Pyautogui图像识别

Question

我试图让这段代码在屏幕上找到图像（1920x1080），但什么都不做，直到它看不到图像，然后运行一个基本的打印，说“无图像”

代码：

import time
import keyboard
import pyautogui
import win32api
import win32con
import schedule


def click():
    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTDOWN, 0, 0)
    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTUP, 0, 0)
    time.sleep(0.1)


while not keyboard.is_pressed('q'):
    start = pyautogui.locateCenterOnScreen('7.png', region=(0, 0, 1920, 1080), grayscale=True, confidence=0.70)
    if start is not None:
        pyautogui.moveTo(start)  # Moves the mouse to the coordinates of the image
        click()
    else:
        print("No image")

schedule.every(1).seconds.do(click)

while True:
    schedule.run_pending()
    time.sleep(1)

没关系，我找到了解决方案..

try:
    location = pyautogui.locateOnScreen('7.png')
    print('image found')
except pyautogui.ImageNotFoundException:
    print('ImageNotFoundException: image not found')
