我想從Android中捕獲的任何圖像中提取文本。所以我創建了一個訪問相機的意圖，並用startActivityForResult開始。tesseract數據路徑不存在
這是我的onActivityResult代碼：
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
String state = Environment.getExternalStorageState();
if (Environment.MEDIA_MOUNTED.equals(state)) {
Bundle extras = data.getExtras();
Bitmap bitmap = (Bitmap) extras.get("data");
TextView res = (TextView) findViewById(R.id.hello);
//imageView.setImageBitmap(imageBitmap);
//Image image = ImageIO.read(imageFile);
//BufferedImage buffimg = (BufferedImage) image;
//BufferedImage img = ImageHelper.convertImageToGrayscale(buffimg);
//ITesseract instance = new Tesseract(); // JNA Interface Mapping
//ITesseract instance = new Tesseract1(); // JNA Direct Mapping
//TessDataManager.initTessTrainedData(context);
if(isStoragePermissionGranted() == true) {
TessBaseAPI tessBaseAPI = new TessBaseAPI();
String path = Environment.getExternalStorageDirectory() + "/";
//String path = "/mnt/sdcard/";
tessBaseAPI.setDebug(true);
tessBaseAPI.init(path, "eng");
tessBaseAPI.setImage(bitmap);
String text = tessBaseAPI.getUTF8Text();
tessBaseAPI.end();
res.setText(text);
}
}
else
{
TextView res = (TextView) findViewById(R.id.hello);
res.setText("Well damn");
}
}
}
public boolean isStoragePermissionGranted() {
if (Build.VERSION.SDK_INT >= 23) {
if (checkSelfPermission(android.Manifest.permission.READ_EXTERNAL_STORAGE)
== PackageManager.PERMISSION_GRANTED) {
Log.v(TAG,"Permission is granted");
return true;
} else {
Log.v(TAG,"Permission is revoked");
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, 1);
return false;
}
}
else { //permission is automatically granted on sdk<23 upon installation
Log.v(TAG, "Permission is granted");
return true;
}
}
，我收到的錯誤是：
java.lang.RuntimeException: Unable to resume activity {com.example.abc.snaptravel/com.example.abc.snaptravel.MainActivity}: java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=1, result=-1, data=Intent { act=inline-data dat=content: (has extras) }} to activity {com.example.abc.snaptravel/com.example.abc.snaptravel.MainActivity}: java.lang.IllegalArgumentException: Data path does not exist!
具體做法是：
Data path does not exist
我有看了很多關於這個問題，嘗試了許多不同的解我在路徑名中也嘗試過使用和不使用"/tessdata/"。
如果您有任何建議，我會非常感激他們。謝謝！
