Buffer Zone EyeMeasure Probe The EyeMeasure probe is particularly useful and robust in situations of poor edge form, or when it is required or helpful to control the exact length and relative orientation of the point acquisition path. The EyeMeasure video probe: • Can be used with either the default auto teach, or the manual teach edge parameters • Attempts to find a continuous edge along a traced path • Can have its shape, length and rotational orientation modified using one of the buffer handles • Provides feature type intelligence for Lines, Circles, and Arcs when features are not explicitly requested • Is particularly useful for features with poor form such as having noisy edges, excess material or contamination, or interrupt features, e.g. a keyway. Inspection Example Images The following six video inspection images demonstrate a variety of edge conditions that may be encountered in typical vision inspection applications. These images will demonstrate the use and applicability of the terms and functions discussed above. Each image is followed by a description of the M3 Video Probe capability or optimization that was utilized to achieve successful acquisition of points on the edge in question.
High Edge Contrast and Uniform Edge Form The MeasureLogic probe is typically the ideal tool for high edge contrast applications. Strong edge contrast and consistent feature form are ideal for the automatic edge detection capability of this probe. The MeasureLogic probe can also be used in the alternative EyeMeasure mode. The default auto teach behavior of this probe is generally adequate for edges like the one pictured here.
Low Edge Contrast and Uniform Edge Form For edges with poor edge contrast, but with good edge form, the manual teach routine can be used to optimize the edge detection capability of the MeasureLogic probe. The consistent edge form makes the MeasureLogic probe a suitable probe choice for successful point acquisition in the sample shown here. The MeasureLogic probe can also be used in the EyeMeasure mode.
NOTE The manual teach procedure was described in detail earlier in this section.
