QUESTION
I am making a program that detects lasers and circles and numbers then with the opencv library. This is my first time using ros indigo and I don't really know what I am doing but I am getting an error that is repeating at a rapid rate when I run my program. this is the error I am getting:
[ERROR] [WallTime: 1565273888.861720] bad callback: Traceback (most recent call last): File "/opt/ros/indigo/lib/python2.7/dist-packages/rospy/topics.py", line 720, in _invoke_callback cb(msg) File "lazer3.py", line 89, in callback cv_image2 = self.convert_image(cv_image) NameError: global name 'self' is not defined
the error is in the line that says cv_image2 = self.convert_image(cv_image) and it is because I use the self if I delete self I get a different error:
[ERROR] [WallTime: 1565274017.459066] bad callback: Traceback (most recent call last): File "/opt/ros/indigo/lib/python2.7/dist-packages/rospy/topics.py", line 720, in _invoke_callback cb(msg) File "lazer3.py", line 89, in callback cv_image2 = convert_image(cv_image) File "lazer3.py", line 29, in convert_image labels = measure.label(thresh, neighbors=8, background=0) AttributeError: 'module' object has no attribute 'label'

Answered 2018-Dec-27 at 05:34From screen-shot, it is clear that u are giving input in the form of file whereas in the code the image is accepted as a encoded base64 form.
Give the input as encoded base64 form of the image. This encoding can be done online using any encoding website. https://www.base64-image.de/
QUESTION
I am new to ROS. I am playing with integrating OpenCV and ROS. The code I am using is inspired from the ROS tutorial on converting ROS messages to CV::mat and back.
I am subscribing to the topic /raspicam_node/image/compressed published by the raspicam node. I have no problem getting the topic, converting it to CV:mat, and modifying it with OpenCV. Line 32 opens a window and shows me the modified CV:mat image.
My issue comes at Line 36. I can see the topic using rostopic list but when I echo it nothing comes up. Same if I use rqt_image_view.
Any thoughts on what I am missing? Thank you!
...ANSWER
Answered 2018-Aug-11 at 10:29If you check rostopic echo /modified_image you can see that your topic is successfully published.
rqt_image_view will display it if you call your published topic modified_image/compressed.
From the compressed_image_transport wiki:
publish it on a topic of the form image_raw/compressed. Then any ROS node using image_transport can subscribe to image_raw with transport compressed, just as if image_transport were used on the publisher side
