“Emgu.CV.CvInvoke”的类型初始值设定项引发异常。

Posted 2023-03-14

RT，跪求解决方法

参考技术A 首先确定没有重复安装opencv和emgucv两种，这样有可能在配置path时会出错。emgucv是包含opencv的，使用C#开发的朋友们，可以放心的只安装emgucv。

1、如遇错误提示：tbb_debug.dll找不到
请下载安装Intel TBB库，需要将tbb库或dll文件所在路径，配置带系统环境变量path中。

2、如遇错误提示：“Emgu.CV.CvInvoke”的类型初始值设定项引发异常
（1）、注销或重启计算机，使得系统环境变量中的path生效；
（2）、通过path中设置的路径去寻找对应的dll文件，查看是否存在，是否被成功引用到VS中；
（3）、copy dll文件到debug和release目录中。
（4）、尝试将.Net FrameWork版本降低，如果是4.0的就降低到3.5，如果是3.5的就降低到2.0。

官方解决办法：
（1）安装时注意：
ou can run an AutoIt script that automates much of the process, including installing OpenCV if necessary, and lets you start developing with Visual Studio right away.
Getting the Dependency
Emgu CV
use WCF(Windows Communication Foundation) therefore requires .Net 3.0
For version 2.4+ the bundled OpenCV binary is build with Visual Studio 2010, you will needs to installed
MSVCRT 9.0 SP1 x86
or
MSVCRT 9.0 SP1 x64to resolve the dependency issue.
For Version 2.0+, the bundled OpenCV binary is build with Visual Studio 2008, you will needs to installed
MSVCRT 9.0 SP1
to resolve the dependency issue.
For Version 1.5, the bundled OpenCV pre1.1 binary is build with Visual Studio 2005, you will needs to installed
MSVCRT 8.0 SP1
to resolve the dependency issue.
Building the Examples
Follow
this link
to the file server on Source Forge.
Download and extract the windows installer.
Install the software
Go to the Solution folder
If you are using Visual Studio 2008, browse to VS2008
If you are using Visual Studio 2010, browse to VS2010
Open
Emgu.CV.Example.sln
and build the solution. At this point, you should be able to run the example programs.
Creating a New Project in Visual Studio
To use the framework in Visual Studio, you need to
Download and extract the binary files package
Emgu.CV.Windows.Binary-version.zip
For a Full guide to using the dependencies under Visual Studio and C# see the C# Tutorial.
Core Functionality
Managed Code
Create a new Visual Studio project or use an existing one
Add the two files
Emgu.Utils.dll
and
Emgu.CV.dll
to
References
of the project. as well.
Optionally put the following lines in the top of your code to include the Emgu.CV namespace.

using Emgu.CV; using Emgu.CV.Structure;

Open CV unmanaged dll
Copy the OpenCV dll files: opencv_calib3dXXX.dll, opencv_contribXXX.dll, opencv_coreXXX.dll, opencv_features2dXXX.dll, opencv_ffmpegXXX.dll,opencv_flannXXX.dll, opencv_gpuXXX.dll, opencv_highguiXXX.dll, opencv_imgprocXXX.dll, opencv_legacyXXX.dll, opencv_mlXXX.dll,opencv_objdetectXXX.dll, opencv_videoXXX.dll and cvextern.dll to the execution directory, where XXX is the OpenCV version number.
（2）The type initializer for 'Emgu.CV.CvInvoke' threw an exception.（Emgu.CV.CvInvoke 的类型初始值设定项引发异常）
If you see this exception, please check the following
Have you installed MSVCRT?
For Version 2.4+, the bundled OpenCV binary is build with Visual Studio 2010, you will needs to installed
MSVCRT 10.0 SP1 x86
or
MSVCRT 10.0 SP1 x64
to resolve the dependency issue.
For Version 2.0+, the bundled OpenCV binary is build with Visual Studio 2008, you will needs to installed
MSVCRT 9.0 SP1
to resolve the dependency issue.
For Version 1.5, the bundled OpenCV pre1.1 binary is build with Visual Studio 2005, you will needs to installed
MSVCRT 8.0 SP1
to resolve the dependency issue.
Have you copied the OpenCV dlls to the execution directory?
Make sure the unmanaged DLLs are in the execution directory.
For Emgu CV version <= 2.1, this means the following dlls:cvXXX.dll, cvauxXXX.dll, cxcoreXXX.dll, highguiXXX.dll, opencv_ffmpegXXX.dll, mlXXX.dllcvextern.dll
where
XXX
is the OpenCV version number.
For Emgu CV version 2.2, 2.3 this means the following dlls:
opencv_calib3dXXX.dll, opencv_contribXXX.dll, opencv_coreXXX.dll, opencv_features2dXXX.dll, opencv_highguiXXX.dll, opencv_imgprocXXX.dll, opencv_legacyXXX.dll, opencv_mlXXX.dll, opencv_objectdetectXXX.dll, opencv_videoXXX.dll
where
XXX
is the OpenCV version number.
For EMGU CV version >=2.4
cudart64_42_9.dll, cvextern.dll, npp64_42_9.dll, opencv_calib3dXXX.dll, opencv_contribXXX.dll, opencv_coreXXX.dll, opencv_features2dXXX.dll, opencv_flannXXX.dll, opencv_highguiXXX.dll, opencv_imgprocXXX.dll, opencv_legacyXXX.dll, opencv_mlXXX.dll, opencv_nonfreXXX.dll, opencv_objectdetectXXX.dll, opencv_videoXXX.dll,
where
XXX
is the OpenCV version number.
The best way to set up your project is:
Copy the unmanaged DLLs to your project folder
Right click on the project, click Add->Existing Item and select all unmanaged DLLs. Add them to the project.
For each of the included Dlls, left click on it, find the "Copy to Output Directory" option and select "Copy if newer"

Emgu.CV.CvInvoke的类型初始值设定项引发异常

被这个问题蛋疼了一个下午，终于解决了。
我的服务器出现这个问题的原因：可能是没有安装emgucv。

解决方法：

1.下载并安装emgucv

下载地址：链接: https://pan.baidu.com/s/1slyWCgP 密码: kbc5

2.服务器添加环境变量

添加变量值：C:\Emgu\emgucv-windows-universal 3.0.0.2157\bin

我的安装默认装在c盘，最要是bin目录

3.bin 目录里面有 86和64的文件夹，复制两个文件夹到你的程序的根目录，替换原来的即可。
