Mobile object combination detection apparatus and method
First Claim
1. A mobile object combination detection apparatus comprising:
- a plurality of moving image input means;
a plurality of mobile object detection means each connected to one of said moving image input means; and
combination determination means;
wherein each of said plurality of mobile object detection means detects a mobile object at a predetermined position on a moving image inputted thereto from said moving image input means as changing information of a predetermined area within an image from said moving image input means, and sends the changing information as detection information to said combination determination means; and
said combination determination means combines said changing information as the detection information sent from said mobile object detection means and compares the detection information on the mobile object sent thereto from each of said mobile object detection means with a predetermined condition to determine that a target mobile object is detected when said detection information satisfies said predetermined condition;
wherein said plurality of moving image input means are all connected to a single moving image camera to input the same moving image; and
each of said mobile object detection means detects a mobile object at a different position on the same moving image inputted thereto from said moving image input means.

Abstract
A mobile object combination detection apparatus includes a plurality of moving image input units, a plurality of mobile object detection units each connected to one of the moving image input units, and a combination determination unit. Each of the plurality of mobile object detection unit detects a mobile object at a predetermined position on a moving image inputted thereto from the moving image input unit, and sends detection information to the combination determination unit. The combination determination unit compares the detection information of the mobile object sent thereto from each of the mobile object detection unit with a predetermined condition to determine that a target mobile object is detected when the detection information satisfies the predetermined condition.

2. A mobile object counting apparatus comprising:
-
a moving image camera;
two moving image input means connected to said moving image camera;
two mobile object detection means each connected to one of said moving image input means; and
combination determination means, wherein said two mobile object detection means each detect a mobile object at corresponding one of positions of two vertical slits, arranged in parallel with each other, on a moving image inputted thereto from said moving image input means, and respectively send a slit identifier, detection time and an image at the slit at the time of detection to said combination determination means; and
said combination determination means recognizes that the same mobile object has passed said two slits, calculates a moving direction and a moving speed of said mobile object, and counts the number of passing mobile objects based on the slit identifiers, detection times of mobile objects, and images at the slits at the time of detection sent thereto from said two mobile object detection means.

3. A tracking apparatus comprising:
-
a moving image camera;
a plurality of moving image input means connected to said moving image camera;
a plurality of mobile object detection means each connected to one of said plurality of moving image input means; and
combination determination means, wherein said plurality of mobile object detection means each detect a mobile object at each of a plurality of vertical slit positions and a plurality of horizontal slit positions on a moving image inputted thereto from said moving image input means, said vertical slits and said horizontal slits being arranged in lattice, and said plurality of mobile object detection means each send a slit position identifier and detection time of a mobile object to said combination determination means; and
said combination determination means identifies which of intersections of said lattice-like slits a mobile object has invaded, based on the slit position identifiers and detection times of mobile objects sent thereto from said mobile object detection means, and outputs the position of the mobile object on said moving image, and the size of the mobile object as information for use in tracking.
