The optimal path algorithm analysis of GPS navigation in taxi management system based on a* algorithm was introduced in this paper. Through improving the traditional Dijkstra algorithm and avoiding problems such as "time-consuming and low efficiency" in Dijkstra algorithm with traversal search for each node, a* algorithm could help the taxi find the optimal path and bring convenience for traffic management.

A detailed study was carried out to find optimal seam-lines for mosaicking of images acquired by an airborne light detection and ranging (LiDAR) *** ground objects labeled as obstacles can be identified by delineating black holes from filtered point clouds obtained by filtering the raw laser scanning *** innovative A algorithm is proposed that can automatically make the seam-lines keep away from these obstacles in the registered *** method can intelligently optimize the selection of seam-lines and improve the quality of orthophotos.A simulated grid image was first used to analyze the effect of different heuristic functions on path *** subsets of LiDAR data from Xi'an,Dunhuang,and Changyang in Northwest China were obtained.A quantitative method including pixel intensity,hue,and texture was *** our proposed method,9.4%,8.7%,and 9.8% improvements were achieved in Dunhuang,Xi'an,and Changyang,respectively.
