Autonomous vehicle fuses sonar and GPS for precise seabed mapping

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new framework for seabed mapping in challenging shallow, turbid waters using autonomous surface vehicles. This system fuses sonar data with GPS and IMU readings, employing Fourier-Mellin transforms for local frame alignment and an extended Kalman filter for global trajectory optimization. Field trials demonstrated a 9.5% reduction in drift error compared to previous methods, enabling sub-meter reconstruction accuracy and high-resolution texture preservation crucial for applications like oyster inventory estimation.
