Abstract
Combination of optical and acoustic sensors to overcome the shortcomings
presented by optical systems in underwater 3D acquisition is an emerging field
of research. In this work, an opti-acoustic system composed by a single camera and
a multibeam sonar is proposed, providing a simulation environment to validate its
potential use in 3D reconstruction. Since extrinsic calibration is a prerequisite for this
kind of feature-level sensor fusion, an effective approach to address the calibration
problem between a multibeam and a camera system is presented.Peer Reviewe
