tr：免费离线OCR离线的中文文本检测+识别SDK

# tr - Text Recognition 一款针对扫描文档的离线文本识别SDK，核心代码全部采用C++开发，并提供Python接口 #### 更新说明 + c++接口支持 + 支持Windows系统 + 添加python2支持 + 去除opencv-python、Pillow依赖，降低部署难度 + 支持多线程 + 支持GPU #### Contact Email: [email protected] #### Requirements + Windows 7+/Ubuntu 16.04/Ubuntu 18.04 + python2/python3，需要安装numpy + Windows系统需要安装[VC_redist.x64.exe](https://download.visualstudio.microsoft.com/download/pr/89a3b9df-4a09-492e-8474-8f92c115c51d/B1A32C71A6B7D5978904FB223763263EA5A7EB23B2C44A0D60E90D234AD99178/VC_redist.x64.exe ) #### GPU版本安装说明 如果对速度有要求，推荐安装GPU版本<br> 要使用GPU版本，复制tr_gpu文件夹里面的文件到tr文件夹<br> 注意: 需要先安装CUDA 10.1以及cuDNN 7.6.5<br> <br> 若不想安装CUDA/cuDNN，可以使用docker部署 <pre>docker pull mcr.microsoft.com/azureml/onnxruntime:v1.3.0-cuda10.1-cudnn7 sudo nvidia-docker run -v /path/to/tr:/path/to/tr --rm -it mcr.microsoft.com/azureml/onnxruntime:v1.3.0-cuda10.1-cudnn7 </pre> #### Install + 安装方法一 <pre>git clone https://github.com/myhub/tr.git cd ./tr sudo python setup.py install </pre> + 安装方法二 <pre>sudo pip install git+https://github.com/myhub/tr.git@master </pre> #### Test <pre> python2 demo.py # python2兼容测试 python3 test.py # 可视化测试 python3 test-multi-thread.py # 多线程测试 </pre> #### 关联项目 + 若需要Web端调用，推荐参考<a href="https://github.com/alisen39/TrWebOCR">TrWebOCR</a> #### Python Example <pre>import tr # detect text lines, return list of (cx, cy, width, height, angle) print(tr.detect("imgs/web.png", tr.FLAG_RECT)) # detect text lines with angle, return list of (cx, cy, width, height, angle) print(tr.detect("imgs/id_card.jpeg", tr.FLAG_ROTATED_RECT)) # recognize text line, return (text, confidence) print(tr.recognize("imgs/line.png")) # detect and recognize text lines with angle, return list of ((cx, cy, width, height, angle), text, confidence) print(tr.run("imgs/id_card.jpeg")) </pre> #### C++ Example <pre>tr_init(0, 0, "crnn.bin", NULL); #define MAX_WIDTH 512 int unicode[MAX_WIDTH]; float prob[MAX_WIDTH]; auto ws = tr_recognize(0, (void *)"line.png", 0, 0, 0, unicode, prob, MAX_WIDTH); tr_release(0); </pre> #### 效果展示 <img src="https://gitee.com/microic/tr/raw/master/imgs/output/id_card/1.png" /> <img src="https://gitee.com/microic/tr/raw/master/imgs/output/id_card/2.png" /> <hr> <img src="https://gitee.com/microic/tr/raw/master/imgs/output/name_card/1.png" /> <img src="https://gitee.com/microic/tr/raw/master/imgs/output/name_card/2.png" />
