Abstract

An apparatus for providing a multi-video summary provides video summaries of a single object seen from different angles, the video summaries being generated based on videos of an overlapping area captured by a plurality of imaging devices in different field of views (FOVs). The overlapping area is an area where monitoring areas of the plurality of imaging devices overlap one another.

First claim

What is claimed is:

1. A method of providing a multi-video summary, the method comprising:
setting up a plurality of imaging devices to monitor, in different fields of view (FOVs), a plurality of areas comprising at least one overlapping area commonly monitored by the plurality of imaging devices, and capture a plurality of videos from the plurality of areas, respectively, wherein the different FOVs of the plurality of imaging devices are at least vertically different from each other;
storing overlapping information in which the plurality of imaging devices and the at least one overlapping area are mapped to one another to indicate that objects respectively detected in the at least one overlapping area by the plurality of imaging devices are identical to one another; and
providing at least two video summaries which are generated from the plurality of videos and display at least two images of an identical object in the at least one overlapping area captured by at least two imaging devices among the plurality of imaging devices in the different FOVs, based on the overlapping information,
wherein the at least two video summaries are provided in one of:
a video display mode displaying a first video summary of a first video captured by at least one first imaging device and a second video summary of a second video only for the at least one overlapping area captured by a second imaging device;
a data display mode displaying the first video summary and a notification message indicating presence of a video clip for the at least one overlapping area captured by the second imaging device or information about the second imaging device; and
a video and data display mode displaying the first video summary and the second video summary along with the notification message.

2. The method of claim 1 , wherein the providing the two video summaries comprises displaying, on a single screen of a display, the two video summaries which respectively show at least one image of the object detected in the at least one overlapping area, the two video summaries being generated from at least two videos captured by the two imaging devices.

3. The method of claim 2 , wherein, when the two video summaries are displayed on the single screen, the two video summaries are synchronized in time to indicate that an image of the object shown in a first video summary and an image of the object shown in a second video summary are captured at a same time.

4. The method of claim 1 , further comprising displaying, on a single screen of a display, a first video summary which shows a plurality of first images of the object detected in the at least one overlapping area by a first imaging device with a first FOV; and
displaying at least one second video summary comprising at least one second image of the object detected in the at least one overlapping area by at least one second imaging device with at least one second FOV, in response to selecting at least one image of the first images or indication of the image of the first images.

5. The method of claim 4 , wherein the selected image of the first images and the second image are captured by the first imaging device and the second imaging device, respectively, at the same time.

6. The method of claim 4 , further comprising indicating presence of the second image of the object captured by the second imaging device in a storage when the first video summary is displayed.

7. The method of claim 6 , wherein the presence of the second image is indicated by at least one of information about a number of the second imaging device that captures a video of the at least one overlapping area and information about identifiers of the second imaging device that captures the video of the at least one overlapping area.

8. The method of claim 1 , wherein the two video summaries are provided by mapping a first video summary of the at least one overlapping area generated by a first imaging device among the plurality of imaging devices to at least one second video summary of the at least one overlapping area generated by at least one second imaging device among the plurality of imaging devices based on time stamp information.

9. The method of claim 1 , further comprising, in response to selecting an image included in a first video summary of the two video summaries, displaying an original video among the plurality of videos, corresponding to the image, captured by a first imaging device among the plurality of imaging devices.

10. A multi-video summary providing apparatus comprising:
a field of view (FOV) information storage configured to store information about at least one overlapping area commonly monitored by a plurality of imaging devices among a plurality of areas monitored by the plurality of imaging devices having different FOVs about the at least one overlapping area, wherein the different FOVs of the plurality of imaging devices are at least vertically different from each other; and
at least one processor configured to implement:
a mapping unit configured to store overlapping information in which the plurality of imaging devices and the at least one overlapping area are mapped to one another to indicate that objects respectively detected in the at least one overlapping area by the plurality of imaging devices are identical to one another; and
a multi-video summary provider configured to provide at least two video summaries which are generated from videos and display at least two images of an identical object in the at least one overlapping area captured by at least two imaging devices among the plurality of imaging devices in the different FOVs, based on the overlapping information,

wherein the at least two video summaries are provided in one of:
a video display mode displaying a first video summary of a first video captured by at least one first imaging device and a second video summary of a second video only for the at least one overlapping area captured by a second imaging device;
a data display mode displaying the first video summary and a notification message indicating presence of a video clip for the at least one overlapping area captured by the second imaging device or information about the second imaging device; and
a video and data display mode displaying the first video summary and the second video summary along with the notification message.

11. The apparatus of claim 10 , wherein the multi-video summary provider is configured to display, on a single screen of a display, the two video summaries which respectively show at least one image of the object detected in the at least one overlapping area, the two video summaries being generated from at least two videos captured by the two imaging devices.

12. The apparatus of claim 11 , wherein, when the two video summaries are displayed on the single screen, the multi-video summary provider is configured to synchronize the two video summaries in time to indicate that an image of the object shown in a first video summary and an image of the object shown in a second video summary are captured at a same time.

13. The apparatus of claim 10 , wherein the multi-video summary provider is configured to display, on a single screen of a display, a first video summary which shows a plurality of first images of the object detected in the at least one overlapping area by a first imaging device with a first FOV, and at least one second video summary comprising at least one second image of the object detected in the at least one overlapping area by at least one second imaging device with at least one second FOV, in response to at least one image of the first images or indication of the image of the first images.
