But always remind me of program errors.

`_Traceback (most recent call last): File "D:/CHENGXU/aerial-image-stitching-master/aerial-image-stitching-master/image_stitching.py", line 203, in result = stitch(result,cv2.imread(img_list[i],cv2.IMREAD_GRAYSCALE))

how to run it?

Hi, It says singular matrix while trying to calculate the inverse. You could try replacing H = np.linalg.inv(np.matmul(A.transpose(), A)) with H = np.linalg.pinv(np.matmul(A.transpose(), A)). But I would recommend using another image set to test the code first, or try playing around with the SIFT parameters.
