Abstract
Disclosed a normalized metadata generation device, and object occlusion detection device and method. A normalized metadata generation method includes generating a multi-ellipsoid based three-dimensional human model using perspective features of a plurality of two-dimensional images obtained by the multiple cameras, performing scene calibration based on the three-dimensional human model to normalize object information of the object included in the two-dimensional images, and generating normalized metadata of the object from the two-dimensional images on which the scene calibration is performed.
Claims26
A normalized metadata generation method, the method is performed by a metadata generation device of a multi-camera-based video surveillance system including different kinds of cameras, the method comprising:
- generating a multi-ellipsoid based three-dimensional (3D) human model using perspective features of a plurality of two-dimensional (2D) images obtained by the multiple cameras;
- performing scene calibration based on the three-dimensional human model to normalize object information of the object included in the two-dimensional images;
- and
- generating normalized metadata of the object from the two-dimensional images on which the scene calibration is performed.
A normalized metadata generation device for a multi-camera-based video surveillance system including different kinds of cameras, the device comprising:
- a memory configured to store instructions;
- and
- a processor configured to execute the instructions,
- wherein the instructions execute a normalized metadata generation method comprising:
- generating a multi-ellipsoid based three-dimensional (3D) human model using perspective features of a plurality of two-dimensional (2D) images obtained by the multiple cameras;
- performing a scene calibration based on the 3D human model to normalize object information of the object included in the 2D images;
- and
- generating normalized metadata of the object from the two-dimensional images on which the scene calibration is performed.
