在 MAC OS Sierra 上使用 Java 安装 OpenCV

Question

正在尝试在 MAC OS 10.12.2 (Sierra) 上为 Java 安装 OpenCV3.1。按照 link 中的命令进行操作。我想安装它以便我可以使用 OpenCV 配置 Eclipse。

安装时出现几个错误（尝试了不止一次）

尝试 1： brew install opencv3

错误代码段

[ 55%] 构建目标 opencv_imgcodecs make: *** [all] 错误 2

尝试 2： brew install opencv3 --HEAD --with-java

错误片段：

github 上针对问题给出的建议似乎没有解决问题。有人可以帮我解决这个问题吗？

我还尝试使用命令 brew install opencv 安装 openCV 2.4.13，这也引发了同样的错误。

Answer 1

终于可以安装了。问题是 Java 需要设置 ANT。虽然我安装了 ANT，但 ANT_HOME 在我的 ENV 中没有正确设置。正确设置后，我就能够解决此安装问题。

Answer 2

I would like to install this so that I can configure Eclipse with OpenCV.

为后代添加我如何让 opencv 在 Eclipse 中工作。我在 Eclipse 中的这一行出现错误，

import org.opencv.core.CvType;

因为我的构建 > 配置没有 opencv 外部 JAR 文件。所以我将我的 Java 项目转换为 Maven:

Right click project > Convert To Maven

然后按照以下步骤添加 Maven 依赖项： How do I add a Maven dependency in Eclipse?

最后我将粗体代码添加到 pom.xml

<project
...

<dependencies>
<!-- https://mvnrepository.com/artifact/org.bytedeco.javacpp-presets/opencv -->
<dependency>
    <groupId>org.bytedeco.javacpp-presets</groupId>
    <artifactId>opencv</artifactId>
    <version>4.0.1-1.4.4</version>
</dependency>
</dependencies>

<modelVersion 
...

然后右键单击项目 > 运行 As > Java Application ... 成功了！

试试这个示例 Java OpenCV 程序来检查你的程序是否有效：

import org.opencv.core.Core;
import org.opencv.core.CvType;
import org.opencv.core.Mat;

public class HelloCV {
        public static void main(String[] args){
                System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
                Mat mat = Mat.eye(3, 3, CvType.CV_8UC1);
                System.out.println("mat = " + mat.dump());
        }
}
