This chapter describes the properties available in the Measurement step and how they can be used to find markers in an image (for example, edges, circles and stripes) and to take measurements. The Measurement step can be used to measure the distances between sequential occurrences of markers. To measure the distance or angle between various geometric features, or to measure distances or angles between arbitrary positions (for example, blobs, edges, and expected locations), you can use the Metrology step.
