Imaging and Machine Vision Specialists Integrates into National Instruments (NI) LabVIEW Environment
Nashua, NH (WiredPRNews.com) Based on the Alacron Fastmotion Library, the Alacron Vision Virtual Instruments – or VI’s – provide methods to integrate Alacron Frame Grabbers into the National Instruments (NI) LabVIEW environment. With Alacron Frame Grabbers and the Alacron Vision VI’s, users can control camera operations and manage images in array lists. These image lists are compatible with the NI Vision Image reference and therefore can be modified, displayed, archived, or can be used as input to other devices. These VI’s are supported in the National Instruments LabVIEW 8.5 environment when installed on the Microsoft Windows XP or Vista operating systems.
As part of their operations these IV’s retrieve the previous camera cap file used from the Windows registry. This file string will only be available only if this VI has been executed previously. If the previous camera cap file string is valid and the “Use Camera from Previous Session” check box is checked, this file string is sent to the Camera File String output. When VI executes correctly, no error will appear and the selected camera cap file path will be saved to the registry as the previous camera cap file used. The Camera File String output is a filename and path that describes the location of the user selected camera configuration file.
The system also offers capabilities that takes aCam Handle, Start Index, Number of Images, Error, and Image List as inputs and provides a Cam Handle, Error and Image List as outputs. The Update Image List VI updates the image list with images from the framegrabber starting at the beginning of the list or at the Start Index value provided at the input terminal. To update the image list from the start of the last grab or single shot, wire the output of the Alacron Get Last Image Index VI to the Start Index value input terminal of this VI. The Number of Images input terminal will cause the VI to update a subset of the image list or all images if this terminal is unwired or set to 0. If no error condition has been detected, the output image list will contain updated images from the framegrabber.
