Flow line analysis system and flow line analysis method

摘要

A camera device transmits a captured image and flow line information of moving objects to a server device for each predetermined transmission period. The server device generates a flow line analysis image in which the flow line information of the moving objects is superimposed on the captured image and displays the generated flow line analysis image on a display. The server device displays a first flow line analysis image generated based on a captured image and flow line information in a first period which is arbitrary designated, and receives an instruction by a user operation to shift the first period by an amount. The server device sets a second period by shifting the first period by the amount without changing a length in period, and displays a second flow line analysis image generated based on a captured image and flow line information in the second period.
