Run the opencv-based program on another machine-instance

ArticleThe solution is as follows:

Scenario 1:Will be able to run on your computer based on opencvEngineeringCopy the file to someone else's (mainly a teacher) computer, avoiding the need for other people to configure library files, directory files, and Lib.

Scenario 2:Will be able to run on your computer based on opencvProgram(Exe)Copy to a computer without a CV library for demonstration.

1. First, let's take a look at your specific configuration process: the configuration principle can be found in the previous blogHttp://blog.csdn.net/lanbing510/article/details/8806602.

1. Copy the include folder under the \ opencv \ build directory and the bin and Lib folders under \ opencv \ build \ x86 \ VC10 to the directory where the project is located (and C ++ project or stdafx. h ).

2. Add a directory. In order to implement scenario 1, you need to use a relative path. First, use the relative path to perform the popular science program,'.\'Represents the current directory,'..\'Indicates the parent directory. Note:'\'It is a VC reserved word, so you need to use '\' instead of '\' when writing a program. Use '/' for the network path '/'. The specific configuration is as follows:

The link configuration is as usual. You only need to add these commonly used Lib:

Opencv_nonfree243d.lib
Opencv_legacy243d.lib
Opencv_imgproc243d.lib
Opencv_core243d.lib
Opencv_highgui243d.lib
Opencv_video243d.lib
Opencv_ml243d.lib
Opencv_features2d243d.lib

2. After compilation, put the corresponding DLL file in the directory where the EXE is located. However, if there are too many DLL files, it looks very bloated and you want to put different folders in the DLL file set, then let the program be selected when running the program. One way is to set the environment variable, but the problem arises.The instructor asks you to configure the environment variables on the spot. If the other party does not have the corresponding library, let alone the corresponding environment variable settings.

The solution is to make the following configuration (the premise is that the bin of the DLL folder has been copied to the project directory in step 1 ):

That is, set path in the Environment option, so that you can also use the DLL in Multiple folders. Concise and clear.

3. Compile and run the above configurations.

2. Make a simple prompt on Case 2.

If the recipient does not needSource codeAnd project, only used for display, you can directly copy the bin folder to the directory where the EXE file is located (vs generally asks the debug or release folder), but you will find that, double-click EXE and you will not be able to run normally. Instead, you will be prompted that you cannot find the DLL, as mentioned above, it is impossible for you to run the program without configuring environment variables or placing the DLL file in the directory at the same level as the exe. However, to do a demonstration, it cannot be too ugly. an EXE attachment contains various DLL files, there are two ways to do this:

1. Use the batch processing method, that is, to write a bat, setpath first, and then run your EXE, but it is still not beautiful. When you run a BAT file instead of EXE for everyone to see.

2. For details, refer to method 2. You can write a shell and use ShellExecuteCall exe. Very easy, very short command.

Paste the shell program I wrote below

 

# Include <windows. h> # include <iostream> using namespace STD; # define exename _ T ("motion_ds.exe") # define dllpath _ T (". \ bin ") int _ tmain (INT argc, _ tchar * argv []) {try {ShellExecute (null, null, exename, null, dllpath, sw_show );} catch (...) {STD: cout <"exception occurred. Check the source program" <exename <STD: Endl;} return 0 ;}
 

Put shell.exe behind the compilation and operationMotion_ds.EXEDirectory, SetMotion_ds.Put exein the binfolder. During demonstration, you only need to double-click shell.exe.
