python pyautogui实现图片识别点击失败后重试功能
作者:U盘失踪了
这篇文章主要介绍了python pyautogui实现图片识别点击失败后重试效果,本文通过实例代码给大家介绍的非常详细,感兴趣的朋友跟随小编一起看看吧
安装库
pip install Pillow pip install opencv-python
confidence作用
confidence 参数是用于指定图像匹配的信度(或置信度)的,它表示图像匹配的准确程度。这个参数的值在 0 到 1 之间,数值越高表示匹配的要求越严格。
具体来说,confidence 参数用于调整在屏幕上搜索目标图像时的匹配精度:
0.0 表示完全不匹配。
1.0 表示完全匹配。
在实际应用中,图像匹配的信度可以帮助你处理一些图像上的细微差异。例如,屏幕上的图像可能因为分辨率、光线、颜色等原因与原始图像有些不同。通过调整 confidence 参数,你可以设置一个合理的阈值,使得图像匹配过程既不太严格(导致找不到图像),也不太宽松(导致误匹配)。
举个例子,如果你设置 confidence=0.8,那么只有当屏幕上的图像与目标图像的相似度达到 80% 以上时,才会被认为是匹配的。
识别图片点击
import pyautogui import time import os def locate_and_click_image(image_path, retry_interval=2, max_retries=5, click_count=1, confidence=None): """ 定位图片并点击指定次数。 :param image_path: 图片路径 :param retry_interval: 重试间隔时间(秒) :param max_retries: 最大重试次数 :param click_count: 点击次数 :param confidence: 图像匹配的信度(0到1之间),需要安装 OpenCV :return: 图片的位置 (x, y, width, height) 或 None(如果未找到) """ if not os.path.isfile(image_path): print(f"错误:图片路径无效或文件不存在: {image_path}") return None retries = 0 while retries < max_retries: try: if confidence is not None: location = pyautogui.locateOnScreen(image_path, confidence=confidence) else: location = pyautogui.locateOnScreen(image_path) if location is not None: print(f"找到图片: {image_path},位置: {location}") center = pyautogui.center(location) for _ in range(click_count): pyautogui.click(center) print(f"点击图片中心位置。点击次数:{_ + 1}") return location else: print(f"未找到图片: {image_path},{retry_interval}秒后重试...(重试次数: {retries + 1}/{max_retries})") time.sleep(retry_interval) retries += 1 except pyautogui.ImageNotFoundException: print(f"未找到图片: {image_path},{retry_interval}秒后重试...(重试次数: {retries + 1}/{max_retries})") time.sleep(retry_interval) retries += 1 print(f"达到最大重试次数: {max_retries},未找到图片: {image_path}") return None def main(): image_path = '1.png' # 替换为你的图片路径 retry_interval = 2 max_retries = 5 click_count = 1 confidence = 0.8 # 如果不使用 OpenCV,请将此参数设置为 None location = locate_and_click_image(image_path, retry_interval, max_retries, click_count, confidence) if location: print("操作完成。") else: print("未能定位到图片,程序结束。") if __name__ == "__main__": locate_and_click_image('1.png', retry_interval=2, max_retries=5, click_count=2, confidence=0.8)
优化代码,识别多张图片并点击
import pyautogui import time import os def locate_and_click_image(path, retry_interval=2, max_retries=5, click_count=1, confidence=None): if not os.path.isfile(path): print(f"错误:图片路径无效或文件不存在: {path}") return None retries = 0 while retries < max_retries: try: if confidence is not None: location = pyautogui.locateOnScreen(path, confidence=confidence) else: location = pyautogui.locateOnScreen(path) if location is not None: print(f"找到图片: {path},位置: {location}") center = pyautogui.center(location) for _ in range(click_count): pyautogui.click(center) print(f"点击图片中心位置。点击次数:{_ + 1}") return location else: print(f"未找到图片: {path},{retry_interval}秒后重试...(重试次数: {retries + 1}/{max_retries})") time.sleep(retry_interval) retries += 1 except pyautogui.ImageNotFoundException: print(f"未找到图片: {path},{retry_interval}秒后重试...(重试次数: {retries + 1}/{max_retries})") time.sleep(retry_interval) retries += 1 print(f"达到最大重试次数: {max_retries},未找到图片: {path}") return None def main(): images = [ {'path': '1.png', 'retry_interval': 2, 'max_retries': 5, 'click_count': 1, 'confidence': 0.8}, {'path': '3.png', 'retry_interval': 2, 'max_retries': 5, 'click_count': 1, 'confidence': 0.8}, # 添加更多图片 ] for image in images: location = locate_and_click_image(**image) if location: print(f"图片 {image['path']} 操作完成。") else: print(f"未能定位到图片 {image['path']},程序结束。") if __name__ == "__main__": main()
优化代码,识别多张图片,只要识别到图片就结束循环
import pyautogui import time import os def locate_and_click_image(path, retry_interval=2, max_retries=5, click_count=1, confidence=None): if not os.path.isfile(path): print(f"错误:图片路径无效或文件不存在: {path}") return None retries = 0 while retries < max_retries: try: if confidence is not None: location = pyautogui.locateOnScreen(path, confidence=confidence) else: location = pyautogui.locateOnScreen(path) if location is not None: print(f"找到图片: {path},位置: {location}") center = pyautogui.center(location) for _ in range(click_count): pyautogui.click(center) print(f"点击图片中心位置。点击次数:{_ + 1}") return True else: print(f"未找到图片: {path},{retry_interval}秒后重试...(重试次数: {retries + 1}/{max_retries})") time.sleep(retry_interval) retries += 1 except pyautogui.ImageNotFoundException: print(f"未找到图片: {path},{retry_interval}秒后重试...(重试次数: {retries + 1}/{max_retries})") time.sleep(retry_interval) retries += 1 print(f"达到最大重试次数: {max_retries},未找到图片: {path}") return False def main(): images = [ {'path': '1.png', 'retry_interval': 2, 'max_retries': 5, 'click_count': 1, 'confidence': 0.8}, {'path': '3.png', 'retry_interval': 2, 'max_retries': 5, 'click_count': 1, 'confidence': 0.8}, {'path': '4.png', 'retry_interval': 2, 'max_retries': 5, 'click_count': 1, 'confidence': 0.8}, # 添加更多图片 ] for image in images: success = locate_and_click_image(**image) if success: print(f"图片 {image['path']} 操作完成。") break else: print(f"未能定位到图片 {image['path']}。") if __name__ == "__main__": main()
