要让不同亮度的多张图片变成相同亮度，可以使用Python中的PIL库来实现。具体步骤如下： 1. 导入PIL库 ``` python from PIL import Image ``` 2. 加载图片 ``` python img1 = Image.open("img1.jpg") img2 = Image.open("img2.jpg") ``` 3. 将图片转换为RGB模式 ``` python img1 = img1.convert("RGB") img2 = img2.convert("RGB") ``` 4. 获取图片的亮度值 ``` python def get_brightness(image): # 转换为灰度图 gray_image = image.convert('L') # 计算灰度图的平均像素值 pixels = gray_image.getdata() avg_brightness = sum(pixels) / len(pixels) return avg_brightness brightness1 = get_brightness(img1) brightness2 = get_brightness(img2) ``` 5. 计算亮度差值 ``` python brightness_diff = brightness2 - brightness1 ``` 6. 调整亮度 ``` python def adjust_brightness(image, brightness_diff): # 获取每个像素点的颜色值 pixels = image.load() # 调整像素点的颜色值 for i in range(image.size[0]): for j in range(image.size[1]): r, g, b = pixels[i, j] r += brightness_diff g += brightness_diff b += brightness_diff pixels[i, j] = (r, g, b) return image if brightness_diff > 0: img1 = adjust_brightness(img1, brightness_diff) else: img2 = adjust_brightness(img2, -brightness_diff) ``` 7. 保存图片 ``` python img1.save("img1_adjusted.jpg") img2.save("img2_adjusted.jpg") ``` 这样就可以将多张亮度不同的图片调整为相同亮度，并保存调整后的图片。
