Abstract
A surveillance recording device using cameras extracts facial images and whole body images of a person from images shot by the cameras. A height is calculated from the whole body images. Retrieval information, including a facial image (best shot), is associated with images in a recording medium and recorded into a database. The recorded data are utilized as an index for later retrieval from the recording medium. Facial images are displayed in a list of thumbnails to make it easy to retrieve a target person on a thumbnail screen. The images are displayed together with a moving image of a target person.
Claims26
A surveillance recording device comprising:
- at least one camera for shooting a target space;
- an image recording and reproducing means for recording images shot by said cameras in a recording medium, and reproducing images from said recording medium;
- an essential image extracting means for extracting essential images of a person from said images shot by said cameras;
- and
- a retrieval information recording means for recording retrieval information including said essential images.
A surveillance recording device comprising:
- at least one camera for shooting a target space;
- an image recording and reproducing means for recording images shot by said cameras onto a recording medium and for reproducing images from said recording medium;
- a detection wall setting means for defining a detection wall for detecting entry of people into a target space;
- a collision detecting means for detecting whether or not a person has collided with said detection wall;
- said detection wall is a virtual wall composed of a plurality of voxels depending on positional relationship of said cameras;
- a thickness of said detection wall is set to be small with respect to a depth of said target space.
A surveillance recording device comprising:
- at least one camera for shooting a target space;
- an image recording and reproducing means for recording images shot by said cameras onto a recording medium and for reproducing images from said recording medium;
- an essential image extracting means for extracting essential images of an object from images shot by said cameras;
- and
- a retrieval information recording means for recording retrieval information including said essential images.
A surveillance recording method in which a target space is shot by cameras and shot images are recorded onto a recording medium, comprising:
- means for extracting essential images of an object from said images shot by said cameras;
- and
- means for retrieving information including said essential images associated with said images shot by said cameras and recorded.
A surveillance recording method in which a target space is shot by cameras and said shot images are recorded onto a recording medium, comprising:
- extracting essential images of a person from said images shot by said cameras, and retrieval information including said essential images associated with said images shot by said cameras and recorded.
A surveillance recording method further comprising:
- at least stereoscopically shooting a target space and recording shot images onto a recording medium;
- defining a virtual detection wall;
- said step of defining includes defining a virtual detection wall composed of a plurality of voxels depending on said positional relationship of said cameras;
- assigning a thickness to said virtual detection wall that is small with respect to a depth of said target space;
- and
- detecting an entry of a person into said target space by detecting whether or not said person has collided with said detection wall.
