Will it affect my result if I perform my camera calibration and image processing at different resolutions?

I did the stereoscopic camera calibration for checker board image with a resolution of 640x360. But, my images are of resolution 800x480. I am trying to find the 3D world co-ordinates using stereo triangulation, this will affect the result right?

Yes it will. There is a way to transform the camera parameters to account for the change in resolution, but you are much better off re-calibrating with the same resolution that you are actually going to use. Take a look at this example in the Computer Vision System Toolbox.
