如何在Visual-Studio-Code中链接外部库(opencv)以调试python ros-package

#!/usr/bin/env python

import cv2
import rospy
from sensor_msgs.msg import Image
from cv_bridge import CvBridge

class ImageProcessor:
    def __init__(self):
        self.bridge = CvBridge()
        self.image_sub = rospy.Subscriber("/camera/image_raw", Image, self.image_callback)

    def image_callback(self, data):
        try:
            cv_image = self.bridge.imgmsg_to_cv2(data, "bgr8")
        except Exception as e:
            rospy.logerr(e)
            return

        # 处理图像
        gray_image = cv2.cvtColor(cv_image, cv2.COLOR_BGR2GRAY)
        cv2.imshow("Image", gray_image)
        cv2.waitKey(3)

def main():
    rospy.init_node('image_processor', anonymous=True)
    image_processor = ImageProcessor()
    try:
        rospy.spin()
    except KeyboardInterrupt:
        print("Shutting down")
    cv2.destroyAllWindows()

if __name__ == '__main__':
    main()
