如果对速度有要求,推荐安装GPU版本
要使用GPU版本,复制tr_gpu文件夹里面的文件到tr文件夹
注意: 需要先安装CUDA 10.1以及cuDNN 7.6.5
若不想安装CUDA/cuDNN,可以使用docker部署
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
git clone https://github.com/myhub/tr.git cd ./tr sudo python setup.py install
sudo pip install git+https://github.com/myhub/tr.git@master
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
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"))
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);
