校准闪存

此示例演示了如何将版本 6（gen2 校准数据）的校准数据闪存到设备。

类似示例：

演示

示例脚本输出

Command Line

1~/depthai-python/examples$ python3 Calibration/calibration_flash.py
2    设备上的校准数据已备份到：
3    /home/erik/Luxonis/depthai-python/examples/Calibration/depthai_calib_backup.json
4    # 校准闪存成功

设置

请运行安装脚本以下载所有必需的依赖项。请注意，此脚本必须在 git 上下文中运行，因此您必须先下载 depthai-python 存储库，然后运行脚本

Command Line

1git clone https://github.com/luxonis/depthai-python.git
2cd depthai-python/examples
3python3 install_requirements.py
