Machine sensor calibration system

A sensor calibration system, comprising:

• a first sensor mounted on a first mobile machine and configured to sense a characteristic of an object at a worksite;
• a first positioning device configured to indicate a position of the first mobile machine at the worksite;
• a second sensor mounted on a second mobile machine and configured to sense the characteristic of the object;
• a second positioning device configured to indicate a position of the second mobile machine at the worksite;
• and
• a controller in communication with the first sensor, the second sensor, the first positioning device, and the second positioning device, the controller being configured to:
• compare the characteristic of the object as sensed by the first sensor when the first positioning device indicates the first mobile machine is at a first worksite location to the characteristic of the object as sensed by the second sensor when the second positioning device indicates the second mobile machine is at the first worksite location;
• and
• correct subsequent signals received from the first sensor based on the comparison.

A method of calibrating object sensing, the method comprising:

• sensing from a first mobile machine a characteristic of an object;
• sensing from a second mobile machine the characteristic of the object;
• comparing the characteristic of the object as sensed from the first mobile machine to the characteristic of the object as sensed from the second mobile machine;
• and
• correcting subsequent characteristics sensed from the first mobile machine based on the comparison.
