轴测投影的原形及刚体运动参数的计算

THE ORIGINAL SHAPE OF AN AXONOMETRICAL PROJECTIONAL FIGURE AND CALCULATION OF THE KINEMATIC PARAMETERS FOR A RIGIED BODY

由投影恢复其原形是投影理论的基本问题之一,也是计算机视觉的基本问题。本文首先研究了在斜投影下刚体复原的问题,提出恢复原形的充要条件。在此基础上利用刚体在同一时刻的两个投影而恢复其空间位置及结构,进而计算刚体在两位置之间的运动参数。

To reconstruct the original shape of a body from its projections is one of the essential problem in the projection theory,and also in computer vision.In this paper the reconstruction of a rigid body from its obligue projections was studied and sufficient and necessary conditions were established.Kinematic parameters for the body moving to anarbitrarily position were also calculated.
