Sequential image stitching

edit

I think that is how the stitch function works. In order to stitch the images, the one on the left loses resolution. Thus since your sequence is stitched in a loop, the blur at each step keeps increasing.

There is a way to manually stitch images. You need to calculate the homography matrix between the two images and then based on that use the warpPerspective function to stitch the images. However, I am not sure that this would solve your blur problem. Take a look at this tutorial. It might be useful -> ramsrigoutham.com/2012/11/22/panorama-image-stitching-in-opencv/

Person with a difficult name: I used the simple stitch example and added this loop.
Potato: Thank you, I'll try that!

This tutorial didn't even stitch my images =( I'll try to change some parameters

Like being said it is to reduce noise to yield keypoints. I guess you will need to use masks to reduce this effect. Basically you take the left 10% of image one and the right 10% of image two and only merge based on those regions. This will reduce the blurring effect you are experiencing.

yea, I thought about that, because resolution is very important to my application. Do you think it works by using this function below and use the R.O.I. for the 10% of the image?

C++: Status Stitcher::stitch(InputArray images, const std::vector<std::vector<Rect>>& rois, OutputArray pano)
Parameters: 
images – Input images.
rois – Region of interest rectangles.
pano – Final pano.

Yeah that should do the trick!

how do I specify this ROI? I'm struggling at it.

    Rect left = cvRect(0, 0, imgs[i].cols*0.2, imgs[i].rows);
    vector<Rect> vLeft;
    vLeft.push_back(left);
    roiStitch.push_back(vLeft);
    //right rect
    Rect right = cvRect(imgs[i].cols*0.2, 0, imgs[i].cols*0.2, imgs[i].rows);
    vector<Rect> vRight;
    vRight.push_back(right);
    roiStitch.push_back(vRight);

I'm creating rectangles of the size I want. Cool. But, how does the stitch function knows that the rectangle of that size goes on the right and left sides of the image?

I am sorry but I have no programming experience with the stitcher pipeline. Should wait for someone else.

ok thanks, but the issue is only to create a ROI of the type "vector<vector <rect=""> >& rois".
