locateAllOnScreen finds the same image more than once

Question

So I have this Image ,this Template image and this code:

Image:

Template:

code:

list(pyautogui.locateAllOnScreen(r'C:\Desktop\chromatic.png', grayscale = True, confidence = 0.9))

The picture is in grayscale for faster times but even if I put the original it doesn't work.

So the problem is that it finds 6-7 occurrences instead of 4, so the template matches the same image more than once. I tried switching confidence etc but nothing works. What can I do?

Answer 1

I've faced with the same problem. The problem is that locateAllOnScreen finds the same image several times shifted by 1-2 pixels. I solved the problem by filtering the found images (distance between images should be more than 10 px: (x1-x2)² + (y1-y2)² > distance²).

def locate_all(path, confidence=0.9, distance=10):
    distance = pow(distance, 2)
    elements = []
    for element in pyautogui.locateAllOnScreen(path, confidence=confidence):
        if all(map(lambda x: pow(element.left - x.left, 2) + pow(element.top - x.top, 2) > distance, elements)):
            elements.append(element)
    return elements
