Breadboard Model of a 3d Lidar Sensor for Real-time Pose Estimation of Spacecraft
Reliable relative navigation between two spacecraft is a critical element of future On Orbit Servicing (OOS) missions and space debris removal scenarios. Sensors are required that allow for accurate estimates of a target satellite’s relative position and attitude. Scanning LiDAR (Light RADAR, also Light Detection And Ranging) based sensors are capable of creating a three dimensional point cloud...
متن کاملConditional Random Fields for Airborne Lidar Point Cloud Classification in Urban Area
Over the past decades, urban growth has been known as a worldwide phenomenon that includes widening process and expanding pattern. While the cities are changing rapidly, their quantitative analysis as well as decision making in urban planning can benefit from two-dimensional (2D) and three-dimensional (3D) digital models. The recent developments in imaging and non-imaging sensor technologies, s...
متن کاملTriDAR Test Results Onboard Final Shuttle Mission, Applications for Future of Non-Cooperative Autonomous Rendezvous & Docking
This paper presents results from the final Space Shuttle test flight of the TriDAR vision system onboard Shuttle Atlantis on STS-135. The TriDAR (Triangulation + LIDAR) is a proximity operations 3D vision system for Autonomous Rendezvous and Docking (AR&D) missions to non-cooperative targets in space. The TriDAR has previously flown on STS-128 and STS-131 onboard Shuttle Discovery. The objectiv...
متن کاملTriDAR: A HYBRID SENSOR FOR EXPLOITING THE COMPLEMENTARY NATURE OF TRIANGULATION AND LIDAR TECHNOLOGIES
3D ranging technologies generally fall into either position-based (triangulation) or time-based (LIDAR) approaches. Triangulation can provide much higher precision at close to mid-range but degrades quickly with the square of distance. LIDARs can provide reasonable precision over much longer distances but, unlike triangulation, they do not improve in capabilities at short range where precision ...
متن کاملRobust Tumbling Target Reconstruction through Fusion of Vision and LIDAR for Autonomous Rendezvous and Docking On-Orbit
This milestones report details progress toward 3D target reconstruction through fusion of vision and LIDAR data. The utility of using both vision and LIDAR for on-orbit target reconstruction is first presented. The technical approach, including a new camera-LIDAR Structure from Motion (SfM) framework, is next presented, though this technical framework is provisional at present. Validation metho...
