In my Lab, we are considering buying a Google Tango development kit. But first we would like to make sure that we can get what we need out of it. From what I could check online, it is possible to acquire the pose estimate calculated by the device, along with the point-clouds acquired by its RGB-D camera. However, so far I could not find any references to acquiring raw IMU data, meaning the raw values obtained from the device's accelerometers and gyroscopes. Ideally, the raw IMU and RGB-D data would be timestamped; so that the IMU values can be integrated between the timestamps of two consecutive RGB-D images.
Is this even possible?
Is there any existing code already doing this for Google Tango?
Actually, I was talking to a colleague about this problem, and there are some Apps that already access the raw IMU data. As an example, the App Sensorstream IMU+GPS can acquire this data.
It is not yet clear to me what Android API calls need to be used to acquire it. However, I am sure now that raw IMU data can be acquired at least in the devices that have a proper integration with Android, and I guess that this must be the case of the Google Tango.
