Method for Video-Data Indexing Using a Map
First Claim
1. A method that comprises the following steps for video-data indexing using a map:
- a. Video data are obtained from at least one camera.b. The video data are used to locate at least one moving object and to estimate the object position and/or motion parameters in the two-dimensional video frame coordinate system (the object position in the video frame).c. The position and/or motion parameters of the located object are converted from the two-dimensional frame coordinate system into the two-dimensional map coordinate system (the object position on the map).d. At least one index record is generated to relate the video data containing the located object to its position and/or motion parameters on the map.e. The index record is saved in the database and/or storage.

Abstract
The method for video-data indexing using a map comprises the following steps: video data are obtained from at least one camera; the video data are used to locate at least one moving object and to estimate the object position and/or motion parameters in a two-dimensional video frame coordinate system (the object position on the video frame); the position and/or motion parameters of the located object are converted from the two-dimensional frame coordinate system into a two-dimensional map coordinate system (the object position on the map); at least one index record is generated to relate the video data containing the located object to its position and/or motion parameters on the map; the index record is saved in the database and/or storage.
The invention accelerates and refines search requests for video data containing information about objects moving across the area under video surveillance.
