INTEGRATION OF OPTICAL AND ACOUSTIC SENSORS FOR 3D UNDERwATER SCENE RECONSTRUCTION
نویسندگان
چکیده
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.

OPTO-ACOUSTIC DATA FUSION FOR SUPPORTING THE GUIDANCE OF REMOTELY OPERATED UNDERWATER VEHICLES (ROVs)
Remotely Operated underwater Vehicles (ROVs) play an important role in a number of operations conducted in shallow and deep water (e.g.: exploration, survey, intervention, etc.), in several application fields like marine science, offshore construction, and underwater archeology. ROVs are usually equipped with different imaging devices, both optical and acoustic. Optical sensors are able to gene...
متن کاملSegmentation of 3D acoustic images for object recognition purposes
|This paper addresses the problem of segmenting 3D acoustic images for object recognition purposes. For remotely operated vehicle (ROV) navigation the 3D surroundings have to be understood. Sensors, such as 3D acoustic imaging sensors, can be used for this purpose. Automatic segmentation and reconstruction of an underwater scene could make many underwater operations more e ective and reliable. ...

This paper presents a sensing method to measure three-dimensional (3-D) information in an underwater environment using an acoustic camera. Acoustic cameras can acquire clear information even in turbid water which is difficult to photograph with an optical camera. In addition, its detection range is extensive. Compared to traditional sensors, acoustic cameras with no restrictions on vision are t...
متن کاملSurface Reconstruction: Online Mosaicing and Modeling with Uncertainty
A burst of research has been made during the last decade on 3D Reconstruction and several interesting and well-behave algorithms have been developed. However, as scanning technologies improve their performance, reconstruction methods have to tackle new problems such as working with datasets of large dimension and building meshes almost in real-time. We pointed out a general need for formal anal...
