Marginalization slam

Webmarginalization has the disadvantage of causing loss of spar-sity, increasing computational cost, and does not allow for relinearization, damping the accuracy. In the graph-SLAM context, sparsification is the process of finding the best sparse and relinearizable approximation to the result of marginalization. The impact of sparsification WebDec 31, 2013 · This work is motivated by robot-sensor network cooperation techniques where sensor nodes (beacons) are used as landmarks for range-only (RO) simultaneous localization and mapping (SLAM). This paper presents a RO-SLAM scheme that actuates over the measurement gathering process using mechanisms that dynamically modify the …

WebI have read in SLAM papers talk about marginaliztion. I am confused about how this process works, why you do it and how it differs from global smoothing. In particular if you're interested in Windowed Smoothing I don't understand how marginaliztion is different than full bundle adjustment?
