Abstract

Methods, apparatuses and computer-readable media for creating a spatial bookmark are provided. A method includes performing an action at a near location which causes a spatial bearing parameter corresponding to a real-time video image captured by a video-camera platform at a remote location to be stored in a computer-readable memory, wherein the video-camera platform has a controllable LOS. Performing an action at the near location that designates to a computer an image displayed on a screen, wherein the image is representative of the real-time video image, thereby causing the computer to retrieve the spatial bearing parameter from the computer-readable memory, and performing an action causing the computer to aim the video-camera platform along a LOS, wherein the video-camera platform captures a real-time video image that is received at a screen for display at the near location.

Claims

1. A method comprising:

performing an action at a near location to specify an angular range of motion of a video camera platform and a number of divisions within the angular range of motion;

performing an action at the near location which causes at least one spatial bookmark, each comprising a spatial bearing parameter, corresponding to a real-time video image captured by the video-camera platform at a remote location, to be stored in a computer-readable memory, the video-camera platform having a controllable line-of-sight (LOS), wherein the at least one spatial bookmark is automatically created by the video-camera platform based on a scan of the specified angular range of motion and the specified number of divisions to provide a spatial bookmark for each of the divisions;

performing an action at the near location that designates to a computer an image displayed on a screen, wherein the image is representative of the real-time video image, thereby causing the computer to retrieve one of the at least one spatial bookmark from the computer-readable memory; and

performing an action causing the computer to aim the video-camera platform along a LOS corresponding to the one of the at least one spatial bookmark, wherein the video-camera platform captures a real-time video image that is received at a screen for display at the near location.

2. The method of claim 1, wherein the video-camera platform is in communication with a robotic device at the remote location, and wherein performing the action causing the computer to aim the video-camera platform along the LOS causes the robotic device to perform an action based on a real-time video image captured by the video-camera platform along the LOS.

3. The method of claim 1, wherein the video-camera platform is in communication with a computer application, and wherein performing the action causing the computer to aim the video-camera platform along the LOS causes the computer application to perform an action based on a real-time video image captured by the video-camera platform along the LOS.

4. The method of claim 1, wherein the spatial bearing parameter comprises at least one of a pan coordinate and a tilt coordinate.

5. The method of claim 1, further comprising automatically determining the at least one spatial bookmark based on one of a detected sensor signal at the remote location or user-selected scanning criteria.

6. The method of claim 1, wherein the image is one of a computer display icon and a representation of a real-time video image of the video-camera platform.

7. The method of claim 1, further comprising one of:

causing information indicative of the at least one spatial bookmark to be stored in the computer-readable memory; and

causing the information indicative of the one of the at least one spatial bookmark to be transmitted, wherein the information indicative of the one of the at least one spatial bookmark causes the video-camera platform to aim along a LOS corresponding to the one of the at least one spatial bookmark.

8. The method of claim 1, further comprising:

upon user-selection, storing an index of information indicative of the at least one spatial bookmark and transmitting the index along with an instruction to record the at least one spatial bookmark; and

upon the designation of the image, transmitting the index that corresponds to the at least one spatial bookmark to the remote location.

9. The method of claim 1, further comprising:

upon user-selection, storing the at least one spatial bookmark at the near location; and

upon the designation of the image, transmitting the at least one spatial bookmark to the remote location.

10. The method of claim 1, further comprising transmitting, from the near location, control signals for aiming the video-camera platform along the selected LOS.

11. A method comprising:

displaying, at a near location, real-time video images captured by a video-camera platform at a remote location, the video-camera platform having a controllable line-of-sight (LOS);

receiving one or more user-generated inputs at respective view-selection times while displaying the real-time video images, wherein the one or more user-generated inputs specify an angular range of motion of the video camera platform and a number of divisions within the angular range of motion;

recording at least one spatial bookmark, each comprising a spatial bearing parameter of the video-camera platform, obtained at each respective view-selection time in response to the respective user-generated inputs, wherein the at least one spatial bookmark is automatically created by the video-camera platform based on a scan of the specified angular range of motion and the specified number of divisions to provide a spatial bookmark for each of the divisions;

displaying images representative of the real-time video images at each view-selection time; and

automatically aiming the video-camera platform along a LOS corresponding to one of the at least one spatial bookmark in response to at least one user-generated input that designates a selected one of the images representative of the real-time video images.

12. The method of claim 11, wherein the one or more user-generated inputs comprise one of a mouse click or a touch-sensitive screen touch.

13. The method of claim 11, wherein the images representative of the dynamic view comprise one of computer display icons or miniature, static screen captures of selected video-camera platform views.

14. The method of claim 11, wherein the dynamic view captured by the video-camera platform is displayed in real-time.

15. The method of claim 11, wherein automatically aiming comprises transmitting a message to the remote location that causes the video-camera platform to be aimed along the recorded LOS corresponding to the selected one of the images.

16. A non-transitory computer-readable medium having computer program instructions stored thereon, which, when executed on a processor, cause the processor to perform a method comprising:

performing an action at a near location to specify an angular range of motion of a video camera platform and a number of divisions within the angular range of motion;

performing an action at the near location which causes at least one spatial bookmark, each comprising a spatial bearing parameter, corresponding to a real-time video image captured by the video-camera platform at a remote location, to be stored in a computer-readable memory, the video-camera platform having a controllable line-of-sight (LOS), wherein the at least one spatial bookmark is automatically created by the video-camera platform based on a scan of the specified angular range of motion and the specified number of divisions to provide a spatial bookmark for each of the divisions;

performing an action at the near location that designates to a computer an image displayed on a screen, wherein the image is representative of the real-time video image, thereby causing the computer to retrieve one of the at least one spatial bookmark from the computer-readable memory; and

performing an action causing the computer to aim the video-camera platform along a LOS corresponding to the one of the at least one spatial bookmark, wherein the video-camera platform captures a real-time video image that is received at a screen for display at the near location.
