Research and development of an open-source acoustic camera

The development of an open-source acoustic camera is described and assembled using commercially available hardware and freely accessible software, providing the potential for a more financially feasible kit assembly project. All developed code, components, and hardware are intended to be documented on a GitHub page along with full build instructions. The benefits and drawbacks of several digital beamforming methods, PCB design for audio purposes, and coding performant software on low-performing machines are discussed. Preliminary results for a sample prototype will be presented. The performance, accuracy, and limitations of the design are compared to commercially available solutions.
