本节主题
Vision function Measurement is a powerful and highly accurate instrument for measuring distances and object dimensions. Edges along lines or circle segments are measured with subpixel accuracy. This makes it possible to precisely determine distances and radii for quality control or for positioning and tracking tasks in mechanical gripping systems.
For an overview of the registers used by Measurement, see section Overview of registers.
