how to make locateCenterOnScreen more accurate -PYTHON-, -WINDOWS-
To make the locateCenterOnScreen
function in Python's pyautogui
library more accurate on Windows, you can try the following techniques:
Increase the
confidence
parameter: ThelocateCenterOnScreen
function accepts aconfidence
parameter that determines the threshold for matching the image on the screen. By increasing theconfidence
value, you can make the function more strict and accurate. The default value is 0.8, but you can experiment with higher values to find the optimal threshold for your specific use case.Example:
pythonimport pyautogui
# Increase confidence value
x, y = pyautogui.locateCenterOnScreen('image.png', confidence=0.9)
Use a higher-resolution image: Provide a higher-resolution image of the target element for
locateCenterOnScreen
. A higher-resolution image can help improve accuracy, especially when dealing with small or intricate details. Ensure that the image you use matches the actual appearance of the element as closely as possible.Adjust screen resolution and scaling: Sometimes, discrepancies between the screen resolution and scaling settings can affect the accuracy of image matching. Ensure that your screen resolution is set to the native resolution and check the scaling settings in the Windows display settings. Adjusting these settings to match the expected resolution and scaling can help improve accuracy.
Refine the image: If the image you're using for matching contains unnecessary details or noise, consider refining it by cropping or resizing to focus on the essential elements. Removing irrelevant parts from the image can help improve the accuracy of the matching process.
Use region-specific matching: If you know the approximate region where the target element is located, you can narrow down the search area by specifying a region parameter in the
locateCenterOnScreen
function. This can help reduce the search space and improve the speed and accuracy of matching.Example:
pythonimport pyautogui
# Specify a region to search
region = (100, 100, 300, 300) # (left, top, width, height)
x, y = pyautogui.locateCenterOnScreen('image.png', region=region)
By combining these techniques, you can enhance the accuracy of the locateCenterOnScreen
function in pyautogui
on Windows. It may require some experimentation and adjustment to find the optimal settings for your specific use case.
