Abstract
A traffic density analysis apparatus comprising a video decoder section configured to decode encoded video data obtained by encoding a video signal corresponding to an analysis region and output a decoded video signal, and an analyzer section configured to set a specific region in a screen using the decoded video signal output from the video decoder section and analyze a traffic density in the analysis region from information related to a moving object which passes through the specific region.
Claims15
A traffic density analysis apparatus comprising:
- a video decoder section which decodes encoded video data obtained by encoding a video signal corresponding to an analysis region and outputs a decoded video signal;
- and
- an analyzer section which sets a specific region in a screen using the decoded video signal output from said video decoder section and analyzes a traffic density in the analysis region from information included in the decoded video signal and related to a moving object which passes through the specific region.
A traffic density analysis apparatus comprising:
- a video encoder section which encodes a video signal corresponding to an analysis region and outputs encoded video data;
- and
- an analyzer section which sets a specific region in a screen using a local decoded signal generated by said video encoder section and analyzes a traffic density in the analysis region from information related to a moving object which passes through the specific region.
A traffic information system comprising:
- at least one monitor camera section which encodes a video signal obtained by capturing an image in a monitoring region to be monitored for a traffic density and outputs encoded video data;
- at least one terminal section which requests traffic information and receives the traffic information;
- and
- a monitor center comprising a video decoder which decodes the encoded video data corresponding to the image captured by each of said monitor camera sections, an analyzer section which sets a specific region in a scene using the decoded video signal and analyzes a traffic density in the monitoring region, based on information related to a moving object which passes through the specific region, and a transmission section which transmits traffic information including the traffic density and video information in response to a request of said terminal section.
