Based on the provincial edge detection algorithm in the Vision Edition 8.5 release, engineers can smoothly determine the edges that are difficult to find, similar to the functionality of some web page detection applications. At the same time, they can safely find edges with 1/25 or higher pixel accuracy and higher reliability for noisy images; the new method will increase the accuracy by a factor of 10 compared to the past. For example, in an image with uniform noise and a noise amplitude of 10, the new edge detector can be used to reduce the maximum error from 4/10 pixels to 5/100 pixels. In addition, engineers can detect straight edges in the image, which helps them detect multiple lines of intersection in different directions in the image. The edge detector can also support calibration images and merge proofing information, including image distortion and the image itself as part of the edge detection process.
The Vision Development Module version 8.5 provides further support for the entire NI vision hardware platform and enables more accurate identification of 2-D barcodes. Currently, 2-D barcodes are the most common application in machine vision in the industry, and the vision development module supports 1-D and 2-D barcode interpretation and optical character recognition/detection of images, helping engineers to get older in the production process. Found errors in packaging and assembly. The module adds support for new barcodes, including coding methods that include product information: Quick Response Matrix Code (QR) and 2-D barcodes, as well as Pharmacode (pharmaceutical coding), which is widely used in the pharmaceutical industry.
The module also includes the Vision Assistant Express VI and the Vision Acquisition Express VI. The Vision Assistant Express VI transforms features developed in Vision Assistant, an intuitive environment for rapid prototyping of image processing, into a VI to simplify visual applications. Using the Vision Acquisition Express VI, engineers can capture images from any NI vision hardware, IEEE 1394, and Gigabit Ethernet cameras connected to standard ports, all in a simple menu interface. Using Vision Assistant Express VIs and Vision Acquisition Express VIs will make it easier to use programmable machine vision applications, saving development time and lowering barriers, allowing machine designers to take full advantage of LabVIEW's flexibility.
