I have two camera's lets say A and B. Camera B is mounted slightly above (say 20 cm for example) camera A and has a slightly different angle then camera A.
Now I want too take a picture with both camera's and draw a point at exact the same location on both images. I need to somehow calibrate the images so when I draw a point at lets say (100, 100) on the image from camera A I end op at the same location on camera B.
For this to work I need to detect (find) the deviation from lets say camera A to camera B. With this deviation I can then translate points from camera A to camera B. I have done some research and found something called Stereo Reflection but this seems not of any use because it tries to find x, y, z, positions of points in 3D space. I only need to translate 2D coordinates from one image to another.
I am a beginner with openCv but I know this must be possible using openCv but I don't know where to start. Can any one point me to the right direction?
It seems that you are looking for image registration.
