Abstract

An information processing device measures a position of the moving object, acquires success or failure information relating to success or failure of the position measurement, acquires at least one of histories, determines to interrupt driving control of the moving object, and decides, if the driving control of the moving object is determined to be interrupted, a restart method. The histories include a history of the position of the moving object, a driving history of the moving object, a history of illuminance around the moving object, and a history of a direction of an imaging element mounted in the moving object. The driving control of the moving object is interrupted on the basis of the success or failure information. The restart method restarts the driving control of the moving object on the basis of at least one of the histories.

First claim

What is claimed is:

1. An information processing device comprising:
at least one processor and at least one memory, cooperating to:
measure a position of a moving object while the moving object is moving based on an image around the moving object,
acquire success or failure information relating to success or failure of position measurement in the position measurement step based on illuminance around the moving object,
acquire information relating to a history of illuminance around the moving object,
determine to interrupt driving control of the moving object on basis of the success or failure information acquired in the success or failure information acquisition step, and
in a case where the moving object is determined to be interrupted, decide restarting the driving control of the moving object and move the moving object to a return position where the illuminance around the moving object was successful in the position measurement step.

2. The information processing device according to claim 1 , wherein the restarting the driving control of the moving object includes at least one of a return position which is a point for restarting the driving control of the moving object and a method of driving the moving object for returning to the return position.

3. The information processing device according to claim 2 , wherein the at least one processor and the at least one memory further cooperating to
present the restart method to a user.

4. The information processing device according to claim 3 , wherein the at least one processor and the at least one memory further cooperating to:
control driving of the moving object, and
execute the restart method decided by the at least one processor and the at least one memory or a restart method specified by the user.

5. The information processing device according to claim 1 , wherein the position measurement on the moving object using a captured image of the surroundings of the moving object.

6. The information processing device according to claim 5 , wherein the at least one processor and the at least one memory further cooperating to acquire a history of the captured image of the surroundings of the moving object.

7. The information processing device according to claim 6 , wherein the at least one processor and the at least one memory decide the restarting the driving control of the moving object on the basis of a result of matching between the history of the captured image and a current captured image.

8. The information processing device according to claim 1 , wherein the success or failure information includes reliability information relating to reliability of the position measurement.

9. The information processing device according to claim 8 , wherein the at least one processor and the at least one memory further acquire a history of the reliability information.

10. The information processing device according to claim 9 , wherein the at least one processor and the at least one memory further decide the restarting the driving control of the moving object on the basis of the history of the reliability information.

11. The information processing device according to claim 1 , wherein the information relating to the success or failure information relating to failure in position measurement is obtained from the history of illuminance around the moving object, and wherein movement method and return position to which the moving object is moved so that the illuminance around the moving object can be obtained appropriately.

12. A moving device comprising
at least one processor and at least one memory, cooperating to:
measure a position of a moving object while the moving object is moving based on an image around the moving object,
acquire success or failure information relating to success or failure of position measurement in the position measurement step based on illuminance around the moving object,
acquire information relating to a history of illuminance around the moving object for capturing image of the surroundings,
interrupt driving control of the moving object on the basis of the success or failure information acquired in the success or failure information acquisition step,
in a case where the moving object is determined to be interrupted, decide restarting the driving control of the moving object and move the moving object to a return position where the illuminance around the moving object was successful in the position measurement step, and
control movement of the moving object.

13. A non-transitory computer-readable storage medium configured to store a computer program comprising instructions for executing following operations:
measuring a position of a moving object while the moving object is moving based on an image around the moving object;
acquiring success or failure information relating to failure of position measurement in the position measurement step based on illuminance around the moving object;
acquiring information relating to a history of illuminance around the moving object;
determining to interrupt driving control of the moving object on the basis of the success or failure information acquired in the success or failure information acquisition step; and
in a case where determining determines that the driving control of the moving object is to be interrupted, deciding to restart the driving control of the moving object and moving the moving object to a return position where the illuminance around the moving object was successful in the position measurement step.

14. An information processing method comprising:
measuring a position of a moving object while the moving object is moving based on an image around the moving object;
acquiring success or failure information relating to success or failure of measuring the position based on illuminance around the moving object;
acquiring information relating to a history of illuminance around the moving object;
determining to interrupt driving control of the moving object on the basis of the success or failure information; and
in a case where determining determines that the driving control of the moving object is to be interrupted, deciding to restart the driving control of the moving object and moving the moving object to a return position where the illuminance around the moving object was successful in the position measurement step.
