Detecting and selecting proper landmarks is a key issue to solve Simultaneous Localization and Mapping (SLAM). In this work, we present a novel approach to perform this landmark detection. Our approach is based on using three sources of information:

The fusion of several images of the same scene into a single and larger composite is known as photomosaicing. Unfortunately, the seams along image boundaries are often noticeable, due to photometrical and geometrical registration inaccuracies. Image

Mosaic construction from side-scan sonar: A comparison of two approaches for beam interpolation

Autor: Alejandro F. Rozenfeld, Sebastian A. Villar, Rafael Garcia, Gerardo G. Acosta, Ricard Prados

Publikováno v: 2015 IEEE/OES Acoustics in Underwater Geosciences Symposium (RIO Acoustics).

This paper presents a unified methodology for the mosaic construction of the seafloor from side-scan sonar (SSS) imagery. This methodology applies techniques in SSS data correction to compensate the sonar beam pattern and the motion of the vehicle tr

Underwater 2D Mosaicing

Autor: László Neumann, Ricard Prados, Rafael Garcia

Publikováno v: Image Blending Techniques and their Application in Underwater Mosaicing ISBN: 9783319055572

The current chapter describes the main steps involved in the photo-mosaic building process. These steps comprehend the geometrical registration and warping of the images into a single common reference frame, along with an estimation of the topology o
