I'm developing and android app that take a picture and OCRed it.
I'm getting this error sometime and sometime not without changing my code,
THE ERROR : 01-08 20:41:59.940: A/libc(10967): Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1)
I have a method that crop the image to let the user highlight the text :
private void performCrop(){ File file = new File(_path); Uri outputFileUri = Uri.fromFile(file); try{ //call the standard crop action intent (the user device may not support it) Intent cropIntent = new Intent("com.android.camera.action.CROP"); cropIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri); //indicate image type and Uri cropIntent.setDataAndType(picUri, "image/*"); //set crop properties cropIntent.putExtra("crop", "true"); //indicate aspect of desired crop cropIntent.putExtra("aspectX", 5); cropIntent.putExtra("aspectY", 1); //indicate output X and Y cropIntent.putExtra("outputX", 500); cropIntent.putExtra("outputY", 100); //retrieve data on return cropIntent.putExtra("return-data", true); //start the activity - we handle returning in onActivityResult startActivityForResult(cropIntent, 2); }catch(ActivityNotFoundException anfe){ //display an error message String errorMessage = "Whoops - your device doesn't support the crop action!"; Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT); toast.show(); } catch (Exception ex) { Log.v(TAG, ex.toString()); } } and here is the method that do the OCR :
protected void onPhotoTaken() { _taken = true; BitmapFactory.Options options = new BitmapFactory.Options(); options.inSampleSize = 2; Bitmap bitmap = BitmapFactory.decodeFile(_path, options); try { ExifInterface exif = new ExifInterface(_path); int exifOrientation = exif.getAttributeInt( ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL); Log.v(TAG, "Orient: " + exifOrientation); int rotate = 0; switch (exifOrientation) { case ExifInterface.ORIENTATION_ROTATE_90: rotate = 90; break; case ExifInterface.ORIENTATION_ROTATE_180: rotate = 180; break; case ExifInterface.ORIENTATION_ROTATE_270: rotate = 270; break; } Log.v(TAG, "Rotation: " + rotate); if (rotate != 0) { // Getting width & height of the given image. int w = bitmap.getWidth(); int h = bitmap.getHeight(); // Setting pre rotate Matrix mtx = new Matrix(); mtx.preRotate(rotate); // Rotating Bitmap bitmap = Bitmap.createBitmap(bitmap, 0, 0, w, h, mtx, false); } // Convert to ARGB_8888, required by tess bitmap = bitmap.copy(Bitmap.Config.ARGB_8888, true); } catch (IOException e) { Log.e(TAG, "Couldn't correct orientation: " + e.toString()); } // _image.setImageBitmap( bitmap ); Log.v(TAG, "Before baseApi"); TessBaseAPI baseApi = new TessBaseAPI(); baseApi.setDebug(true); baseApi.init(DATA_PATH, lang); baseApi.setImage(bitmap); String recognizedText = baseApi.getUTF8Text(); baseApi.end(); // You now have the text in recognizedText var, you can do anything with it. // We will display a stripped out trimmed alpha-numeric version of it (if lang is eng) // so that garbage doesn't make it to the display. Log.v(TAG, "OCRED TEXT: " + recognizedText); if ( lang.equalsIgnoreCase("eng") ) { recognizedText = recognizedText.replaceAll("[^a-zA-Z0-9]+", " "); } recognizedText = recognizedText.trim(); if ( recognizedText.length() != 0 ) { _field.setText(_field.getText().toString().length() == 0 ? recognizedText : _field.getText() + " " + recognizedText); _field.setSelection(_field.getText().toString().length()); } // Cycle done. }
