This article mainly introduces the relevant knowledge of Java's opencv development method, the content is detailed and easy to understand, the operation is simple and fast, and has a certain reference value, I believe you will gain something after reading this Java opencv development method article, let's take a look at it.

1. Download and install OpenCV

Select the appropriate platform installation package to download, and then double-click the installation, that is, the process of decompression. Here we mainly record the environment building and opencv-342 version under windows.

two。 Find the jar package

1) in... You can find opencv-xx.jar under the opencvuildjava path.

2) idea new project. Add jars or derectories to Project Structure-> modules-> dependencies. Select 1) jar package.

3) run the program

System.loadLibrary (Core.NATIVE_LIBRARY_NAME); Mat mat = Mat.eye (4,4, CvType.CV_8UC1); System.out.println ("mat =" + mat.dump ())

A miracle happened:

Java.lang.UnsatisfiedLinkError: no opencv_java342 in java.library.path

4) then supplement the operation:

Add to run configurations vm options

-Djava.library.path=E:programfileopencvuildjavax64

The path to opencv-342.dll
