Pattern tool confirms that the gasket is present and installed in the correct area.
Vision Sensor Tools
Vision technology plays an important role for even simple inspections
Vision tools are what ultimately set machine vision sensors apart from other sensors. Vision technology plays a very important role for even the most basic presence/absence inspections. Typical vision tools include pattern, pixel count, brightness, contrast, and edge tools. Notably, a vision sensor can inspect multiple targets within a single image, as well as perform multiple inspection types relying on different tools.
How to Use Vision Sensor Tools
Vision sensors can provide information beyond whether a part is simply present or absent. Using an array of vision tools, vision sensors can differentiate between colors, inspect multiple targets, and tolerate misalignment during inspections.
Brightness tool confirms the presence of all 10 capsules by showing the greatest delta between pass/fail areas.
High contrast in the target area indicates the presence of a diode.
Multiple edge tools measure pixels to detect a clean edge on a drill burr.
Pixel count tool confirms the presence of 13 separate hole punches within one target by determining pixel value.
Color pixel count tool confirms the integrity of packaging by identifying pixel values of colors trained in the region of interest.
