As part of a Google Summer Of Code (GSOC). I have the privilege to Mentor a talented PhD Student of the Nanyang Technological University of Singapore, named Thien Nguyen.
Since the beginning of this project , Thien has delivered a series of Labs to serve not only as milestones for the project but also a step-by-step guideline for anyone who wishes to learn about using the power of computer vision for autonomous robot to follow. The labs include:
I invite you to read about this series of well detailed experimentations and instructions on how you can implement the RealSense T265 tracking camera system :
Here is a video showing autonomous indoor flight using the system in ROS-Mavros environment (this is part of Lab 4):
Lab 5 shows how to fly using a Python Scrit sending MavLink Message Vision_Position_Estimate directly to Flight Controller.
You can read the underlying principles of how to incorporate a VIO tracking camera with ArduPilot using Python and without ROS. After installing necessary packages, configuring FCU params, the vehicle can integrate the tracking data and perform precise navigation in GPS-less environment. Pose confidence level is also available for viewing directly on GCS to quickly analyse the performance of the tracking camera.
Thanks to Thien for this amazing project, experiments can now be carried on the T265 with different Flight Controllers and stacks compatible with the Vision_Position_Estimate MavLink Message.
