Question

我正在尝试从图像集中制作全景图。我正在使用Spyder，OpenCV 3.4和Python 3.7。这是代码：

主要内容：
```
s/[0-9]\{10\}/abc&/g
```

缝线中的针迹.py：

from stitches import Stitcher
#from PIL import Image
import os
import glob
import numpy as np
import imutils
import cv2

cap = cv2.VideoCapture('C:/Users/VID_20181208_111037881.mp4')

img_dir = "C:/Users/user/images"
data_path = os.path.join(img_dir, '*g')
files = glob.glob(data_path)
args = []

for f1 in files:
    img = cv2.imread(f1)
    args.append(img)

def retImg(img):
    return img

for i in args:

    j = i+1

    frame = retImg(i)
    frame2 = retImg(j)

    #imageA = cv2.imread(frame)
    #imageB = cv2.imread(frame2)
    imageA = imutils.resize(frame, width=400)
    imageB = imutils.resize(frame2, width=400)

    # stitch the images together to create a panorama
    stitcher = Stitcher()
    (result, vis) = stitcher.stitch([imageA, imageB], showMatches=False)

    frame = result

    # show the images
cv2.imshow("Keypoint Matches", vis)
cv2.imshow("Result", result)
cv2.waitKey(0)

当我编译它时，显示以下错误：

def stitch(self, images, ratio=0.75, reprojThresh=4.0, showMatches=False):
# unpack the images, then detect keypoints and extract
# local invariant descriptors from them
(imageB, imageA) = images
(kpsA, featuresA) = self.detectAndDescribe(imageA)
(kpsB, featuresB) = self.detectAndDescribe(imageB)

# match features between the two images
M = self.matchKeypoints(kpsA, kpsB, featuresA, featuresB, ratio, reprojThresh)

# if the match is None, then there aren't enough matched
# keypoints to create a panorama
if M is None:
    return None

# together
(matches, H, status) = M
result = cv2.warpPerspective(imageA, H, (imageA.shape[1] + imageB.shape[1], imageA.shape[0]))
result[0:imageB.shape[0], 0:imageB.shape[1]] = imageB

# check to see if the keypoint matches should be visualized
if showMatches:
    vis = self.drawMatches(imageA, imageB, kpsA, kpsB, matches, status)

    # return a tuple of the stitched image and the
    # visualization
    return (result, vis)

# return the stitched image
return result

我不明白为什么。我是Python的新手，所以也许这个错误确实很简单，但是我不知道该怎么做。提前谢谢！
