MU Lili, CHEN Kai, HE Shizheng, et al. Genetic algorithms for sanning matching of 2D laser data fused with NDT[J]. 2021, (3): 123-126. DOI: 10.13873/J.1000-9787(2021)03-0123-04.
Aiming at the problem that in Laser data scanning matching
Normal distribution transform( NDT)algorithm is easy to fall into local extremum when the initial error is large
a genetic algorithm fused with NDT is proposed. NDT is introduced to construct the grid
and a lookup table is established to speed up the solution speed. The genetic algorithm is used to search the optimal matching between the current laser frame scanning data and the reference laser frame scanning data. The simulation results show that the algorithm achieves good effect in laser data scanning matching
and further improves the positioning precision of mobile robots.
