Windows系统下（Linux和MAC系统下请自行了解清楚）NI的各种软件、模块、工具包、驱动程序，使用NI许可证管理器来激活的，绝大部分的都可以使用NI Lincense Activator来激活：NI序列号Serial Number生成激活工具NI License Activator，LabVIEW/VBAI/VDM/VAS等软件模块工具包破解工具不限版本http://pcmv.cn/thread-490-1-1.html

视觉论坛的各种NI资源，除了视觉相关的模块有使用外，大部分的都不会使用，仅提供资源不提供技术支持。资源的下载地址一般会同时提供NI官方和百度网盘的地址。某些工具包NI地址失效或没有NI地址，只能使用百度网盘地址；如果百度网盘地址失效过期，可联系论坛客服更新。NI的服务器在美国，有时候速度很慢或下载容易出错，这样会造成安装时各种错误而无法安装。建议在下载完成后，对下载资源做校验和(NI一般会提供MD5或SHA256等)验证，与官方或视觉论坛提供的校验和对比，一致就可以安装；如不一致，则需要重新下载。视觉论坛早期下载上传的资源，基本上都是正常下载的资源；2019后下载的资源，都与NI的正确校验和对比过，保证是正确的资源才上传到百度网盘。校验和工具下载地址：文件Hash计算器FHash，文件校验和验证下载文件正确性验证，MD5值计算、SHA1值计算、SHA256值计算、CRC32值计算http://pcmv.cn/thread-26524-1-1.html

General Information

Installing this program may remove previous versions of IMAQVision for LabVIEW, IMAQ Vision for Measurement Studio, NI OCR, NI-IMAQ, andMeasurement & Automation Explorer (MAX) that are currently installed.

NI Vision 8.0 supports LabVIEW 7.0 or later, Visual Studio 6.0 orlater, and LabWindows™/CVI™ 7.0 or later. The installer specifically allowsside-by-side installations of NI Vision 8.0 for each of the supported versionsof LabVIEW, enabling you to use the NI Vision 8.0 Development Module withmultiple versions of LabVIEW. National Instruments recommends that you installLabVIEW, or any other supported development environment, before installing the NIVision 8.0 Development Module.

NOTE: The NI Vision8.0 Development Module overwrites existing NI-IMAQ examples, NI Visionexamples, and NI Vision VIs. Move modified examples or VIs that you want tosave to another directory before installing the NI Vision 8.0 DevelopmentModule.

For installation instructions and a complete list of systemrequirements, refer to the NI Vision 8.0 Development Module Release Notes.

New Features

All submodulesof the NI Vision 8.0 Development Module have the following new features:

Golden Template Comparison—Functions for comparing images to a golden template reference image.
Data Matrix Enhancements—In addition to enhancements regarding speed and accuracy, the Data Matrix functions now can output the ISO 16022 (AIM) grade for a given Data Matrix barcode.

Optical Character Verification—Functions for verifying the accuracy of characters within an image. For each character, the algorithm compares the character from the image with the reference character, and outputs a score based on the comparison.
Geometric Matching Enhancements—In addition to enhancements regarding speed and accuracy, Geometric Matching now supports searching for multiple templates within a single target image, and searching for templates within a calibrated image.
Shape Detection—Functions for searching for rectangles, lines, ellipses, and circles within an image.
Watershed Transform—computes the watershed transform on an image. Refer to the NI Vision Concepts Manual for more information about watershed transform.

Local Adaptive Threshold—Thresholds an image into a binary image based on the specified local adaptive thresholding method (e.g. Niblack, Background Correction).
JPEG2000 File I/O—Support for reading and writing JPEG2000 files.

VisionAssistant 8.0 has the following additions:

Run LabVIEW VI Step—Allows users to call custom LabVIEW VIs from within Vision Assistant scripts.
Japanese Language Support—Vision Assistant software and documentation are available in Japanese.

How to Activate the NI Vision 8.0 License

When you run an NI Vision 8.0 application for the first time, itprompts you to activate a license for the product. If you do not activate avalid license, the NI Vision 8.0 application will run in Evaluation Mode andcontinue to prompt you to activate a license on each subsequent launch.

Complete the following steps to activate the NI Vision 8.0 licensethrough an Internet connection.

Run the product you want to license.
Click Yes when prompted to interactively activate your product.
Ensure that Automatically activate through a secure Internet connection is selected, and click Next.
Enter the product serial number, and click Next.
Enter your registration information, and click Next.

