使用PyAutoGUI在屏幕上定位图像，无论色调/亮度如何

Question

I'm looking for a simple way in Python (PyAutoGUI) to locate all the images of a certain type on the screen but here's the catch, each image has a different gradient / color tone and I don't want to take the screen shot of each and every image to locate them on screen.

Here's the region of the screen containing the images I am trying to get the coordinates of:

As you can see every square has a unique color (the contrast).

So I want to get the coordinate of every square making PyAutoGUI scan just one image. Is there any way I could make it ignore the difference in contrast of the images? Like making it black and white mode or something.

How the code works:

import pyautogui
coordinates = pyautogui.locateAllOnScreen("image.png") # Returns list of coordinates of all images matching image.png

Answer 1

I would try the following:

pyautogui.locateOnScreen("image.png", grayscale=True)

Which will ignore color values and simply compaire the contrast of values. This has the added benefit of comparing about 30% quicker but can lead to false positives.

Answer 2

I know this is 2 years old but for any future humans that find this like me try the confidence argument.

import pyautogui
button7location = pyautogui.locateOnScreen('calc7key.png', confidence=0.9)
button7location
Box(left=1416, top=562, width=50, height=41)
