Abstract

A camera device generates a captured image, extracts flow line information relating to a staying position or a passing position of a moving object, and transmits the generated captured image and the extracted flow line information of the moving object 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 object is superimposed on the captured image and displays the generated flow line analysis image on a displayer. Furthermore, the server device switches a first flow line analysis image in a first predetermined period to a second flow line analysis image in a second predetermined period according to an operation of changing the period, and displays the resulting flow line analysis image.

Claims

1. A flow line analysis system to which a camera device and a server device are connected,

wherein the camera device

generates a captured image,

extracts flow line information relating to a staying position or a passing position of a moving object, and

transmits the generated captured image and the extracted flow line information of the moving object to the server device for each predetermined transmission period,

wherein the server device

generates a flow line analysis image in which the flow line information of the moving object is superimposed on the captured image,

displays the generated flow line analysis image on a displayer, and

wherein, furthermore, the server device switches a first flow line analysis image generated based on the captured image and the flow line information in a first predetermined period to a second flow line analysis image generated based on the captured image and the flow line information in a second predetermined period according to an operation of changing the period, and displays the resulting flow line analysis image.

3. The system of claim 1,

wherein the camera device repeatedly generates the captured image.

4. The system of claim 1,

wherein the camera device

generates a captured image,

extracts first flow line information relating to a staying position of a moving object and second flow line information relating to a passing position, and

transmits the generated captured image and the extracted flow line information items of the moving object to the server device for each predetermined transmission period, and

wherein, according to a setting, the server device displays a first flow line analysis image in which the first flow line information is superimposed on the captured image or a second flow line analysis image in which the second flow line information is superimposed on the captured image.

5. The system of claim 4,

wherein the server device displays a display setting screen for selecting the first flow line analysis image or the second flow line analysis image on a screen same as the screen on which the first or second flow line analysis image is displayed.

6. The system of claim 1,

wherein the camera device

generates a captured image,

extracts flow line information relating to a staying position or a passing position of the moving object, and

transmits the generated captured image and the extracted flow line information of the moving object to the server device for each predetermined transmission period, and

wherein the server device

displays a time line bar that arbitrarily sets a period of the flow line analysis image in which the flow line information is superimposed on the captured image, and

displays the flow line analysis image in the period arbitrarily set on the time line bar.

7. The system of claim 6,

wherein the server device displays the time line bar on a screen same as the screen on which the flow line analysis image is displayed.

8. The system of claim 6,

wherein the time line bar indicates the presence or absence of the captured image from the camera device and the flow line information for each predetermined period.

2. A flow line analysis system to which a camera device and a server device are connected,

wherein the camera device

generates a background image of a captured image,

extracts flow line information relating to a staying position or a passing position of a moving object, and

transmits the generated background image and the extracted flow line information of the moving object to the server device for each predetermined transmission period,

wherein the server device

generates a flow line analysis image in which the flow line information of the moving object is superimposed on the background image, and

displays the generated flow line analysis image on a displayer, and

wherein, furthermore, the server device switches a first flow line analysis image generated based on the background image and the flow line information in a first predetermined period to a second flow line analysis image generated based on the background image and the flow line information in a second predetermined period according to an operation of changing the period, and displays the resulting flow line analysis image.

9. A flow line analysis method in a flow line analysis system to which a camera device and a server device are connected,

wherein the camera device

generates a captured image,

extracts flow line information relating to a staying position or a passing position of a moving object, and

transmits the generated captured image and the extracted flow line information of the moving object to the server device for each predetermined transmission period, and

wherein the server device

generates a flow line analysis image in which the flow line information of the moving object is superimposed on the captured image,

displays the generated flow line analysis image on a displayer, and

wherein, furthermore, the server device switches a first flow line analysis image generated based on the captured image and the flow line information in a first predetermined period, to a second flow line analysis image generated based on the captured image and the flow line information in a second predetermined period according to an operation of changing the period, and displays the resulting flow line analysis image.
