cv2.createStitcher() not enough keypoints?

Good day,

I am working on a project to have multiple cameras, each taking an image and then the images will be stitched together. Currently I am trying to use the cv2.createStitcher().stitch(images) function. Below is the code that I use:

import cv2

imageFiles = ['imageCapture1_0.png','imageCapture2_0.png']
images =
for filename in imageFiles:
img = cv2.imread(filename)
images.append(img)

cv2.ocl.setUseOpenCL(False)
stitcher = cv2.createStitcher()
status, result = stitcher.stitch(images)

cv2.imwrite('result.png',result)


The image input is:

left image:

right image:

However, result output type becomes NoneType with size 1 and value: NoneType object of builtins modules. From what I have googled, the cause of this is because there is not enough matching keypoint to stitch the images together. If so, is there a way to stitch image even with less keypoint? Is there a way to set the parameter? I read through the documentation with no luck trying to find the solution. Thank you in advance
