Towards Lazy Data Association in SLAM

In Proc. of the International Symposium on Robotics Research (ISRR), 2003.







Abstract:

We present a lazy data association algorithm for the simultaneous localization and mapping (SLAM) problem. Our approach uses a treestructured Bayesian representation of map posteriors that makes it possible to revise data association decisions arbitrarily far into the past. We describe a criterion for detecting and repairing poor data association decisions. This technique makes it possible to acquire maps of largescale environments with many loops, with a minimum of computational overhead for the management of multiple data association hypotheses. A empirical comparison with the popular FastSLAM algorithm shows the advantage of lazy over proactive data association.
