[0002] Straightness measurement mainly measures the straightness error of the workpiece element line, the guide surface of machine tools and other machines, and the straightness error of the workpiece linear guide surface. Straightness measurement is one of the important contents of length measurement technology. In addition, the straightness error can also be measured using flat crystals, laser interferometers and their straightness measurement accessories, with high measurement accuracy.

[0003] In the existing related technologies, for the detection of the straightness of strip workpieces, a detection tool is usually set on a horizontal plane, and then a strip workpiece to be measured parallel to the detection tool is set. The strip workpiece is in contact with the detection tool (horizontal plane or vertical plane). As the detection tool slides, the straightness of the strip workpiece is measured through the data change of the detection tool. The parallelism between the strip workpiece to be measured and the detection tool cannot be guaranteed.
