Abstract
A sensor calibration system for a mobile machine is disclosed. The sensor calibration system may have a first calibration object positioned at a first worksite location, a second calibration object positioned at a second worksite location, and a plurality of sensors located onboard the mobile machine to detect the first and second calibration objects. The sensor calibration system may also have a controller in communication with the plurality of sensors. The controller may be configured to calibrate at least one of the plurality of sensors when the mobile machine is proximate the first worksite location, and to calibrate at least one other of the plurality of sensors when the mobile machine is proximate the second worksite location.
Claims20
A sensor calibration system for a mobile machine, comprising:
- a first calibration object positioned at a first worksite location;
- a second calibration object positioned at a second worksite location;
- a plurality of sensors located onboard the mobile machine and configured to detect the first and second calibration objects;
- and
- a controller in communication with the plurality of sensors, the controller being configured to trigger calibration of at least one of the plurality of sensors based on a proximity of the mobile machine to the first worksite location, and to trigger calibration of at least one other of the plurality of sensors based on a proximity of the mobile machine to the second worksite location.
A sensor calibration system for a mobile machine, comprising:
- a calibration object positioned at a worksite location where the mobile machine performs a primary task;
- at least one sensor located onboard the mobile machine and configured to detect the calibration object during a calibration operation;
- and
- a controller in communication with the at least one sensor and configured to:
- determine performance of the primary task;
- and
- initiate the calibration operation based on the performance determination.
A method of calibrating a sensor mounted on a mobile machine, the method comprising:
- determining performance of a primary task at a work location by the mobile machine;
- sensing characteristics of a calibration object located at the work location based on the performance determination of the primary task;
- and
- modifying subsequent sensing based on the sensed characteristics.
