3D Visualization of Deep-Seabed Using a Stereo Vision System Applied into Underwater Vehicles
نویسنده
چکیده
JAMSTEC now has been developing several underwater platforms includes underwater vehicles as the useful tool to deal with various issues relating to the deep ocean. It is required that they are equipped with observation sensors to visualize deep-seabed including topography and benthic organism. One of methods to realize that is a stereo vision system. It can provide not only the 3D shape and color of shooting objects but also the geometric information if both accuracy of the camera model and the stereo matching are guaranteed. So we propose a method for 3D visualization of deep-seabed using the stereo vision system into underwater vehicle. As the result of sea trials applying it, detailed seabed conditions were visualized and the geometric information of shooing objects was measured.

متن کامل3D Surface Reconstruction of Underwater Objects
In this paper, we propose a novel technique to reconstruct 3D surface of an underwater object using stereo images. Reconstructing the 3D surface of an underwater object is really a challenging task due to degraded quality of underwater images. There are various reason of quality degradation of underwater images i.e., non-uniform illumination of light on the surface of objects, scattering and ab...
متن کامل3D Reconstruction of seabed surface through sonar data of AUVs
Autonomous underwater vehicles (AUVs) are widely used to explore the mysterious underwater world. Following along predefined spatial paths, AUVs are able to gather valuable seabed information in a designated area by recruiting sonar suites. The acoustic data collected by AUVs are usually in the type of point cloud with range information. Hence, how to reconstruct the topography of seabed via 3D...

This paper proposes a new technique to reconstruct large 3D scenes from a sequence of video images by combining Bayesian filtering and state-of-art 3D computer vision. The approach performs the alignment of a sequence of 3D partial reconstructions of the seafloor thanks to the re-observations of passive landmarks by means of a linear Kalman filter-based SLAM approach. Landmarks are detected on ...
