Measurement system, measurement method and non-transitory storage medium

A measurement method, executed by a computer, comprising:

• acquiring a plurality of pieces of captured image data generated by having one or more imaging devices, supported by a multi-axis robot, capture images at two or more positions;
• and
• measuring a distance between a plurality of feature points in a workpiece on the basis of a position of a feature point of the workpiece included in the plurality of pieces of captured image data, wherein
• during the measuring the distance, measuring a distance between i) a position of one end of the workpiece included in the captured image data generated by having the imaging device capture an image at a first position and ii) a position of the other end of the workpiece included in the captured image data generated by having the imaging device capture an image at a second position different from the first position, and measuring a length from one end to the other end of the workpiece by correcting a distance between a position of the one end of the workpiece and a position of the other end of the workpiece, on the basis of a relationship between i) a first distance from the imaging device to the feature point measured by a distance measurement device for measuring a distance from the imaging device to the feature point at the first position and ii) a second distance from the imaging device to the feature point measured by the distance measurement device at the second position.

A non-transitory storage medium storing a program for causing a computer to execute:

• acquiring a plurality of pieces of captured image data generated by having one or more imaging devices, supported by a multi-axis robot, capture images at two or more positions;
• and
• measuring a distance between a plurality of feature points in a workpiece on the basis of a position of a feature point of the workpiece included in the plurality of pieces of captured image data, wherein
• during the measuring the distance, measuring a distance between i) a position of one end of the workpiece included in the captured image data generated by having the imaging device capture an image at a first position and ii) a position of the other end of the workpiece included in the captured image data generated by having the imaging device capture an image at a second position different from the first position, and measuring a length from one end to the other end of the workpiece by correcting a distance between a position of the one end of the workpiece and a position of the other end of the workpiece, on the basis of a relationship between i) a first distance from the imaging device to the feature point measured by a distance measurement device for measuring a distance from the imaging device to the feature point at the first position and ii) a second distance from the imaging device to the feature point measured by the distance measurement device at the second position.
