# 拍照流程
1 执行  capture.py
2 执行完成后 \ssh_tmp 目录下会生成 outpu.png 和 output.ply
3 执行 calibration_mian.py
4 查看执行的消息 


# 问题
def detect_marks_roi(im_project, show=False):
    masks = []
    # ???
    offset = 40

 


# camera_driver 
相机驱动代码
## 编译
拷贝到虚拟机编译环境
cmake ..
make -j8
## 执行
将可执行文件 camera_driver 拷贝到目标机器
/root/calibration
chmod 777 ./camera_driver
./camera_driver
执行完成后在当前目录下生成 output.png 文件

# lidar_driver 
雷达驱动代码
## 编译
拷贝到虚拟机编译环境
cmake ..
make -j8
## 执行
将可执行文件 lidar_driver 拷贝到目标机器
/root/calibration
chmod 777 ./lidar_driver
./lidar_driver
执行完成后在当前目录下生成 output.ply 文件

# sh 脚本
## 安装
安装前需关闭代理
pip install paramiko scp -i https://mirrors.tuna.tsinghua.edu.cn/pypi/web/simple
