在这个示例中,我们定义了一个名为process_image的函数,并尝试将一个不是NumPy数组的image_list对象传递给它。运行这段代码将会导致我们遇到上述的错误提示:“Overload resolution failed: - img is not a numpy array, neither a scalar”。 解决方法 要解决这个错误,我们需要确保将正确的参数传递给函数。在这种情...

函数'cv::cvtColor‘中的_src.empty()当我们使用OpenCV库的cv2.resize()函数对图像进行缩放操作时,有时候可能会遇到以下错误:cv2.error: C:\projects\opencv-python\opencv\modules\imgproc\src\resize.cpp:4044: error: (-215) s。这个错误通常是由于函数参数设置不正确引起的。
import cv2 import os image_paths = ['path_to_image1.jpg', 'path_to_image2.jpg', ...] shapes = [] for path in image_paths: img = cv2.imread(path) if img is not None: shapes.append(img.shape) else: print(f"图像 {path} 加载失败。") print(shapes) 通过这种方式,可以检查所有图...
