Read rostopic /detection_image

[lsy311]

Hi, I got this yolov4-for-darknet_ros works, can output a window with objects are detected.
But when I check the rostopics be published and try to use the rqt_image_view to load and show the rostopic /darknet_ros/detection_image , I got the problem with the topic can not be shown like this:

Do anyone have the same problem? How this can be solved?

Hi lsy311

Thank you for use yolov4-for-darknet_ros!
I had a similar problem, but I was able to solve it.
I solved this problem by changing enable_opencv: true to enable_opencv: false in darknet_ros/darknet_ros/config/ros.yaml.

image_view:

  enable_opencv: false
  wait_key_delay: 1
  enable_console_output: true

However, the cause of the problem is not well understood.:disappointed_relieved:
