Immersive surveillance system interface
View Patent ↗A surveillance system interface includes a displayed wide-angle image and a contemporaneously displayed narrower-angle image. The interface permits a user to select a view within the wide-angle image to indicate a region of interest. The narrower-angle image may then be made to correspond to the indicated region of interest.
1. A method for displaying video images, the method comprising:
receiving a first digital video signal corresponding to a captured wide-angle video image of an environment, said wide-angle video image having a field of view distorted relative to human perception and being navigable for selecting regions of the wide-angle video image to display;
collecting data points within the environment by collecting information relating to positions of a plurality of objects located within the environment;
storing the collected data points as correlation data in a storage device;
selecting an object of interest within the wide-angle field of view by performing a navigation of the wide-angle video image and selecting, based on a user input, the object of interest;
processing the first digital video signal to create a perspectively corrected video image corresponding to the selected object of interest;
receiving a second digital video signal corresponding to a second video image captured by a pan-tilt-zoom video camera, the second video image providing a view corresponding to the selected object of interest, the second video image further having been interpolated with the correlation data to correct parallax effects and correctly orient the pan-tilt-zoom video camera to the selected object of interest; and
contemporaneously displaying the perspectively corrected video image, and the second video image.
2. The method of claim 1 , wherein the user input is received through a pointing device.
3. The method of claim 1 , wherein the field of view of the wide-angle video image has an immersive field of view.
4. The method of claim 1 , wherein the step of contemporaneously displaying is performed on a single viewing device.
5. The method of claim 1 , the method further comprising:
processing the first digital video signal to create an equirectangular video image,
wherein the step of contemporaneously displaying further comprises contemporaneously displaying: the equirectangular video image.
6. The method of claim 5 , further comprising:
receiving user input relative the displayed equirectangular video image indicating the object of interest within the environment, the user input being a mouse click on the object of interest within the video image of the environment;
orienting the pan-tilt-zoom video camera to capture a video image corresponding to the object of interest indicated by the user input relative to the displayed equirectangular video image.
7. The method of claim 5 , wherein the field of view of the wide-angle video image is an immersive field of view.
8. The method of claim 5 , wherein the step of contemporaneously displaying is performed on a single viewing device.
9. A method for displaying video images, the method comprising:
displaying an equirectangular video image of an environment to a user;
collecting data points within the environment by collecting information relating to positions of a plurality of objects located within the environment;
storing the collected data points as correlation data in a storage device;
receiving user input performing navigation operations on the equirectangular video image selecting an object of interest within the environment relative to the displayed equirectangular video;
orienting a pan-tilt-zoom video camera to capture a video image corresponding to the object of interest indicated by the user input, the orientation of the pan-tilt-zoom video camera being determined by interpolating the selected object of interest with the correlation data to obtain parallax corrected orientation of the camera; and
displaying the captured video image obtained by the oriented pan-tilt-zoom video camera.
10. The method of claim 9 , wherein the user input is received through a pointing device.
11. The method of claim 10 , wherein the user moves the pointing device and selects the object of interest on the displayed equirectangular video image.
12. The method of claim 10 , wherein the received user input further indicates a selected field of view, and the step of orienting further comprises adjusting the level of zoom of the pan-tilt-zoom video camera to correspond to the selected field of view.
13. A method for displaying video images, the method comprising:
displaying a navigable perspectively corrected immersive video image of an environment to a user;
collecting data points within the environment by collecting information relating to positions of a plurality of objects located within the environment;
storing the collected data points as correlation data in a storage device;
receiving user input navigating the displayed navigable perspectively corrected immersive video image to select an object of interest within the environment;
orienting a pan-tilt-zoom video camera to capture a video image corresponding to the object of interest indicated by the user input, the orientation of the pan-tilt-zoom video camera being determined by interpolating the selected object of interest with the correlation data to obtain parallax corrected orientation of the camera; and
displaying the captured video image obtained by the oriented pan-tilt-zoom video camera.
14. The method of claim 13 , wherein the user input is received through a pointing device.
15. The method of claim 14 , wherein the user moves the pointing device and selects the object of interest on the displayed equirectangular video image.
