| 摘 要： | 建立了锥面包络螺旋面上影象法成象点的数学模型,证明了锥面包络螺旋面上的影象法成象点具有极高精度的共面性,定量分析了由于成象点不能同时共处于瞄准平面上而引入的原理误差及其表现形式,并且指出螺旋面上影象法成象点所具有的共面性在消除上述原理误差的研究中的重要意义。

| Abstract: | The mathematical model of boundary object points on the type-ZK helicoid in silhouette method is established. From this, the regularity and the value of methodology errors existed in traditional silhouette method are calculated and analysed, when the helicoid parameters are measured. The behaviour of common-plane of boundary object points on type-ZK helicoid is demonstrated and the significance of this behaviour is explained. |
