相机的名称异常
1、在设备管理器的照相机选项中：
- 底部相机的正确名称：TORNADO-V2 Bottom Camera
- 顶部相机的正确名称：TORNADO-V2 Top Camera
2、可能由于操作系统兼容性的问题：
- 底部相机会被错误识别为：HBVCAM Camera。
- 顶部相机会被错误识别为：USB HD Camera。
3、如何解决：
- 请前往下载上方我们提供的固件更新工具，
- 对名称有误的相机，进行做一次固件升级，即可一次性解决底部相机名称错误的问题。
4、准备工作：
- 准备工作：需要使用Windows操作系统电脑，下载并解压上方固件至文件夹，文件夹位置随意。
- 将相机全部接入电脑。
5、升级固件
- 以升级底部相机为例，顶部相机的操作，与下方操作相同；
- 运行解压后的底部相机刷机软件 UvcCamDownload.exe；
- 在Camera IC下拉列表中，选择任意选择一条相机的VID&PID信息；
- 如果VID&PID信息为底部相机的，软件会自动在上方加载并显示所需的固件；
- 点击Start按钮，开始升级，直至结束，当软件状态会显示为 PASS，即代表升级成功（下图所示）；
- 前往设备管理器，查看并确认当前连接的相机名称是否变为：TORNADO-V2 Bottom Camera；
- 如果名称未变化，请在该相机，鼠标右键-卸载设备，然后点击设备管理器上方的 扫描检测硬件改动 按钮；
- 让电脑重新识别一次该相机，此时，正确的名称便会显示出来。
