Create Presence Tool and Set Teaching Area

The Presence Tool checks the histogram of shapes. The histogram of brightness (level 1-256) of each pixel in the teaching area is calculated (frequency table) to be used as default information for the presence check. Set the brightness range corresponding to the shape to check and press the Calculate button to measure the area of the shape (Pixel Count) by detecting pixels corresponding to the set brightness range. Adjust the acceptance range (Tolerance) of the check based on measured area values to set the presence check.

No.	Item	Description
1	Add Presence Tool	Adds a Presence Tool to the Vision Tool List.
2	Edit	A setting window of the job selected from the Vision Tool List is displayed.
3	Delete	The selected job from the Vision Job List is deleted.
4	Move Teaching Area	Press and hold the arrow to move the teaching area.
5	Adjust Teaching Area Size	Press and hold the arrow to adjust the teaching area size.
6	Edit Job Name – Edit Window	A virtual keyboard is displayed, and the job name can be edited. Press the Apply button to apply the setting.
7	Calculate	Checks the histogram distribution of edges within the Presence Tool teaching area.
8	Histogram Min/Max Setting	Slide the horizontal Histogram Min/Max bar to adjust the detection level of desired edges. Presence check uses histogram check. A histogram is list of the distribution of brightness of pixels within a measurement area from 0 to 255. If the measurement area is completely white, the brighter area (255) value in the histogram becomes larger, and if the measurement area is completely black, the darker area (0) value becomes larger. You can adjust the range of pixels to the desired brightness using the blue button. If the button reaches the end points (0, 255), it obtains all pixel values within the measurement area. For example, positioning the blue button between 1 and 2 will only obtain pixels with brightness corresponding to 1 and 2. The tolerance is immediately applied when the button is pressed.
9	Area Tolerance Limit Setting	Enter the pixel value allowed within the detected area in the edit window. Values exceeding the value range entered are not detected. Area displays the number of pixels corresponding to the brightness value set using the blue button (0-255). If the value exceeds the Area Tolerance range, it is considered that the histogram is not similar, and the measurement fails. If a value exceeds the Test tolerance range, the inspection result outputs 0. Press the Apply button to apply the setting.
10	Apply	Applies Vision Job settings.
11	Cancel	Cancels Vision Job Tool settings.
