Abstract
A data processing device processes measurement data measured by a sensor that measures three-dimensional coordinates of a measurement object from a first position and a second position which are different. The data processing device includes a controller. The controller acquires measurement data of three or more planes of the measurement object from the sensor, the planes having different normal vectors. The controller finds, from the acquired measurement data, a transformation expression that integrates a coordinate system of the sensor at the second position into a coordinate system of the sensor at the first position.
Claims11
A data processing device that processes measurement data measured by a sensor that measures three-dimensional coordinates of a measurement object from a first position and a second position which are different, comprising:
- a controller that:
- acquires measurement data of three or more planes of the measurement object from the sensor, the planes having different normal vectors as a result of a change of orientation of the measurement object relative to the sensor, and
- finds, from the acquired measurement data, a transformation expression that integrates a coordinate system of the sensor at the second position into a coordinate system of the sensor at the first position;
- wherein during operation, the measurement object is moved, and wherein a visual field of the sensor at the first position and a visual field of the sensor at the second position overlap.
A data processing method of processing measurement data measured by a sensor which measures three-dimensional coordinates of a measurement object from a first position and a second position which are different, the method comprising:
- acquiring the measurement data of three or more planes of the measurement object from the sensor, the planes having different normal vectors as a result of a change of orientation of the measurement object relative to the sensor;
- and
- finding, from the acquired measurement data, a transformation expression that integrates a coordinate system of the sensor at the second position into a coordinate system of the sensor at the first position;
- wherein during operation, the measurement object is moved, and wherein a visual field of the sensor at the first position and a visual field of the sensor at the second position overlap.
A recording medium that stores a program which makes a computer of a data processing device function as a controller, the data processing device processing measurement data measured by a sensor that measures three-dimensional coordinates of a measurement object from a first position and a second position which are different,
- wherein the controller:
- acquires the measurement data of three or more planes of the measurement object from the sensor, the planes having different normal vectors as a result of a change of orientation of the measurement object relative to the sensor;
- and
- finds, from the acquired measurement data, a transformation expression that integrates a coordinate system of the sensor at the second position into a coordinate system of the sensor at the first position;
- wherein during operation, the measurement object is moved, and wherein a visual field of the sensor at the first position and a visual field of the sensor at the second position overlap.
