我正在尝试将 Tesseract 实现到我的 android 项目中,但是在尝试完成 OCR 时遇到了崩溃。
以下是我设置 Tesseract 的方式:
TessBaseAPI baseApi = new TessBaseAPI();
baseApi.setDebug(true);
baseApi.init(imagePath, "eng");
baseApi.setImage(bitmap);
String recognizedText = baseApi.getUTF8Text();
baseApi.end();
这就是我设置图像信息以传递到 TesseractAPI 的方式:
destination = new File(Environment.getExternalStorageDirectory(), name + ".png");
imagePath = destination.getAbsolutePath();
String name = dateToString(new Date(),"yyyy-MM-dd-hh-mm-ss");
这是Logcat:
