3d example code opencv
The final step of calibration is to pass the 3D points in world coordinates and their 2D locations in all images to OpenCVs calibrateCamera method. Multiple object detection example Installing the libraries i Installing OpenCV.

. Build3dmodel -i intrinsics_filenameyml -d detector -de. Number of plan row and column in three dimensional Mat can be found using this code. To get histogram value at a specific location we use cvMatat int i0int i1 int i2.
The line command of this code example requires the following parameters. I think you want the Q matrix to reconstruct the 3D. Google Summer of Code.
We install the opencv-contrib-python library for our purpose. These features make visualizing 3D data on OpenCV easier than ever. For example if we want to show a red cube at coordinates 5 5 5 we can write.
You can have Q matrix from stereo rectification via openCV method.
