tesseract-ocr-scanner's Introduction

Tesseract-OCR-Scanner

Tesseract-OCR-Scanner是基于Tesseract-OCR实现的数字自动识别。

实现效果图

实现说明

具体参考博客：http://blog.csdn.net/qq_17766199/article/details/77963278

其他

支持androidx。旧版在1.0分支。
训练数据放在res/raw目录下，需要识别其他语言可另行下载替换。本项目使用的为英文识别训练包。
数字识别时，框小一点会好识别。（可以手动调节大小的扫描框）
数字识别对于手写体识别效率不高，主要是训练包问题。有需求可自行训练。

识别纯数字用哪个训练数据最好

项目导入运行无法实现识别功能

楼主，你好！我把这个项目导入到Android Studio运行后，无法实现自动扫描和拍照识别功能，相机拍摄手机号码时会先聚焦然后图像变模糊，一直这样来回跳动。

关于自动识别

你好，因为自动识别的准确率不是太高，我想关闭自动扫描识别，只保留拍照识别功能，请问一下在哪里可以关闭？

尝试修改正则，识别短串数字时结果有问题

尝试用这个项目来识别短串数字，比如2-3位的数字“12”或者"123"，所以修改匹配的正则代码，改成

 private static Pattern pattern = Pattern.compile("\\d{3}$*");

结果app的识别就很不稳定了，摄像头对着没有数字的空白区域，也总是跳出来一堆很乱的结果，比如下面这样：

保持正则同样的写法，只是增加待识别数字的长度(\d{3}改成\d{10})，识别的结果还是很准确

 private static Pattern pattern = Pattern.compile("\\d{10}$*");

所有现在有点迷惑，针对这种现象，请教博主有没有大致的思路，能推断出问题出在哪里吗？是项目其他部分的bug，还是算法和模型本身就有这个限制呢？
