If customization is needed to accommodate a specific camera, you can extend StCameraInterface class and either create a new ROS node or modify the existing stcamera_node (StCameraNode class) to support the specific camera. One is the /camera/image_raw and /camera/camera_info. The ros/time.h header represents the ROS clock time. Implementing ORB-SLAM on Ubuntu 18.04 & ROS Melodic. This is an important step because, when your orb_slam2_ros node runs, it will publish the live image from the camera that contains the currently found key points along with a status text. Link to other relavant post. This will be published on the /debug_image topic. I may be missing an easy fix, but it looks like the node from ubiquity robotics only works for kinetic?
