Question

我使用openCV 3.4.3，我想在Java中使用以下脚本，您可以在此处查看源代码：https://docs.opencv.org/3.4/d3/db7/tutorial_hdr_imaging.html并选择Java。

onCreate之前有我的代码：

public List<Mat> images = new ArrayList<>();
public List<Float> times = new ArrayList<>();

设置图片：

String pathNameFile = "file://"+Environment.getExternalStorageDirectory()+"/test_"+date+"_"+pictureNumber+".jpg";
file = new File(pathNameFile);
Mat img = Imgcodecs.imread(pathNameFile);
images.add(img);

和时间：

lastExifExposureTime = result.get(CaptureResult.SENSOR_EXPOSURE_TIME);
double val = (double)lastExifExposureTime / 1000000000.0;
float floatValue = (float) val;
times.add(floatValue);

这是我进行融合的代码：

    Mat response = new Mat();
    CalibrateDebevec calibrate = Photo.createCalibrateDebevec();
    Mat matTimes = new Mat(times.size(), 1, CvType.CV_32F);
    float[] arrayTimes = new float[(int) (matTimes.total()*matTimes.channels())];
    for (int i = 0; i < times.size(); i++) {
        arrayTimes[i] = times.get(i);
    }
    matTimes.put(0, 0, arrayTimes);
    calibrate.process(images, response, matTimes);
    Mat hdr = new Mat();
    MergeDebevec mergeDebevec = Photo.createMergeDebevec();
    mergeDebevec.process(images, hdr, matTimes);
    Mat ldr = new Mat();
    TonemapDurand tonemap = Photo.createTonemapDurand(2.2f, 4.0f, 1.0f, 2.0f, 2.0f);
    tonemap.process(hdr, ldr);
    Mat fusion = new Mat();
    MergeMertens mergeMertens = Photo.createMergeMertens();
    mergeMertens.process(images, fusion);
    Core.multiply(fusion, new Scalar(255,255,255), fusion);
    Core.multiply(ldr, new Scalar(255,255,255), ldr);
    Imgcodecs.imwrite("fusion.png", fusion);
    Imgcodecs.imwrite("ldr.png", ldr);
    Imgcodecs.imwrite("hdr.hdr", hdr);
    System.exit(0);

我不使用loadExposure方法，因为我在拍照时会输入时间和图片值。

有我的错误：

我该怎么做才能解决此问题？

谢谢

OpenCV功能图片不起作用-为什么这样做？
