大大，Android APP可以加个手动调节焦距的功能吗？ #41

沈大大好，最近使用了您的APP，在做双目定位方面的工作，但是双目有的时候需要固定相机的焦距，您有时间的话方便加这个小功能吗？

ligaoqi2 commented 1 year ago

现在APP是自动调焦的，估计深度和3D点坐标需要固定下相机的焦距

shenyaocn commented 1 year ago

点开调整菜单，设备支持的话可以切换手动/自动对焦。

大大，您说的调整试过了，现在在实验过程中，调焦里那里有一个方框的对号，然后点击的话取消不掉，这个的意思就是定焦吗？还是他本身是自动调焦，取消不掉的

shenyaocn commented 1 year ago

如果是有钩的方框取消不掉说明支持自动对焦但是不支持手动，如果钩不上说明只支持手动对焦。

大大，还想问您个问题，就是我目前的oppo手机(手机原系统)可以同时打开两个usb摄像头，但是用小米手机(刷机成魔趣系统)就只能打开一个，并且其中一个显示uvc设备错误-354，这是魔趣系统的原因吗？是不是刷回小米系统好些

可能是底层没适配好，或者手机供电不足，建议给hub加个外置电源输入试试。

对，如果你使用USB集线器从一个端口分配两个USB设备，两个设备同时又需要很大带宽就会出现这个问题，有两个独立的USB口直连主机就不会，两个USB口分别连接主机内部的两个USB集线器。

对，如果你使用USB集线器从一个端口分配两个USB设备，两个设备同时又需要很大带宽就会出现这个问题，有两个独立的USB口直连主机就不会，两个USB口分别连接主机内部的两个USB集线器。

大大，抱歉打扰您，就是我现在连了两个usb设备后，显示-256/no space left on device UVC设备错误，查了下，说是带宽不够，会有这个问题吗？

可能是底层没适配好，或者手机供电不足，建议给hub加个外置电源输入试试。

大大，还想问您个问题，就是我目前的oppo手机(手机原系统)可以同时打开两个usb摄像头，但是用小米手机(刷机成魔趣系统)就只能打开一个，并且其中一个显示uvc设备错误-354，这是魔趣系统的原因吗？是不是刷回小米系统好些

如果是有钩的方框取消不掉说明支持自动对焦但是不支持手动，如果钩不上说明只支持手动对焦。

大大，您说的调整试过了，现在在实验过程中，调焦里那里有一个方框的对号，然后点击的话取消不掉，这个的意思就是定焦吗？还是他本身是自动调焦，取消不掉的
