An optimized NLO-CSM algorithm is adopted in this work to reduce the computation resources and the amount of computation, as well as avoid the high computational complexity of brute force searching on the grid map in the conventional CSM algorithm, while maintaining a good scan match performance. By using 200 different poses as the initial value of the fine match process to calculate the corresponding H and K matrices, this study uses the normalized root mean square error (NRMSE) to evaluate errors of the NLO-CSM hardware accelerator against the CPU software results. = fastslam, Maintainer status: maintained; Maintainer: Michel Hidalgo
