3D Reconstruction - Image Matching error

Greetings, I’m having a problem with the GUI.showImageMatching function. Basically, I obtain the information of the two images in the first iteration, and then show the RGB images with GUI.showImages(imageL, imageR, True).

Once the images have been displayed, the pipeline loop starts. In the loop the homologous point is calculated, so I write GUI.showImageMatching(int(l_pt[0]), int(l_pt[1]), int(r_pt[0]), int(r_pt[1])) to see the matching in the images.

The matching is shown but for a mere fraction. I want each matching to be persistent in the image.

I attached a video showing the matching of the first 200 feature points, with the problem I refer: Image Matching - Error

Any thoughts?
