Please have a prawn pointing point for the panoramic image stitching,
I am doing the splicing of panoramic images, which is to split the coincidence into small pieces, and then the grayscale comparison, to find a suture curve, but can't do seamless splicing,
Dear, if you have this experience, please talk about how to implement it.

Where is the similar software download?

There is a very good software: Pixmaker,

What forum, I sent it, he said that I didn't log in, there were so many white.

Image The brightness of the contact point should first be consistent.
If there is a displacement deviation, the coincide is stretched.

The brightness of the contact point has been adjusted, which can make two pictures under different exposure to transition,
How is the problem now find a series of contact points
For example, photographing two indoor photos, there is a beam in the coincident area, because the angle of the beam shooting is different, the beam is not necessarily parallel or just in the absence of the zone, and it is very likely that this intersection, then this intersection, how to find it ?
Also: The deviation of the coincid portion is slower, not very feasible.

I saw the discussion in another post. I don't understand your matching algorithm. Can you send me a copy of your Code?
