python - 如何使用 sikuli 比较两个图像的内容？

Question

import shutil
import os
wait(5)
dir = os.path.dirname(getBundlePath()) # the folder, where your script is stored
img = capture(SCREEN) # snapshots the screen
shutil.move(img, os.path.join(dir, "shot.png")) # to make it persistent
wait(10)
dir = os.path.dirname(getBundlePath()) # the folder, where your script is stored
img2 = capture(SCREEN) # snapshots the screen
shutil.move(img2, os.path.join(dir, "shot2.png")) # to make it persistent
if img == img2:
    popup("hello")
else:
    popup("hi")

它总是弹出 hi not hello ...虽然我没有改变屏幕。

我可以理解这两个是两个不同的图像名称，这就是为什么 else 块总是工作的原因。但是是否可以比较这两个图像。两张图片的内容，两者之间存在一些差异。无法上传代码，因此已对其进行了评论。如果有人知道，请提供帮助。

Ideally Sikuli works if you already have an image that your comparing against what's found on the screen. Below I dynamically create a region, then snap a picture, and finally compare the saved picture against what in the dynamically created region.

imagePath1 = capture()  #snapshots the screen
image1 = exists(imagePath1)  #Create a Match object
imagePath2 = capture()  #snapshots the screen
image2 = Pattern(imagePath2)  #Create a Matach Object
myRegion = Region(image1)  #make new region from the match object
if myRegion.exists(image2): #look in the region
    print "hello" #yeah it's in the region of the screen
else:
    print "hi"  #nope not there....

This one is more like what you want i beleive. You can take three different pictures and then a smaller picture of the one yout want. If you call getScore() it will return precent match http://doc.sikuli.org/match.html#Match

imagePath1 = capture('Match obj take large picture') # snapshots the screen
matchObj1 = exists(imagePath1) #Make match object

imagePath2 = capture('Match obj take large picture') # snapshots the screen
matchObj2 = exists(imagePath2) #Make match object

imagePath3 = capture('Match obj take large picture') # snapshots the screen
matchObj3 = exists(imagePath3) #Make match object

imagePath4 = capture('Target, take small picture') # snapshots the screen 
patternIwant = Pattern(imagePath4) #Make a pattern object search against

matchList = [matchObj1, matchObj2, matchObj3]

for m in matchList:
    arg = m.exists(patternIwant)
    if arg != None:
        print 'image score  ', arg.getScore()
    else:
        print 'no match'
    if m.exists(patternIwant):
        print "hello"
    else:
        print "hi"
