AARemu is a software tool enabling simulation of Augmented Reality    by allowing an AR developer to record a 360 degree view of a    location using the devices camera and orientation sensors (this    functionality is provided by the ARemRecorder app). The ARCamera    class which provides an impostor of the Android camera class    can then be used to preview the recorded scene instead of the live    camera preview provided by the Android Camera class. The ARCamera    preview callback is analogous to the standard Camera preview    callback except that the preview bytes provided in the callback    are extracted from a file created by the recorder application    based on the current bearing returned by the orientation    sensor(s). These preview bytes are passed to the development code    via the same preview callback as provided by the standard Camera    classes and can thus be processed by Computer Vision algorithms    before being displayed by the client application. The frames are    stored as individual video frames in RGBA, RGB or RGB565 format    and not as video so the preview can be accessed in both    clockwise and anti-clockwise directions.The tool is aimed at developers of outdoor mobile AR application    as it allows the developer to record one or more 360 degree    panoramas of a given location and then debug and test the AR    application in the comfort of a office or home without having to    make extensive changes to the programming    code.
