摘要
根据研究物体本身形态及其运动状态的需要，从摄影原理出发，对同一空间物点，通过两次照相，详细地研究了空间物点的各空间直角坐标与照相机焦距、拍照平移距离及两次拍照的相坐标差之间的关系，从而导出了物点的空间直角坐标公式及空间物点到测点的距离公式；同时应用空间解析几何基本理论。
According to the reguirements of researching material object's morphological shape and motional state,following the photograph principle,through the twice shooting of the same spatial point,the relationship between the spacial rectangular coordinates of space object and camera focal length is studied in detail;between photo translating distance and the difference of twice phase coordinates.As a result,the distance formula of spatial points to the measuring points and rectangular coordinate formula are arrived at.Meanwhile,on the basis of spatial analytical geometry elemental theory,the formula of included angle between the surface central normal line of spatial object and camera principal optic axis is presented.
