安装 easypr 和 opencv 库在树莓派上可以通过以下步骤进行:
1. 更新软件源列表:
```
sudo apt-get update
```
2. 安装 opencv 库:
```
sudo apt-get install libopencv-dev python-opencv
```
3. 安装 easypr 库:
```
git clone https://github.com/liuruoze/EasyPR.git
cd EasyPR
mkdir build
cd build
cmake ..
make
sudo make install
```
4. 测试 easypr 库:
```
cd ../bin
./easypr test.jpg
```
如果一切正常,你应该能够看到 easypr 成功识别出图像中的车牌号码。
注意:这些安装步骤需要一定的时间和空间,尤其是编译和安装 opencv 库和 easypr 库,可能需要花费几个小时的时间。另外,如果你的树莓派硬件配置较低,可能会影响编译和运行的速度。
