3D world coordinates from stereo calibration

I want to get a 3D world coordinate of a point in an image from its pixel coordinate. For this, I have studied that we need extrinsic and intrinsic parameters of a stereo setup. Now, I have successfully done the stereo calibration. I have set two same cameras 14 cm apart and prepare a stereo setup. ...

Re: Stereo_Camera Calibration error

Thankyou stereomaton and realizator for your quick response. Realizator: I have seen the zip file you have shared in that thread which you mentioned here.. and I have created the point cloud but I have not get what exactly I want. I just need exact 3D coordinates of one specific point in image using...

Re: Stereo_Camera Calibration error

Thankyou Stereomaton, I have successfully done the stereo calibration. I have set two same cameras 14 cm apart and prepare a stereo setup. I have followed this code up to 4_fisheye_calibration.py. I have calibrated and obtain RMS of 1.5. Now I just want to find the 3D world coordinates of any specif...

Re: Stereo_Camera Calibration error

Hello I am new to camera calibration. I was using this code for stereo calibration to calibrate a single (left) camera only. I have comment out all the code lines for stereo and right camera calibration. It works to recognize corners of chessboard but it gives this error when proceed to left camera ...
