Description

A video search interface device capable of efficiently searching a plurality of recorded video channels {Video search interfacing apparatus for searching a plurality of recording video channel}

The present invention relates to a recorded video search technology, and more particularly, to a video search interface device capable of efficiently searching a plurality of recorded video channels.

Surveillance cameras are installed and operated in various places where security is required. The number of such surveillance cameras installed is rapidly increasing every year, and the number of recording channels that users need to search for is also rapidly increasing. Accordingly, the importance of a technique for efficiently searching for a plurality of recorded video channels is further emphasized.

When an incident such as theft, loss, or crime occurs, a search is performed using the recorded video playback function using the surveillance camera. , it is not intuitive to limit the event-related camera, and the process of tracking the movement of the object of interest takes a lot of effort and time.

In order for the recorded video to be perfect evidence, it is necessary to check and collect the recorded video of all the movement lines of the object of interest. If the playback point has to be moved every time, it takes a lot of work as the number of channels increases.

In Republic of Korea Patent Publication No. 10-2019-0092227 (2019.08.07), a real image and recorded image search system by intelligent image analysis is proposed. This technology classifies and stores each CCTV image by channel, and applies a preset image analysis condition to the CCTV images of a plurality of CCTV cameras to simultaneously analyze images of multiple channels. Accordingly, multi-channel simultaneous search is possible by searching for a search condition set as an event in the captured CCTV image, and unnecessary manpower and time consumption can be prevented.

Such conventional recorded image search techniques are not intuitive because they are techniques for searching recorded images based on an event. Accordingly, the present inventor can search multiple recorded video channels more intuitively by generating a search history by selecting cameras in time series according to the movement path of the object of interest on a map in which the physical locations of the multiple cameras are visually arranged. Research was done on the technology to make it happen.

If an object of interest escapes from the location of the second camera at 20:10:28 while the video recorded by the second camera is played back on February 04, 2020, 20:10:25, the user can use the user manipulation to Ends playback of the second camera. Through this process, the history management unit 120 selects the cameras to reproduce the recorded image on the map displayed on the first area 210 of the screen 200 by the map display unit 110 in time series according to the movement line of the object of interest. The selected, time-sequentially selected cameras and search histories including their reproduction times are displayed and registered on the second area 220 of the screen 200 .

The image reproducing unit 130 reproduces the recorded image captured by the selected camera from the search history that is displayed and registered in the second area 220 of the screen 200 by the history management unit 120 to the third of the screen 200 . The area 230 is reproduced from the reproduction time point.

That is, the image reproducing unit 130 reproduces a recorded image captured by a camera selected to be reproduced from the search history list registered in the search history or when the search history is registered in the third area 230 of the screen 200 from the playback time point.

For example, if the user double-clicks the third area 230 of the screen 200, the recorded image captured by the camera selected for playback is converted to full screen and displayed, and when the user double-clicks the full screen, the It may be implemented to be displayed through the third area 230 .

The controller 140 controls the overall device including the map display control of the map display unit 110 , the search history registration control of the history management unit 120 , and the recorded image reproduction control of the image reproducing unit 130 .

The user can more intuitively search for a plurality of recorded video channels through the search history displayed and registered in the second area 220 of the screen 200 by the history management unit 120, and the recorded video selected from the search history is displayed It can be confirmed by playing through the playback unit 130 .
