我正在开发OCR系统,需要捕获图像并进行OCR,我想捕获部分文件(确切意图文本在哪里)或裁剪捕获的图像,然后再将其传递给OCR处理以获得更好的效果。
我试过下面的代码,但是我不能把它作为我试图存档的东西,因为我是android java的初学者
private void startCameraActivity() {
try {
String IMGS_PATH = Environment.getExternalStorageDirectory().toString() + "/ocr/imgs";
prepareDirectory(IMGS_PATH);
String img_path = IMGS_PATH + "/ocr.jpg";
outputFileUri = Uri.fromFile(new File(img_path));
final Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
takePictureIntent.putExtra("crop", "true");
takePictureIntent.putExtra("scale", true);
takePictureIntent.putExtra("aspectX", 1);
takePictureIntent.putExtra("aspectY", 1);
takePictureIntent.putExtra("outputX", 150);
takePictureIntent.putExtra("outputY", 100);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(takePictureIntent, PHOTO_REQUEST_CODE);
}
} catch (Exception e) {
Log.e(TAG, e.getMessage());
}
}
@Override
public void onActivityResult(int requestCode, int resultCode,
Intent data) {
//making photo
if (requestCode == PHOTO_REQUEST_CODE && resultCode == Activity.RESULT_OK) {
doOCR();
} else {
Toast.makeText(this, "ERROR: Image was not obtained.", Toast.LENGTH_SHORT).show();
}
}
private void doOCR() {
prepareTesseract();
startOCR(outputFileUri);
}
有人帮助我,谢谢。
注意
takePictureIntent.putExtra("crop", "true");
takePictureIntent.putExtra("scale", true);
takePictureIntent.putExtra("aspectX", 1);
takePictureIntent.putExtra("aspectY", 1);
takePictureIntent.putExtra("outputX", 150);
takePictureIntent.putExtra("outputY", 100);
清除我的缓存后,我注意到上面的代码正在打开完整操作应用程序,可以裁剪图片,现在一切正常。
感谢。
