Vision Utilities
Owning Palette: Vision and MotionInstalled With: NI Vision Development ModuleUse the Vision Utilities VIs to create and manipulate images in NI Vision.
| Subpalette | Description |
|---|---|
| Image Management |
Use the Image Management VIs to create and dispose of images, set and read attributes of an image, and copy one image to another. |
| Files |
Use the Files VIs to read, write, and retrieve image file information. The file formats NI Vision supports are BMP, TIFF, JPEG, JPEG2000, PNG, AIPD (internal file format), and AVI (for multiple images). |
| External Display |
Use the External Display VIs to do the following in an external display window: display an image, get and set ROIs, manipulate the floating ROI tools window, configure an ROI constructor window, and set up and use an image browser. |
| Region of Interest |
Use the Region of Interest VIs to focus processing and analysis on part of an image. The Region of Interest Conversion subpalette contains VIs convert machine vision point, line, rectangle, and annulus datatypes to or from a Region of Interest descriptor. |
| Image Manipulation |
Use the Image Manipulation VIs to modify an image. Use these VIs to resample an image; extract parts of an image; and rotate, shift, and unwrap images. |
| Pixel Manipulation |
Use the Pixel Manipulation VIs to modify specific areas of an image. Use these VIs to read and set pixel values in an image, read and set values along a row or column in an image, and fill the pixels in an image with a particular value. |
| Overlay |
Use the Overlay VIs to overlay figures, text, and bitmaps onto an image without destroying the image data. Use these VIs to overlay the results of your inspection application onto the images you inspected. |
| Calibration |
Use the Calibration VIs to spatially calibrate an image. Spatial calibration converts pixel coordinates to real-world coordinates while compensating for potential perspective errors or nonlinear distortions in your imaging system. |
| Color Utilities |
Use the Color Utilities VIs to manipulate the colors and color planes of an image. Use these VIs to extract different color planes from an image, replace the planes of a color image with new data, convert a color image into a 2D array and back, read and set pixel values in a color image, and convert pixel values from one color space to another. |
| Vision RT |
Use the Vision RT VIs to configure and control display settings for your RT system and to setup time-bounded operations within your application. |
