Visualising the seafloor on scales relevant for monitoring and planning
BioCam develops 3D visual imaging technology for seafloor mapping applications. The short range of most colour imaging systems typically requires underwater robots to carefully navigate underwater terrains at altitudes of just a few meters. BioCam leverage advanced in lighting and high-sensitivity detector technology, which allows colour imagery to be obtained from higher altitudes of up to 10 m, allowing faster-moving vehicles to be used and larger swaths of data to be collected. This allows sub-centimetre resolution 3D visual maps to be generated over orders of magnitude wider areas (see embedded videos), and this will give scientists and engineerings access to data products that cover the multi-hectare region spatial scales that are relevant to many monitoring and infrastructure planning applications. The long-range 3D imaging technology was also used by Team Kuroshio in the Shell Ocean Discovery Xprize, who won 2nd place in the grand final.
