Imaging sensors in underwater robotics: Present and future trends. (Les capteurs d’imagerie en robotique sous-marine: Tendances actuelles et futures.) (French) Zbl 1035.94503
Summary: The two main visual sensors in underwater robotics are sonar and video. In a first part, we present the fundamentals of acoustic imagery. Although some techniques are well known, others, like synthetic aperture antenna, interferometry and parametric array are still research topics. In a second part, acoustic image processing techniques are presented. They are mainly applied to sea bottom characterization and robot navigation. The third part addresses video technology and processing. This sensor is complementary to sonar due to its high resolution and the ease of interpretation of the images.
