opencv - 错误:找不到符号CV_32FC3

Question

我正在使用HIPI进行一些图像处理!
有一次，当我定义opencv Mat时，在代码中使用了变量CV_32FC3。

Mat mat = new Mat(rows, cols, CV_32FC3); 

不幸的是，我收到一条错误消息，指出未找到该符号!

附:

我使用集成到HIPI的bytedeco来进行图像处理

在HIPI的build.gradle文件中，我有:

compile group: 'org.bytedeco', name: 'javacv-platform', version: '1.3.2'
compile group: 'org.bytedeco.javacpp-presets', name: 'opencv', version: '3.2.0-1.3 '
compile group: 'org.bytedeco.javacpp-presets', name: 'opencv', version: '3.2.0-1.3 ', classifier: 'macosx-x86_64'
compile group: 'org.bytedeco.javacpp-presets', name: 'opencv', version: '3.2.0-1.3 ', classifier: 'linux-x86_64'
compile group: 'org.bytedeco.javacpp-presets', name: 'opencv', version: '3.2.0-1.3 ', classifier: 'windows-x86_64'

在我的代码中，我导入了opencv_core:

import org.bytedeco.javacpp.opencv_core.*;
import org.bytedeco.javacpp.helper.opencv_core.*;
import org.bytedeco.javacpp.presets.opencv_core.*;

谁能告诉我怎么了？还是我忘记了什么？

我得到的错误stacktrace是:

根据代码，您似乎正在使用Java(但是尚未明确定义)。因此，在Java中，Mat的类型存储在CvType类下，因此您需要将矩阵创建为:

Mat mat = new Mat(rows, cols, CvType.CV_32FC3);
