Abstract
To provide a traffic monitoring apparatus capable of accurately determining the number of objects present in an area under surveillance without being affected by the difference in arrangement of those objects. Included is an object information acquiring device 1A for acquiring three-dimensional object information D related with an object H present in an area 8 under surveillance, and a determining device 2A for determining the number of objects based on at least a volume, which is one of a volume and a height of an object obtained from the object information D.
Claims10
A traffic monitoring apparatus which comprises:
- an object information acquiring device for acquiring three-dimensional object information related with an object present in an area under surveillance;
- and
- a determining device for determining the number of objects based on at least a volume, which is one of a volume and a height of an object obtained from the object information.
A traffic monitoring apparatus which comprises:
- an object information acquiring device for acquiring three-dimensional object information related with an object present in an area under surveillance;
- and
- a determining device for determining the number of objects based on a distribution, in a two-dimensional plane, of volumes of objects from the object information.
A traffic monitoring apparatus which comprises:
- an object information acquiring device for acquiring three-dimensional object information related with an object present in an area under surveillance;
- a first information generating device for generating a first quantitative information related with the number of objects based on at least the volume, which is one of a volume and a body height of an object obtained from the object information;
- a second information generating device for generating a second quantitative information related with the number of objects based on a distribution of the volumes of objects in a two-dimensional plane from the object information;
- and
- a determining device for determining the number of the objects based on the first and/or second quantitative information.
