Question

我尝试使用Java记录oni文件。我录制一个文件时效果很好。但是当我想记录几个文件时，我遇到了问题。

以下是一些测试代码：

package test;

import org.OpenNI.Context;
import org.OpenNI.DepthGenerator;
import org.OpenNI.GeneralException;
import org.OpenNI.ImageGenerator;
import org.OpenNI.OutArg;
import org.OpenNI.RecordMedium;
import org.OpenNI.Recorder;
import org.OpenNI.ScriptNode;

public class RecorderProblems {

    private static final String SAMPLE_XML_FILE = "KinectConfig.xml";
    private static final String TEST1_ONI_FILE = "Test1.oni";
    private static final String TEST2_ONI_FILE = "Test2.oni";

    public static void main(String[] args) {
        Context context = null;
        DepthGenerator depthGenerator = null;
        ImageGenerator imageGenerator = null;
        try {
            OutArg<ScriptNode> scriptNode = new OutArg<ScriptNode>();

            // Init Hardware
            System.out.println("Init Hardware");
            context = Context.createFromXmlFile(SAMPLE_XML_FILE, scriptNode);
            depthGenerator = DepthGenerator.create(context);
            imageGenerator = ImageGenerator.create(context);
            context.startGeneratingAll();

            // Record 1
            System.out.println("Start Record 1");
            Recorder recorder = Recorder.create(context, "oni");
            // Adding next line produces a corrupt file, but the program runs fine
//          context.createProductionTree(recorder.getInfo());
            recorder.setDestination(RecordMedium.FILE, TEST1_ONI_FILE);
            recorder.addNodeToRecording(depthGenerator);
            recorder.addNodeToRecording(imageGenerator);
            for (int i = 0; i < 100; i++) {
                context.waitOneUpdateAll(imageGenerator);
                recorder.Record();
            }
            recorder.removeNodeToRecording(depthGenerator);
            recorder.removeNodeToRecording(imageGenerator);
            recorder.dispose();

            // Record 2
            System.out.println("Start Record 2");
            recorder = Recorder.create(context, "oni");
            // Adding next line produces a corrupt file, but the program runs fine
//          context.createProductionTree(recorder.getInfo());
            recorder.setDestination(RecordMedium.FILE, TEST2_ONI_FILE);
            recorder.addNodeToRecording(depthGenerator);
            recorder.addNodeToRecording(imageGenerator);
            for (int i = 0; i < 100; i++) {
                context.waitOneUpdateAll(imageGenerator);
                recorder.Record();
            }
            recorder.removeNodeToRecording(depthGenerator);
            recorder.removeNodeToRecording(imageGenerator);
            recorder.dispose();
        } catch (GeneralException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } finally {
            // End Hardware
            System.out.println("End Hardware");
            depthGenerator.dispose();
            depthGenerator = null;
            imageGenerator.dispose();
            imageGenerator = null;
            context.release();
            context.dispose();
        }
    }
}

当我尝试为第二条记录设置目标时，我得到一个StatusException“输入指针为空”。

如果我添加了未注释的行，程序运行正常，但创建的oni文件不可读。（我不确切知道这行是什么。）

我还尝试重新初始化上下文。起初这个工作正常，但是当我试图记录几个文件时，我也有重新初始化的问题。以下是一些示例代码：

package test;

import org.OpenNI.Context;
import org.OpenNI.DepthGenerator;
import org.OpenNI.GeneralException;
import org.OpenNI.ImageGenerator;
import org.OpenNI.OutArg;
import org.OpenNI.RecordMedium;
import org.OpenNI.Recorder;
import org.OpenNI.ScriptNode;

public class RecorderProblems {

    private static final String SAMPLE_XML_FILE = "KinectConfig.xml";

    public static void main(String[] args) {
        Context context = null;
        DepthGenerator depthGenerator = null;
        ImageGenerator imageGenerator = null;
        try {
            OutArg<ScriptNode> scriptNode = new OutArg<ScriptNode>();

            // Record 1
            for (int i = 0; i < 25; i++) {
                System.out.println("Run " + i);
                // Init Hardware
                System.out.println("Init Hardware " + i);
                context = Context
                        .createFromXmlFile(SAMPLE_XML_FILE, scriptNode);
                depthGenerator = DepthGenerator.create(context);
                imageGenerator = ImageGenerator.create(context);
                context.startGeneratingAll();

                System.out.println("Start Record " + i);
                Recorder recorder = Recorder.create(context, "oni");
                recorder.setDestination(RecordMedium.FILE, "test_" + i + ".oni");
                recorder.addNodeToRecording(depthGenerator);
                recorder.addNodeToRecording(imageGenerator);
                for (int j = 0; j < 100; j++) {
                    context.waitOneUpdateAll(imageGenerator);
                    recorder.Record();
                }
                recorder.removeNodeToRecording(depthGenerator);
                recorder.removeNodeToRecording(imageGenerator);
                recorder.dispose();

                System.out.println("End Hardware " + i);
                depthGenerator.dispose();
                depthGenerator = null;
                imageGenerator.dispose();
                imageGenerator = null;
                context.release();
                context.dispose();
            }

        } catch (GeneralException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

在第三次运行中，我得到一个StatusExcption“等待新数据时发生超时！”。

是否有人有录制文件的经验？我不知道，我是否使用了库错误，或者这是OpenNI的问题（使用Java）？

顺便说一下，我使用的是OpenNI 1.5.2.23和Kinect摄像头。 XML配置文件“KinectConfig.xml”是随OpenNI示例一起提供的默认XML文件。我刚刚重命名了。

感谢您的帮助

Answer 1

你为什么这么复杂？您可以使用Android libraries 。

Answer 2

我有读取VGA分辨率深度和rgb投注相同超时错误的问题。如果我将任一深度或rgb的分辨率降低到四分之一vga一切正常。
