使用 PIL 或 cv2 等模块在 python 中捕获屏幕的最有效方法是什么?因为它占用大量内存。
我想教 AI 通过屏幕抓取和整洁的方式来玩 Chrome 的恐龙游戏,但它的速度很慢......
我努力了:
import numpy as np
from PIL import ImageGrab
import cv2
import time
last_time = time.time()
while True:
printscreen_pil = ImageGrab.grab(bbox= (0, 40, 800, 640))
printscreen_numpy = np.array(printscreen_pil.getdata(), dtype = 'uint8').reshape((printscreen_pil.size[1], printscreen_pil.size[0], 3))
print(f'the loop took {time.time() - last_time} seconds')
last_time = time.time()
cv2.imshow('window', printscreen_numpy)
if cv2.waitKey(25) & 0xFF == ord('q'):
cv2.destroyAllWindows()
break
>
# average time = the loop took 2.068769931793213 seconds
