HI @1210586191 ,
Did you follow below suggestion in deepstream_lpr_app/deepstream-lpr-app at master · NVIDIA-AI-IOT/deepstream_lpr_app · GitHub ?

For Chinese plate recognition, please make sure the Chinese language support is in the OS.
For example:
With Ubuntu

  1. Install Chinese Language package .
    sudo apt-get install language-pack-zh-hans
  2. Set the Chinese language enviroment
    export LANG=zh_CN.UTF-8
    export LANGUAGE=“zh_CN:zh:en_US:en”

Yes，I follow the suggestion

I realize that this problem may be caused by the Ubuntu system not installing Chinese fonts.
Then， I run this command

apt-get install ttf-wqy-microhei

to get the font package and install it.
The problem is solved！
thanks very much!
