opencv - UnsatisfiedLinkError使用opencv进行处理

Question

我在打电话:

Mat opencv_K= new Mat(3, 3, CvType.CV_32F);

在 Processing 中素描，我收到以下错误:

java.lang.UnsatisfiedLinkError: org.opencv.core.Mat.n_Mat(III)J
    at processing.opengl.PSurfaceJOGL$2.run(PSurfaceJOGL.java:480)
    at java.lang.Thread.run(Thread.java:745)
UnsatisfiedLinkError: org.opencv.core.Mat.n_Mat(III)J
A library relies on native code that's not available.
Or only works properly when the sketch is run as a 32-bit application.

这个错误在我看来与报告的错误不同 here .

一个最小的例子是:

import processing.core.PVector;
import org.opencv.core.Mat;
import org.opencv.core.CvType; 
import org.opencv.core.Core;
Mat opencv_K= new Mat(3, 3, CvType.CV_32F); 

而且这种情况下的错误有点类似:

UnsatisfiedLinkError: org.opencv.core.Mat.n_Mat(III)J
A library relies on native code that's not available.
Or only works properly when the sketch is run as a 32-bit application.

我在 Ubuntu 平台上使用 Processing 3。

解决方案:

只需在相关代码前添加System.loadLibrary(Core.NATIVE_LIBRARY_NAME);即可
