The HERON AC-1 is your companion for fast and professional 3D survey of big areas. The HERON AC-1 is the professional indoor / outdoor real time 3D mapping, localization and change detection system. The HERON AC-1 is capable of real time 2 cm resolution 3D mapping almost everywhere with 2 cm local accuracy and 5 cm global accuracy. This comes with the ability for higher resolution scans to then be automatically registered on the HERON point cloud when requested. The HERON AC-1 can be used nearly anywhere especially where use of a static scanner is impossible or when you need a quick 3D view of big areas. The HERON AC-1 is absolutely revolutionary in underground sites as it does not require GPS / GNSS, targets, trolleys and calibration stops to work!
