ACOUSTIC DEPTH MAP - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240310515 titled 'ACOUSTIC DEPTH MAP

The patent application describes a depth sensing apparatus that utilizes audio signals to generate a depth map of an environment.

• The apparatus includes an audio output device, at least one audio sensor, and processing devices.
• The audio output device emits an omnidirectional audio signal into the environment.
• The audio sensors capture echo signals reflecting the emitted audio signal from the environment.
• Spectrograms are generated using the echo signals and applied to a computational model to create a depth map.
• The computational model is trained using reference echo signals and depth images.
