This year, BBAUV has designed and developed a new vehicle, the Bumblebee 3.0, and one of the main enhancements is the addition of the new M900 imaging sonar. This will double the field of view (FOV) and the range and azimuth resolutions, and it’s compact form factor will allow the vehicle to be more streamlined. Our sonar imagery is fused together with camera imagery from a Guppy Pro camera. This is done by using a particle fitter based track before detect approach, and precise calibration, allowing Bumblebee to localize multiple objects in the water in 3D space with immense accuracy. The M900 will provide even better results for our algorithms.
