三维空间中的物像几何关系与计算

The geometry relationship and calculation between the object and its photograph in 3D space

根据物像正切定律导出了平面影像的 4种测算方法 ,阐述不同空间姿态下的物像形状关系 ,分别设计出了矩形、球体和圆的空间姿态图 ,推导出它们的三度坐标计算公式 ,为用计算机提供平面图像奠定了基础。

Based upon the tangent law between the object and its photograph, four calculation methods of plane image are educed, the relationship of shape is expounded between object and its photograph in different space stance, the space stance diagrams of rectangle, sphere and circularity are designed and their 3D coordinate calculation formula is educed which is the base of plane image application in computer.
