User manual OMRON XPECTIA FZ3

[. . . ] Z291-E1-0 Xpectia Series FZ3 Vision Sensor Processing Items List USERS MANUAL Introduction Thank you for purchasing the FZ3 Series. This manual provides information regarding functions, performance and operating methods that are required for using the FZ3 Series. When using the FZ3 Series, be sure to observe the following: · The FZ3 Series must be operated by personnel knowledgeable in electrical engineering. · To ensure correct use, please read this manual thoroughly to deepen your understanding of the product. [. . . ] The binary level is not held constant. Stable binary images can be obtained by taking the difference between the input image and that input image after it has been subject to brightness averaging. This option is effective when the lighting is unstable. Binary kind Dyn threshold 3. In the "Binary setting" area, specify the reference density range. When binarization is selected 194 Labeling+ FZ3 Processing Items List Manual Setting item Upper limit Binary level Lower limit Set value [Factory default] 0 to 255 [255] 0 to 255 [128] -- Description Specify the level for converting 256-tone grayscale images to binary images. Adjust the binary level so that the measurement object is converted to white pixels. You can also set the binary level so that only intermediate density is measured. Optimum binary levels are calculated automatically and set. 2 Measurement Auto setting Reverse Checked [Unchecked] This item reverses black and white colors. When Dyn threshold is selected Setting item Set value [Factory default] 0 to 127 [5] Description This sets the offset for the difference between the input image and that input image after it has been subject to brightness averaging. The higher this value, the easier it is to extract locations (such as edges) with large density difference. This item reverses black and white colors. Offset value Reverse Checked [Unchecked] Perform the [Detail setting] if required. FZ3 Processing Items List Manual Labeling+ 195 Setting item Set value [Factory default] Description Set the region to extract. Light: Pixels brighter than the pixels around them are treated as white pixels. Dark: Pixels darker than the pixels around them are treated as white pixels. Equal: Pixels with minimum density difference from the pixels around them are treated as white pixels. Not equal: Pixels with large density difference from the pixels around them are treated as white pixels. Specify the filter size for brightness averaging processing. Match this size to the size of the location you want to extract. This sets the offset for the difference between the input image and that input image after it has been subject to brightness averaging. The higher this value, the easier it is to extract locations (such as edges) with large density difference. This item reverses black and white colors. 2 Measurement Threshold region [Light] Dark Equal Not equal Filter size 3 to [255] Offset value 0 to 127 [5] Reverse Checked [Unchecked] Region Setting (Labeling+) This item is used to set up the measurement area. It is possible to measure the entire input image, but restricting the range enables accurate measurement in a short period of time. Use a rectangle, straight line, circle (ellipse), wide circle, or polygon to specify a measurement region for [Labeling+]. 1. The measurement region is registered and displayed in the Image Display area. 196 Labeling+ FZ3 Processing Items List Manual 5. If necessary, in the "Display setting" area, set up display settings for the images displayed in the Image Display area. For color cameras: 2 Measurement Setting item Extract image Set value [Factory default] Description If you place a check at this option, images set with color specification are displayed. [Checked] Unchecked For monochrome cameras: Setting item Set value [Factory default] Description The image is displayed in binary with black and white. Binary image [Checked] Unchecked Reference Position (Labeling+) This item can be changed if necessary. When the region is set, the reference position is automatically set at the center of gravity of the measurement region. In the same way for the reference area, when the region settings are made, they are set automatically based on the measurement region. This item can be used to change the reference position to any desired position. 1. In the Image Display area, the current reference position will be displayed as the crosshair cursor. Tap the position to be set as the reference position. FZ3 Processing Items List Manual Labeling+ 197 Note Displaying the image enlarged makes this tapping easier. Reference: "Using the Zoom Function" in the "User's Manual" (p. 317) 3. If necessary, finely adjust with numeric input and the arrow buttons. When changing the registered angle, adjust the reference angle. 2 Measurement 4. If necessary, in the "Display setting" area, set up display settings for the images displayed in the Image Display area. For color cameras: Setting item Extract image Set value [Factory default] Description If you place a check at this option, images set with color specification are displayed. [Checked] Unchecked For monochrome cameras: Setting item Set value [Factory default] Description The image is displayed in binary with black and white. Binary image [Checked] Unchecked Extraction Conditions (Labeling+) Set the conditions for extraction as a label. Extraction conditions can be changed as needed to address unstable measurement results or for faster processing. Normally, the factory default value will be used. 1. Set the value of each item in the "Filtering" area. 198 Labeling+ FZ3 Processing Items List Manual Setting item Set value [Factory default] Description Select the process method for the part encircled by the designated color circle. [. . . ] Set the judgement mode in the "NG settings" area. Setting item Set value [factory default] [One NG] Description The image is saved even if only one of the judgement criteria set using "Judgement expression" has a judgement of NG. The image is saved if all of the judgement criteria set using "Judgement expression" have a judgement of NG. Judgement mode All NG FZ3 Processing Items List Manual Display Last NG Image 429 Expression Settings The measurement details used for NG judgement are set using an expressions. 1.
