OpenCV Canny邊緣輪廓檢測，Python

假設一張這樣的圖片：

檢測邊緣輪廓：

# OpenCV Canny邊緣輪廓檢測，Python
import cv2

if __name__ == "__main__":
    img = cv2.imread("pic.jpg")
    # 高斯模糊
    gaussian_img = cv2.GaussianBlur(img, (3, 3), 0)

    result = cv2.Canny(gaussian_img, 200, 480)
    cv2.imwrite("canny.jpg", result)

    cv2.imshow("canny", result)
    cv2.waitKey(0)
    cv2.destroyAllWindows()

 

結果：
