我是tess-two庫的新手。我可以添加從繪製其甚至將這個庫和獲取圖像,但我下面讓錯誤的文字:OCR文本識別錯誤文本顯示
這裏是我的完整代碼:
Bitmap image;
private TessBaseAPI mTess;
String datapath = "";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//init image
image = BitmapFactory.decodeResource(getResources(), R.drawable.test_image);
//initialize Tesseract API
String language = "eng";
datapath = getFilesDir()+ "/tesseract/";
mTess = new TessBaseAPI();
checkFile(new File(datapath + "tessdata/"));
mTess.init(datapath, language);
}
private void checkFile(File file) {
if (!file.exists()&& file.mkdirs()){
copyFiles();
}
if(file.exists()) {
String datafilepath = datapath+ "/tessdata/eng.traineddata";
File datafile = new File(datafilepath);
if (!datafile.exists()) {
copyFiles();
}
}
}
public void processImage(View view){
String OCRresult = null;
mTess.setImage(image);
OCRresult = mTess.getUTF8Text();
TextView OCRTextView = (TextView) findViewById(R.id.OCRTextView);
OCRTextView.setText(OCRresult);
}
private void copyFiles() {
try {
String filepath = datapath + "/tessdata/eng.traineddata";
AssetManager assetManager = getAssets();
InputStream instream = assetManager.open("tessdata/eng.traineddata");
OutputStream outstream = new FileOutputStream(filepath);
byte[] buffer = new byte[1024];
int read;
while ((read = instream.read(buffer)) != -1) {
outstream.write(buffer, 0, read);
}
outstream.flush();
outstream.close();
instream.close();
File file = new File(filepath);
if (!file.exists()) {
throw new FileNotFoundException();
}
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
我獲取文本,如:
mmmm.and,MMM,1111等
任何幫助表示讚賞。
