We will first walk through the steps to simulate a shoebox-shaped room in 3D. We use the ISM is to find all image sources up to a maximum specified order and room impulse responses (RIR) are generated from their positions. The code for the full example can be found in examples/room_from_rt60.py.

Fast C++ implementation of the image source model and ray tracing for general polyhedral rooms to efficiently generate room impulse responses and simulate the propagation between sources and receivers;

2023年9月4日 · However, the conventional RGI technique poses several assumptions, such as convex room shapes, the number of walls known in priori, and the visibility of first-order reflections. In this work, we introduce the RGI-Net which can estimate room geometries without the aforementioned assumptions.

In mathematics, a convex space (or barycentric algebra) is a space in which it is possible to take convex combinations of any sets of points. [1][2] A convex space can be defined as a set equipped with a binary convex combination operation for each satisfying:

2025年2月7日 · We (i) propose a scaled bundle adjustment (SBA) formulation that lifts 2D keypoint measurements to 3D with learned depth, (ii) design an empirically tight convex semidfinite program (SDP) relaxation that solves SBA to certfiable global optimality, (iii) solve the SDP relaxations at extreme scale with Burer-Monteiro factorization and a CUDA ...

"Our software can build a 3D map of a simple, convex room with a precision of a few millimeters," explains PhD student Ivan Dokmanić. Randomly placed microphones

We show how to compute the shape of a convex polyhedral room from its re-sponse to a known sound, recorded by a few microphones. Geo-metric relationships between the arrival times of echoes enable us to “blindfoldedly estimate the room geometry. This is achieved ” by exploiting the properties of Euclidean distance matrices.
