Correlative scan matching csm
Web2.To maximize the overall performance, we implement the scan matching part on the FPGA fabric. Specifically, we develop an accelerator for Correlative Scan Matching (CSM) proposed by Olson et al. [25], termed CSM core, since it strikes a balance between computational efficiency and robustness. We also modify the CSM Webaccelerator for Correlative Scan Matching (CSM) proposed by Olson et al. [15], since it strikes a balance between computa-tional efficiency and simplicity. To parallelize the algorithm and further improve the efficiency, we modify the original CSM algorithm and also perform design optimizations, such as
