摘要: 对三维PIV中透视投影的视点定位与透视平面的确定技术作了深入的研究,提出了一种确定视点坐标与透视平面的方法,给出了相应的数学关系式,最后通过实验的方法对视点坐标与透视平面的确定技术进行了检验。Abstract: The techniques of projection center finding and perspective plane determination in 3-D PIV have been investigated profoundly. A basic approach,which is to find out the projection center and perspective plane with some known particle positions and their spot images, has been proposed. Some related mathematical models have been given. Finally, the techniques have been proofed with experimental methods.