TIP: Enter your email address to receive a copy ofyour activation code for your records.

Using NI Vision 8.0 with Microsoft VisualStudio .NET 2003

NI Vision 8.0 supports interoperability between the Vision 8.0ActiveX control and Microsoft Visual Studio .NET 2003. NI Vision installs thefollowing Interop Assemblies that allow .NET languages to correctly communicatewith the ActiveX controls:

· NationalInstruments.AxCWIMAQControlsLib.Interop.dll—cwimaq.ocx

· NationalInstruments.AxCWIMAQHelpButton.Interop.dll—CWIMAQHlpBtn.ocx

· NationalInstruments.AxCWMV.Interop.dll—cwmv.ocx

· NationalInstruments.AxNIOCRLib.Interop.dll—niocr.ocx

You can find these assemblies in the <Vision>dotNETAssembliesCurrent directory.The assemblies installed by NI Vision correctly wrap several methods thatgenerate errors if you call the methods using the assemblies generated byVisual Studio .NET. For information about the properties, methods, and eventsavailable with these assemblies, refer to the NI Vision for Visual BasicReference Help and the NI Vision for Visual Basic User Manual.

Creating a New .NET Application using NI Vision8.0

You must first add the NI Vision controls to your toolbox whencreating a new application. Complete the following steps to add the NI Visioncontrols to the Microsoft Visual Studio .NET 2003 Toolbox:

In Visual Studio .NET, either create a new application or open an existing one.
Open a form in Design View.
Select View»Toolbox.
Select the category in which you want the NI Vision controls to appear, such as General, Components, and so on.
Select Tools»Add/Remove Toolbox Items.
In the .NET Framework Components tab, select the controls you want to add to your application. Choose from CWIMAQ, CWIMAQVision, CWIMAQViewer, CWMachineVision, and NIOCR.

When the controls are in the toolbox, you can add them to yourforms by clicking the tool and drawing an area on the form. References to the NIVision Interop Assemblies are automatically added to your project.

Viewing the NI Vision 8.0 Examples

The NI Vision examples for Microsoft Visual Studio .NET 2003 areconverted from the NI Vision for Visual Basic examples. The .NET examples arewritten in Visual Basic .NET and demonstrate use of the NI Vision 8.0 InteropAssemblies. The examples are located in the <Vision>ExamplesMSVB.NET directory, and the images for the examples arelocated in the <Vision>ExamplesImages directory.

Converting an Existing Microsoft Visual Basic6.0 Application

Microsoft's automatic upgrade engine often generates its own Interopassemblies rather than referencing the official NI Vision 8.0 Interopassemblies. When this happens, your project will have two references for every NIVision assembly needed. Complete the following steps to correctly reference theNI Vision 8.0 Interop assemblies:

In Visual Studio .NET, select Edit»Find and Replace»Replace in Files.
Replace the following with NationalInstruments.CWIMAQControls:

- AxCWIMAQControlsLib

- AxCWIMAQHelpButtonLib

- AxCWMVLib

- AxNIOCRLib

Select View»Solution Explorer.
Expand the Project References.
Remove the following references if they are present:

- AxCWIMAQControlsLib

- AxCWIMAQHelpButton

- AxCWMV

- AxNIOCRLib

Known Issues

AVI functionality requires Microsoft DirectX 8.1 or later.
On Windows XP with Service Pack 2 installed, NI Vision 8.0 does not support reading AVI files located in the Local Settings folder, or any subfolders of this folder, when the AVI file uses any of the following compression filters:

- Indeo® Video 5.10 CompressionFilter

- Intel Indeo® Video R3.2

- Intel Indeo® Video 4.5

- Indeo® Video 5.10

Copying the AVI file to another folder resolvesthis problem.

Viewing the online help files requires Microsoft Internet Explorer 5 or later.
Using NI Vision 8.0 with LabWindows/CVI on a machine that does not support the MMX instruction set may cause an Illegal Operation exception to occur within the LabWindows/CVI environment. This error occurs when DirectX checks for the availability of the MMX instruction set on the machine.
The Visual Basic .NET examples may display the UI controls with incorrect size and location settings if you use a computer with a DPI display setting other than 96 DPI. 96 DPI is the default setting for most Windows operating systems.
NI Vision 8.0 does not support the use of Image Display control invoke nodes when using LabVIEW 7.0 Real-Time. The following examples use Image Display control Invoke nodes. Avoid downloading these examples to a LabVIEW 7.0 Real-Time target.
