STAYING STATE ANALYSIS DEVICE, STAYING STATE ANALYSIS SYSTEM AND STAYING STATE ANALYSIS METHOD

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 sorting 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.

1. A staying state analysis device for 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 for display on a display device, the staying state analysis device comprising:
a processor; and a memory storing instructions, wherein the processor, when performing the instructions stored in the memory, comprises: a position information sorter that sorts pieces of position information of the moving objects obtained from a moving object detection device in accordance with a degree of possibility that the pieces of position information may include an error due to a missing part that may be created in traffic lines of the moving objects; a missing part position detector that detects a position of the missing part in the traffic lines based on at least two groups of pieces of position information sorted by the position information sorter; a corrected distribution information generator that generates 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 that generates the heat map based on the corrected distribution information generated by the corrected distribution information generator.
