Abstract
The present disclosure relates to a mobile body, a calibration method, and a program capable of eliminating mismatch between user calibration and calibration check. A calibration check unit executes a second calibration check to which a calibration parameter obtained by calibration of a stereo camera is applied, using a deviation detection image in which a calibration deviation is detected in a first calibration check of the stereo camera executed during the movement of a self device. The technology according to the present disclosure can be applied to, for example, a drone equipped with a stereo camera.
Claims16
A mobile body comprising:
- a stereo camera;
- an image saving unit that saves a deviation detection image in which a calibration deviation is detected in a first calibration check of the stereo camera executed during movement of the mobile body;
- and
- a calibration check unit that uses the deviation detection image to execute a second calibration check to which a calibration parameter obtained by calibration of the stereo camera is applied.
A calibration method comprising, by a mobile body including a stereo camera:
- saving a deviation detection image in which a calibration deviation is detected in a first calibration check of the stereo camera executed during movement of the mobile body;
- and
- using the deviation detection image to execute a second calibration check to which a calibration parameter obtained by calibration of the stereo camera is applied.
A program for causing a computer to execute processing of:
- saving a deviation detection image in which a calibration deviation is detected in a first calibration check of a stereo camera executed during movement of the mobile body including the stereo camera;
- and
- using the deviation detection image to execute a second calibration check to which a calibration parameter obtained by calibration of the stereo camera is applied.
