US12540794 - Automated vision-based orientation measurement system and method of use

A calibration assembly for a guided vehicle. The calibration assembly includes an orientation marker that operably engages with a first guidance apparatus of the guided vehicle. The calibration assembly also includes an imaging assembly that operably engages with and is in electrical communication with a second guidance apparatus of the guided vehicle. When the imaging assembly captures the orientation marker at a translated position for at least one cycle, the imaging assembly calibrates a rotational displacement between a first guidance direction of the first guidance apparatus and a second guidance direction of the second guidance apparatus based on an angular displacement of the orientation marker measured between a zeroed position denoting the first guidance direction and the translated position.

This patent describes a calibration assembly for guided vehicles that utilizes an orientation marker and an imaging assembly to measure and calibrate the rotational displacement between two guidance apparatuses. The system enhances accuracy by capturing the orientation marker’s position and adjusting based on the angular displacement from a predefined zeroed position.

Claim 1

1 . A calibration assembly for a guided vehicle, comprising: an orientation marker operably engaged with a first guidance apparatus of the guided vehicle; an imaging assembly operably engaged with and in electrical communication with a second guidance apparatus of the guided vehicle; wherein when the imaging assembly captures the orientation marker at a translated position for at least one cycle, the imaging assembly calibrates a rotational displacement between a first guidance direction of the first guidance apparatus and a second guidance direction of the second guidance apparatus based on an angular displacement of the orientation marker measured between a zeroed position denoting the first guidance direction and the translated position; and an orientation marker operably engaged with a first guidance apparatus of the guided vehicle; an imaging assembly operably engaged with and in electrical communication with a second guidance apparatus of the guided vehicle; wherein when the imaging assembly captures the orientation marker at a translated position for at least one cycle, the imaging assembly calibrates a rotational displacement between a first guidance direction of the first guidance apparatus and a second guidance direction of the second guidance apparatus based on an angular displacement of the orientation marker measured between a zeroed position denoting the first guidance direction and the translated position; and wherein the orientation marker comprises: a non-transitory computer readable medium facing at the imaging assembly and configured to store data about the first guidance apparatus. a non-transitory computer readable medium facing at the imaging assembly and configured to store data about the first guidance apparatus.
