achiving 3D camera possition

[armosh]

Hello world,

I need to achieve 3D camera possition in other words (x,y,z) coordinates of camera. Is it possible using a grid of dots (grid distances are known) ? If not, may be it is possible with one known coordinate?

I'm not good in projective geometry shoud I read some articles about it or it does not help me?

Thanks,

Aleks.

armosh,

Can you explain your question in more detail. If I understand it correctly you are trying to calibrate for 3D/2D image processing. Well honestly I do not have much experience in 3D yet, specially using NI Products. But I have done quite a few applications that used NI Vision and motion technologies. The 2D calibration VIs that come with NI Vision are very good for most part. It also depends on how big of an area you are trying to calibrate because it will dictate the accuracy of the camera mounting & calibration grid used.

Are you also thinking about moving the camera giving it 6DOF (degree of freedom three linear axis and 3 rotational)?
