Abstract: The analysis of indoor mobile object trajectory data is an application foundation with important commercial value such as retail promotion, indoor space planning, and advertising bidding. It is also an indispensable part in public safety and emergency solutions. In recent years, it has received more and more attention from researchers. In order to realize the cluster analysis of indoor moving object trajectory, this paper proposes a comprehensive analysis method combining DBSCAN clustering algorithm with visualization.This paper uses DBSCAN algorithm to cluster the indoor trajectory data based on mobile phone wifi information collected in a shopping mall building, analyzes the obtained clustering results and information, and provides certain reference information for the layout planning and store adjustment of the mall.Finally, the indoor trajectory data of the mall building is visualized and displayed, and the display effect is compared with the clustering result to verify each other.

Key words: cluster analysis, DBSCAN algorithm, heat map, visualization
