Moving information analyzing system and moving information analyzing method
A moving information analyzing system includes a camera, and a server that is connected to the camera. The camera captures an image of an object region, extracts moving information regarding a staying position or a passing position of a moving object included in a captured image of the object region, outputs a count line for counting the number of moving objects and a count result of the number of moving objects having passed the count line, related to the moving information, and transmits the captured image and the moving information to the server in a predetermined transmission cycle. The server acquires the captured image and the moving information, generates a moving information analysis image in which the moving information is superimposed on the captured image and to which the count line and the count result are added, and displays the moving information analysis image on a monitor.

a camera; and
a server that is connected to the camera,
wherein the camera, in operation,
captures an image of an object region,
generates a background image of the object region,
generates a count line illustrating a position for which a number of moving objects that pass the count line are counted,
counts the number of moving objects having passed the count line in a predetermined transmission cycle to generate a count result, and
transmits the background image, the count line and the count result of the number of moving objects having passed the count line in the predetermined transmission cycle to the server, and
wherein the server, in operation,
receives the background image, the count line and the count result of the number of moving objects having passed the count line in the predetermined transmission cycle transmitted from the camera,
generates a moving information analysis image in which the count line and the count result of the number of moving objects having passed the count line in the predetermined transmission cycle are added to the background image, and
displays the moving information analysis image on a monitor connected to the server.
2. The system of claim 1 , wherein the camera, in operation, generates the count line in response to an instruction from the server.
3. The system of claim 1 , wherein the camera, in operation, counts a number of bidirectional moving objects on a direction basis as the count result with respect to the count line as a single count line, and wherein the server, in operation, generates the moving information analysis image displaying directions from which the moving objects have passed and the count result on a directional basis.
4. The system of claim 1 , wherein the camera, in operation, generates a plurality of count lines, and counts a respective number of moving objects having passed each of the plurality of count lines as a respective count result, and wherein the server, in operation, generates the moving information analysis image displaying the plurality of count lines having different display aspects as the plurality of count lines and count results respectively corresponding to the plurality of count lines.
5. The system of claim 1 , wherein the camera, in operation, generates a plurality of count lines, and counts multiple numbers of moving objects having passed two or more of the plurality of count lines as the count result, and wherein the server, in operation, generates the moving information analysis image displaying the plurality of count lines having different display aspects as the count lines and multiple count results of the number of moving objects respectively corresponding to combinations of the plurality of count lines.
6. The system of claim 1 , wherein the server, in operation, generates the moving information analysis image displaying arrows having different thicknesses according to the number of moving objects having passed the count line.
7. The system of claim 1 , wherein the camera, in operation, generates a plurality of count line candidates as the count line, and calculates line evaluation values for the plurality of count line candidates, and wherein the server, in operation, generates the moving information analysis image displaying the plurality of count line candidates and recommendation marks indicating an extent of recommendation corresponding to the line evaluation values.
8. The system of claim 1 , wherein the camera, in operation, determines whether a moving object of the moving objects previously crossed a designated line prior to crossing the count line, and if the moving object of the moving objects previously crossed the designated line prior to crossing the count line, includes the crossing of the count line by the moving object in the count result.
9. The system of claim 8 , wherein the camera, in operation, if the moving object of the moving objects did not previously cross the designated line prior to crossing the count line, the camera does not include the crossing of the count line by the moving object in the count result.
10. The system of claim 8 , wherein the count result represents the number of moving objects that crossed a plurality of designated count lines.
11. A moving information analyzing method for a moving information analyzing system in which a camera is connected to a server, the method comprising:
causing the camera to:
capture an image of an object region,
generate a background image of the object region,
generates a count line illustrating a position for which a number of moving objects that pass the count line are counted, and
counts the number of moving objects having passed the count line in a predetermined transmission cycle to generate a count result, and
transmit the background image, the count line and the count result of the number of moving objects having passed the count line in the predetermined transmission cycle to the server; and
causing the server to:
receive the background image, the count line and the count result of the number of moving objects having passed the count line in the predetermined transmission cycle transmitted from the camera,
generate a moving information analysis image in which the count line and the count result of the number of moving objects having passed the count line in the predetermined transmission cycle are added to the background image, and
display the moving information analysis image on a monitor connected to the server.
12. The method of claim 11 further comprising:
causing the camera to generate the count line in response to an instruction from the server.
13. The method of claim 11 further comprising:
causing the camera to count a number of bidirectional moving objects on a direction basis as the count result with respect to the count line as a single count line, and
causing the server to generate the moving information analysis image displaying directions from which the moving objects have passed and the count result on a directional basis.
14. The method of claim 11 further comprising:
causing the camera to generate a plurality of count lines, and count a respective number of moving objects having passed each of the plurality of count lines as a respective count result, and
causing the server to generate the moving information analysis image displaying the plurality of count lines having different display aspects as the plurality of count lines and count results respectively corresponding to the plurality of count lines.
15. The method of claim 11 further comprising:
causing the camera to generates a plurality of count lines, and to count multiple numbers of moving objects having passed two or more of the plurality of count lines as the count result, and
causing the server to generate the moving information analysis image displaying the plurality of count lines having different display aspects as the count lines and multiple count results of the number of moving objects respectively corresponding to combinations of the plurality of count lines.
16. The method of claim 11 further comprising:
causing the server to generate the moving information analysis image displaying arrows having different thicknesses according to the number of moving objects having passed the count line.
