    摘要: The present invention pertains in general to a single, integrated flash LADAR system and method. The system includes data processing hardware and software, a passive two-dimensional camera, a three-dimensional camera, a light source, and a common optical path. One or more star trackers can also be included. In addition, auxiliary components, such as an inertial measurement unit and a global positioning system receiver can be included. The system can be closely integrated with a critical algorithm suite that operates in multiple modes, in real-time to enable landing, docking, and navigation functions, such as Guidance, Navigation, and Control (GNC), Altimetry, Velocimetry, Terrain Relative Navigation (TRN), Hazard Detection and Avoidance (HDA), and dust penetration.

    摘要: The present invention pertains to the identification of a set of measurement data, using an a priori model database, which is then used in the determination of a pose solution using LADAR data. In particular, a model database of a target scene is created. The model database includes location information for a plurality of points within the target scene, and separation distances between sets of those points defining triangles. LADAR data obtained from a target scene is processed to extract features. Location information and separation distances between sets of extracted features defining triangles are placed in a measurement database. Separation distances contained in the measurement database are compared to separation distances contained in the model database. If a match is found, a rotation quaternion and translation vector are calculated, to transform the data in the measurement database into the frame of reference of the data in the model database. The rotation quaternion and translation vector can be applied to additional sets of data defining additional triangles, to verify that the target scene has been correctly identified. A pose solution and range can then be output.
