我是Android的初学者和Tango（我只是想说它是为了防止可能出现的错误）而且我正在使用Project Tango Tablet（黄石）。我想用它来抨击，这就是我想获取原始数据的原因。
目前我知道如何获得poseData和点云。我读到无法获得IMU和RGBD。但是，不是RGBD，而是通过一些样本显示的RGB图像可能是合适的，但我不知道得到它。我认为它可能适用于＆＃34; onFrameAvailable（int i）＆＃34;但我真的不知道如何获得RGB图片。
对于IMU数据，我看到EVENT_IMU有＆＃34; onTangoEvent（TangoEvent tangoEvent）＆＃34;。但它永远不会发生/从未被处理过它应该是一个高频事件吗？但是我处理EVENT_FEATURE_TRACKING（= 5）和EVENT_FISHEYE_CAMERA（= 2）所以＆＃34; onTangoEvent（TangoEvent tangoEvent）＆＃34;作品。 所以我的问题如下：
感谢您的回答

我忘了说，但我解决了我的问题。 Tango的API不允许获取原始数据（IMU和RGBD）。但是你可以通过TangoImageBuffer获得带有c api的RGB。你会得到一张MV21照片。您将能够转换＆＃34; RGB单像素中的每个像素＆＃34;然后在RGBA数据中转换此像素。
对于IMU，只需忘记Tango的API并使用android API。您可以轻松地获取它，然后将其传输到服务器。我的情况是我通过使用ros发布者来做到这一点。多亏了这一点，我能够获得500个姿势/秒，35点云/秒和900 IMU /秒之类的东西。 如果您对使用ros感兴趣，可以查看ROS Rviz visualization of Tango Pose data。
