How to show the place of origin place of the images via openCV image stitching function?

Such as there are three images called (1st,2nd,3rd) and after image stitching I get a completed photo which consists in the order of (1st 3rd 2nd). Then I wonder how to get this order (1st 3rd 2nd)?

(Maybe they are in the same size such as 400*300 and I wonder if OpenCV could do that cause I'm going to process hundreds of images and I couldn't recognize these hundreds of images one by one using my eyes)

You can get the order (and some other infos) of the stitched images with cv.detail.matchesGraphAsString -> docs

graph matches_graph{
"weir_1.jpg" -- "weir_2.jpg"[label="Nm=157, Ni=135, C=2.45009"];
"weir_2.jpg" -- "weir_3.jpg"[label="Nm=89, Ni=70, C=2.01729"];
"weir_noise.jpg";
}

enter image description here
