A robust and fast algorithm to solve the lost in space problem for star trackers is presented in this paper. The algorithm is based on an image processing technique, the Shortest Distance Transform, which transforms the camera image into a 2D look-up table. The information from the database can then be efficiently passed into this table to compare the(More)
In this paper, a star tracker attitude estimation procedure with increased robustness and efficiency, using the AIM (Attitude Estimation using optimal Image Matching) algorithm, is presented and validated. The unique approach of the AIM algorithm allows us to introduce a reliable quality check which can be efficiently calculated. Unlike existing validation(More)
This paper presents the experimental validation of an approach based on a coordinate-free representation to recognize six DOF rigid body motion trajectories. In this approach, the three dimensional measured position trajectories of arbitrary and uncalibrated points attached to the rigid body are transformed to an invariant, coordinatefree representation of(More)
