Hi,

I am having an issue where by I am unable to connect to the AR Drone camera when the drone is connected through ROS using the ardrone_autonomy ardrone.launch.

I think the issue is due to the fact that I am trying to access the drone camera through the ip address with OpenCV and Python while connected through ardrone_autonomy. Below is a code snippet of how I am accomplishing this.

{

video_capture = cv2.VideoCapture()

video_capture.open('tcp://192.168.1.1:5555')

vidWidth = video_capture.get(cv2.CAP_PROP_FRAME_WIDTH)

vidHeight = video_capture.get(cv2.CAP_PROP_FRAME_HEIGHT)

}

As you can see that I am using the IP address for the camera. This works perfectly when the drone is not connected through ros which is essentially like a webcam. My end goal is for tracking and navigation through the use of images received from the camera using OpenCV which means I will have to issue movement commands(cmd_vel) which requires a connection through ardrone_autonomy based on the images received and processed by OpenCV.

Is there anyway I can accomplish this by using the IP camera from the drone while connected to ROS?

Thanks for any help!
