B^2F-Map: Crowd-Sourced Mapping with Bayesian B-Spline Fusion

Yiping Xie, Yuxuan Xia, Erik Stenborg, Junsheng Fu, Axel Beauvisage, Gabriel E. Garcia +2

ICRA 2026poster

Crowd-sourced mapping offers a scalable alternative to creating maps using traditional survey vehicles. Yet, existing methods either rely on prior high-definition (HD) maps or neglect uncertainties in the map fusion. In this work, we present a complete pipeline for HD map generation using production…

Using Received Power in Microphone Arrays to Estimate Direction of Arrival

Gustav Zetterqvist, Fredrik Gustafsson, Gustaf Hendeby

ICASSP 2023accepted

Conventional direction of arrival (DOA) estimators are based on array processing using either time differences or beam-forming. The proposed approach is based on the received power at each microphone, which enables simple hardware, low sampling frequency and small arrays. The problem is recast into…
