In this project, we are estimating the shape of a room:
-
The rooms are limited to shoe box shaped rooms
-
Simulate room impulse responses (RIR) using a RIR generator based on the image source model
-
Use multiple microphones inside the feasible region
-
A single loudspeaker is the sound source
Idea: Locate the set of first-order echoes from the recorded RIRs, and this set uniquely specifies the room walls with probability 1. In other words, almost surely exactly one assignment of first-order echoes to walls describes a convex room.
The success of this task largely depends on the accurate modelling of the early reflections, since it relies on learning from which wall a particular echo originates.
Finally, we reconstruct the geometry of the room using the intersection of the identified walls.
