RESTORATION OF FRAGMENTARY TRAJECTORIES USING EVALUATION OF IDENTITY AND COMBINATORIAL OPTIMIZATION

摘要

In this research, we propose the method which detects the optimum matching of the fragmentary trajectories using the method of evaluating identities of pedestrians and the method of combinatorial optimization. Our proposed method helps us understand the flows of pedestrians at certain space by restoring the fragmentary trajectories of the same pedestrians. In addition, we verify the accuracy of proposed method by applying it to the fragmentary trajectories tracked at the concourse of the railway station in Tokyo at the rush hour using laser range scanners.
