| Abstract: | The techniques of projection center finding and perspective plane determination in 3 D PIV have been investigated profoundly. A basic approach,w hich is to find out the projection center and perspective plane with some known particle positions and their spot images,has been proposed.Some related mathemat ical models have been given.Finally,the techniques have been proofed with experi mental methods. |
