Abstract

As disclosed herein, a method for recognizing a previously-traveled route includes receiving recorded video data and a current video stream from one or more video capture devices, identifying one or more objects in the received video data to provide one or more recorded waypoints, identifying one or more visible objects in the received current video stream to provide one or more visible waypoints, comparing the visible waypoints to the recorded waypoints to provide one or more matching waypoints, and identifying a previously traveled path in the received current video stream corresponding to the one or more of the identified matching waypoints. A computer program product and computer system corresponding to the method are also disclosed.

Claims

1. A method comprising:

receiving recorded video data and a current video stream from one or more video capture devices;

identifying one or more objects in the received video data to provide one or more recorded waypoints;

identifying one or more visible objects in the received current video stream to provide one or more visible waypoints;

comparing the visible waypoints to the recorded waypoints to provide one or more matching waypoints; and

identifying a previously traveled path in the received current video stream corresponding to the one or more of the identified matching waypoints.

2. The method of claim 1, further comprising displaying one or more indicators on a display indicating the previously traveled path to a user.

3. The method of claim 1, wherein the one or more video capture devices include at least a front facing camera and a rear facing camera.

4. The method of claim 1, wherein identifying one or more visible objects in the received current video stream to provide one or more visible waypoints occurs responsive to receiving a user request to identify a previously traveled path.

5. The method of claim 1, further comprising identifying one or more potential previously traveled paths corresponding to the current video stream.

6. The method of claim 5, wherein identifying a previously traveled path in the received current video stream corresponding to the one or more identified matching waypoints comprises calculating a distance between the one or more identified matching waypoints and each of the currently displayed paths.

7. The method of claim 6, wherein identifying a previously traveled path in the received current video stream corresponding to the one or more identified matching waypoints comprises selecting the path corresponding to the smallest calculated distance to the identified one or more matching waypoints.

8. A computer program product comprising:

one or more computer readable storage media and program instructions stored on the one or more computer readable storage media, the program instructions comprising instructions to;

receive recorded video data and a current video stream from one or more video capture devices;

identify one or more objects in the received video data to provide one or more recorded waypoints;

identify one or more visible objects in the received current video stream to provide one or more visible waypoints;

compare the visible waypoints to the recorded waypoints to provide one or more matching waypoints; and

identify a previously traveled path in the received current video stream corresponding to the one or more of the identified matching waypoints.

9. The computer program product of claim 8, further comprising instructions to display one or more indicators on a display indicating the previously traveled path to a user.

10. The computer program product of claim 8, wherein the one or more video capture devices include at least a front facing camera and a rear facing camera.

11. The computer program product of claim 8, wherein identifying one or more visible objects in the received current video stream to provide one or more visible waypoints occurs responsive to receiving a user request to identify a previously traveled path.

12. The computer program product of claim 8, further comprising instructions to identify one or more potential previously traveled paths corresponding to the current video stream.

13. The computer program product of claim 12, wherein instructions to identify a previously traveled path in the received current video stream corresponding to the one or more identified matching waypoints comprise instructions to calculate a distance between the one or more identified matching waypoints and each of the currently displayed paths.

14. The computer program product of claim 13, wherein instructions to identify a previously traveled path in the received current video stream corresponding to the one or more identified matching waypoints comprise instructions to select the path corresponding to the smallest calculated distance to the identified one or more matching waypoints.

15. A computer system comprising:

one or more computer processors;

one or more computer-readable storage media;

program instructions stored on the computer-readable storage media for execution by at least one of the one or more processors, the program instructions comprising instructions to;

receive recorded video data and a current video stream from one or more video capture devices;

identify one or more objects in the received video data to provide one or more recorded waypoints;

identify one or more visible objects in the received current video stream to provide one or more visible waypoints;

compare the visible waypoints to the recorded waypoints to provide one or more matching waypoints; and

identify a previously traveled path in the received current video stream corresponding to the one or more of the identified matching waypoints.

16. The computer system of claim 15, further comprising instructions to display one or more indicators on a display indicating the previously traveled path to a user.

17. The computer system of claim 15, wherein identifying one or more visible objects in the received current video stream to provide one or more visible waypoints occurs responsive to receiving a user request to identify a previously traveled path.

18. The computer system of claim 15, further comprising instructions to identify one or more potential previously traveled paths corresponding to the current video stream.

19. The computer system of claim 18, wherein instructions to identify a previously traveled path in the received current video stream corresponding to the one or more identified matching waypoints comprise instructions to calculate a distance between the one or more identified matching waypoints and each of the currently displayed paths.

20. The computer system of claim 19, wherein instructions to identify a previously traveled path in the received current video stream corresponding to the one or more identified matching waypoints comprise instructions to select the path corresponding to the smallest calculated distance to the identified one or more matching waypoints.
