我已经使用 tesseract 库开发了 OCR 应用程序,
应用程序在执行以下代码期间退出:
/*...
... Other Code stuff
...*/
protected Boolean doInBackground(String... arg0) {
/*...
... Other Code stuff
...*/
Pix pix = getPixFromBitmap(bitmap);
pix = preprocess(pix);
Pixa pixa = slice(pix); // Code Updated
try {
baseApi.setPageSegMode(TessBaseAPI.PSM_SINGLE_LINE);
int num = pixa.size();
for (int i = 0; i < num; i++) {
Pix pixi = pixa.getPix(i);
/*...
... Other Code stuff
...*/
}
pixa.recycle();
baseApi.end();
} catch (RuntimeException e) {
Log.e("OcrRecognizeAsyncTask","Caught RuntimeException in request to Tesseract. Setting state to CONTINUOUS_STOPPED.");
e.printStackTrace();
try {
// baseApi.clear();
activity.stopHandler();
} catch (NullPointerException e1) {
// Continue
}
return false;
}
private Pixa slice(Pix pix) {
HydrogenTextDetector htd = new HydrogenTextDetector();
HydrogenTextDetector.Parameters hydrogenParams = htd.getParameters();
hydrogenParams.debug = false;
hydrogenParams.skew_enabled = true;
htd.setParameters(hydrogenParams);
htd.setSourceImage(pix);
pix.recycle();
htd.detectText();
Pixa unsorted = htd.getTextAreas();
Pixa pixa = unsorted.sort(Constants.L_SORT_BY_X, Constants.L_SORT_DECREASING);
unsorted.recycle();
htd.clear();
return pixa;
}
Logcat详细信息如下:
02-23 13:37:09.986: I/WindowManager(102): Setting rotation to 0, animFlags=1

我将位图转换为 Leptonica Pix 对象,而不是将 Pix 转换为 Leptonica Pixa 对象,而不是进行 OCR 重组。
在处理过程中,有时 OCR 重组成功完成,有时 android 主屏幕自动出现。
我不知道这背后的问题是什么,为什么会出现RemoteException警告?
请帮我解决这个问题。
谢谢,
