how to get Homography matrix?

[steve13durant]

I found the test result is pts2_pred value, how can I predict Homography matrix with two frames?

You can refer to this function:
pred_h4p, _, not_found = ransac_h.find_homography(I_sample, I_prime_sample, pts_1, pts_2, visual=args.visual, method=args.method, min_match_count=args.num_features)
Where pts_2 = pts_1 + pts2_pred
