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 (1D information) from the displacement sensor and a plurality of pieces of positional information from the drives that are read in accordance with a measurement range and a measurement interval (measurement recording position) defined by the PLC for measuring an object A, and generates 2D shape data.
Claims18
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 define a measurement range and a measurement interval for measuring the object, and 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 the defined measurement interval;
- 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.
A control method used by a control system 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:
- defining a measurement range and a measurement interval for measuring the object, and 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 the defined measurement interval;
- and
- generating two-dimensional shape data or three-dimensional shape data based on the obtained measurement data.
A non-transitory computer-readable recording medium storing a program for a control system 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 control system to perform operations comprising:
- defining a measurement range and a measurement interval for measuring the object, and 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 the defined measurement interval;
- and
- generating two-dimensional shape data or three-dimensional shape data based on the obtained measurement data.
