Data processing method and AR device

The embodiment of the invention discloses a data processing method and an AR device. The method is used for obtaining layout structure information of an environment where the AR equipment is located through an acoustic method. The method provided by the embodiment of the invention comprises the following steps: carrying out digital-to-analog conversion on a pre-stored first digital signal to obtain a test analog signal, and controlling a loudspeaker on AR device to play a sound wave corresponding to the test analog signal; obtaining a feedback analog signal corresponding to the feedback soundwave after the sound wave is propagated through a microphone on the AR device, and performing analog-to-digital conversion on the feedback analog signal to obtain a second digital signal; and finally,determining the propagation distance of the sound wave according to the first digital signal and the second digital signal, and further determining the layout structure information of the environmentwhere the AR device is loc
