2014-03-20 09:52:54 -0500 asked a question How to calculate the position of the camera from an image

I have four traingles placed on the corners of an A0 page. Using openCV I have been able to calibrate the camera, through that i have got the distortion and intrinsic files saved. I have been able to detect the triangles using cvblobs or could do it using contours. But what I have to do now is to find the position of the camera so that I could figure out the ideal position to recognize the triangles. I don't know how to do the calculation and to code it. If anyone could please provide the steps in how to carry out and possibly example codes in c++, it would be great.

Thank you in advance.

see when you mean by spherical distortion... I could use the check board calibration provided by opencv.. Do you have any examples you have done before that i could refer too.

i am using a raspberry pi camera... i have four triangles on a A0 page as the reference points. I know the center coordinates of the triangle. so what would be the method I could use to find the location.

Hi,

I am new to opencv. For my project i am trying to find a way to find the location of the camera (x and y). If I could figure out the locations then it will be possible to figure out which is the best position to capture images to detect the reference point.

Please help me with it. If anyone needs more information please do not hestitate to ask. Thank you in advance.
