Feature-Based Robotic Mapping with Generalized Labeled Multi-Bernoulli Filters for Planetary Landers
The feature-based robotic mapping (FBRM) problem is concerned with building, maintaining, and refining a feature map, such as terrain, pieces of furniture in a room, or obstacles in a parking lot, about a mobile sensor whose trajectory is assumed known. The nature of the problem necessitates that an FBRM method account for a possibly varying number of map elements, spurious measurements from the sensor, and missed detections. Filtering methods that employ random finite sets are generating substantial interest among the research community, and recently, approaches that append labels to the individual set elements have shown impressive theoretical support and performance. This work aims to illustrate the use of one of these tools, the generalized labeled multi-Bernoulli filter, for FBRM and compare it to some alternative random finite set-based filters. The method is demonstrated in a simulation where a lunar lander traverses an uncertain terrain as a camera on-board the vehicle takes measurements of the feature locations as pixel-coordinates in the camera's image plane. These observations are used to feed the corrector stage of the filter to perform FBRM as the vehicle descends along its trajectory.
