In this work, the stereo camera D435 and the solid-state LIDAR HPS-3D160, together with the previously present ZED camera, have been integrated into the RACOON-Lab laboratory at TUM. The resulting hardware structure enables a swift appending of future new sensors to the platform, while the new storage format enables storing all the results in an open and extensible format for current and future usage. The software framework also requires minimum changes for a new addition to the system, while also enabling the development of new algorithms and filters without the need of a full rewrite.
The completed setup has then been tested under orbital light conditions, where the laboratory simulated a short-range fly-around of a target satellite under the illumination of an Earth's albedo simulation and without the presence of external lights while changing the inclination of the target between the various measurements procedures. As external illumination factors do not influence the LIDAR, its HDR integration time has been changed between the two situations.
The resulting depth information recorded, as it was or after being filtered of the background, has been feed to the path tracking DIFODO algorithm, where the paths have been extracted. The resulting trajectories have been examined by applying a previously developed metric, and the computed parameters have been analyzed.
The resulting data show few dependencies from the position of the target and the quality of the metric parameters. For the selected settings of the tracking algorithm and the filter, elevated drift values have been found for the D435 and the HPS-3D160, while the ZED presents, overall, better results.
