制点均匀地分布于被标定对象的内侧和外侧,可以达到的标定精度更好。

【Abstract】 Two JVC video cameras were used to shoot the Ai-jie 008-D Radiate Frames at the fixed points. By the method of DLT, three-dimensional reconstruction and accuracy analysis were made on the targeted Frame. The result shows that when the control points of the Frame are sufficient and well-distributed in the targeted space, the better targeted accuracy can be obtained if the space of the control points is bigger than the targeted object and embraces it. If the control points are well-distributed on the inside and outside of the object, the targeted accuracy obtained can be even better.
