Abstract
A PLC system includes a displacement sensor, drives, and a PLC. The PLC system obtains line measurement data including a plurality of pieces of measurement information or 1D information from the displacement sensor and a plurality of pieces of positional information from the drives that are read in accordance with measurement intervals, generates 2D shape data, and generates 2D shape data as 1D arrangement information for every measurement interval from combination line measurement data combining the 1D information and the positional information.
Claims14
A control system, comprising:
- a measurement device configured to obtain one-dimensional information about an object;
- a drive configured to change a relative position of the measurement device relative to the object;
- and
- a controller configured to control the measurement device and the drive to obtain information about a two-dimensional shape or a three-dimensional shape of the object based on the one-dimensional information obtained by the measurement device,
- the controller including
- a measurement data obtaining unit configured to obtain measurement data including a plurality of pieces of one-dimensional information from the measurement device and a plurality of pieces of positional information from the drive that are read in accordance with measurement intervals;
- and
- a shape data generation unit configured to generate two-dimensional shape data or three-dimensional shape data based on the measurement data obtained by the measurement data obtaining unit, wherein the shape data generation unit generates the shape data as one-dimensional arrangement information for every measurement interval from combination measurement data combining the one-dimensional information and the positional information.
A control method used by a controller for controlling a measurement device configured to obtain one-dimensional information about an object, and a drive configured to change a relative position of the measurement device relative to the object to obtain information about a two-dimensional shape or a three-dimensional shape of the object based on the one-dimensional information obtained by the measurement device, the method comprising:
- obtaining measurement data including a plurality of pieces of one-dimensional information from the measurement device and a plurality of pieces of positional information from the drive that are read in accordance with measurement intervals;
- and
- generating two-dimensional shape data or three-dimensional shape data based on the obtained measurement data, wherein generating the shape data includes generating the shape data as one-dimensional arrangement information for every measurement interval from combination measurement data combining the one-dimensional information and the positional information.
A non-transitory computer-readable recording medium storing a program for a controller that controls a measurement device configured to obtain one-dimensional information about an object, and a drive configured to change a relative position of the measurement device relative to the object to obtain information about a two-dimensional shape or a three-dimensional shape of the object based on the one-dimensional information obtained by the measurement device, the program causing a processor included in the controller to perform operations comprising:
- obtaining measurement data including a plurality of pieces of one-dimensional information from the measurement device and a plurality of pieces of positional information from the drive that are read in accordance with measurement intervals;
- and
- generating two-dimensional shape data or three-dimensional shape data based on the obtained measurement data, wherein generating the shape data includes generating the shape data as one-dimensional arrangement information for every measurement interval from combination measurement data combining the one-dimensional information and the positional information.
