Patent Document ID: 8941733
Application ID: 11995130

Base Claim:
1. Video retrieval system connectable to a plurality of surveillance cameras for monitoring a surroundings, the video retrieval system comprising: displaying means for displaying a graphical overall description of the surroundings under surveillance, whereby the graphical overall description comprises a plurality of monitored areas that are allocated to different surveillance cameras and whereby the graphical overall description is displayed in a single perspective view, and querying means comprising a graphical user interface configured to enable a user to formulate a trajectory-specific search query graphically and/or interactively on the graphical overall description, the search query adapted to retrieve data about a moving object in the surroundings with a matching trajectory, and wherein the graphical user interface enables users to draw any of the group consisting of lines, curves, circles, hand-drawn lines, a spline generated by a plurality of single interpolation points of the graphical overall description and any combination thereof, thereby formulating the search query, wherein the video retrieval system is characterized by merging means for merging object-related information of the video data of the plurality of cameras into object-related meta-data, and wherein the video retrieval system is characterized in that the merging means is realized to merge the video data into the overall description and to extract object-related meta-data from the overall description and/or to extract object-related information from the video data of the plurality of cameras and to link and/or merge the object-related information to generate the object-related meta-data.

Claim 8:
8. The video retrieval system as set forth in claim 1 , further comprising merging means for merging object-related information of video data from the plurality of cameras into object-related metadata, the object-related metadata comprising trajectory data or object-tracking information or both and described in global coordinates referring to the surroundings, wherein the querying means enables a user to formulate a trajectory-specific search query selected from the group consisting of trajectory-by-sketch query and trajectory-by-example query, wherein the matching trajectory is defined as a trajectory of a moving object that matches the trajectory-specific search query and wherein the querying means enables access to the object-related metadata in order to perform the search queries.
