Residence status analyzer , residence situation analysis system and residence situation analysis methods

摘要

A staying state analysis device measuring a stay frequency of moving objects in a target area and generating a heat map visualizing a state of distribution of the stay frequency includes: a position information sorter soring pieces of position information of the moving objects according to a degree of possibility that the pieces of position information may include an error due to a missing part that may be in traffic lines of the moving objects; a missing part position detector detecting a position of the missing part in the traffic lines based on at least two groups of pieces of position information sorted by the sorter; a corrected distribution information generator generating corrected distribution information representing the stay frequency of the moving objects corrected based on a result of detection by the missing part position detector; and a heat map generator generating the heat map based on corrected distribution information.
