设备信息

本示例展示了如何查询设备信息。代码的第一部分查询所有可用设备，而无需实际启动任何设备。对于找到的每个设备，它会打印以下信息：

设备名称：对于 OAK PoE 相机，为 IP 地址；对于 OAK USB 相机，为 USB 路径。
MxId：唯一的 Mx（芯片）识别码。
状态：设备的状态。请注意，OAK PoE 相机已烧录引导加载程序，该程序会初始化网络堆栈。

然后，该示例启动找到的第一个设备，并打印可用的相机传感器，同时读取校准数据和 EEPROM 数据，其中存储了产品名称和板卡名称。

Command Line

1正在搜索所有可用设备...
2
3找到设备 '1.3'，MxId: '18443010D116631200'，状态: 'UNBOOTED'
4找到设备 '192.168.33.201'，MxId: '184430102163DB0F00'，状态: 'BOOTLOADER'
5找到设备 '192.168.33.192'，MxId: '1844301011F4C51200'，状态: 'BOOTLOADER'
6
7正在启动第一个可用相机 (1.3)...
8可用的相机传感器: {<CameraBoardSocket.CAM_C: 2>: 'OV9282', <CameraBoardSocket.CAM_A: 0>: 'IMX378', <CameraBoardSocket.CAM_B: 1>: 'OV9282'}
9产品名称: OAK-D Pro AF，板卡名称 DM9098

这个示例需要DepthAI v3 API，参见安装说明。
