Yusheng Wang, Yonghoon Ji, Dingyu Liu, Hiroshi Tsuchiya, Atsushi Yamashita, Hajime Asama

RA-L 2021

A novel method to estimate the missing dimension in 2D acoustic images for 3D reconstruction is proposed in this paper. Acoustic cameras can acquire high resolution 2D images in underwater environment insusceptible to water turbidity and light condition. However, the formulation of acoustic images l

ACMarker: Acoustic Camera-Based Fiducial Marker System in Underwater Environment

Yusheng Wang, Yonghoon Ji, Dingyu Liu, Yusuke Tamura, Hiroshi Tsuchiya, Atsushi Yamashita +1

RA-L 2020

ACMarker is an acoustic camera-based fiducial marker system designed for underwater environments. Optical camera-based fiducial marker systems have been widely used in computer vision and robotics applications such as augmented reality (AR), camera calibration, and robot navigation. However, in unde
