Starting mono node from topic /camera/image_raw?
I am using the package ORB_SLAM2. I have problems starting the Mono node from the topic. when I do
rosrun ORB_SLAM2 Mono <path_to_vocabulary_file> <path_to_yaml_file>
it starts and loads the vocabulary but then the frame window remains empty and displays waiting for the images. So whats the method to start Monocular node from topic /camera/image_raw? Original link
