Hello All. This is my first time using OpenCV.

I have managed to stitch together a series of photos. What I would like to do is take photos of the same spot tomorrow, stitch them together, and then see if anything has changed from one day to the next.

Is this possible or am I getting ahead of myself.

That is perfectly possible if you try some basic operations

  1. After creating both panoramas, align them first by matching interesting keypoints
  2. Apply a histogram equilization to counter for some of lighting variance
  3. Apply some sort of background subtraction algorithm between both images
  4. Use some morphological operations to keep only the largest changes!
