传感器数据Collection
Collect sensor data from your device
WithMATLAB®Mobile™orMATLAB Online™, you can collect sensor and camera data from your Android™ device and log the data in MATLAB. Use MATLAB to process this data in various ways, including creating plots, or, for camera data, process the images.
You can collect data from these sensors:
Acceleration
Angular velocity
Magnetic field
Orientation
Position
You can also access the camera and acquire images on your Android mobile device fromMATLAB MobileorMATLAB Online. You can set camera properties including resolution, autofocus, and flash.
