Autonomous Lidar and Imagery Data Collection

Lidar Systems

Fully autonomous and

The Optech Eclipse is the first autonomous airborne system to focus on operator-less data collection from tightly integrated passive and active imaging sensors on low-cost platforms. Designed specifically for the efficient data collection of smaller project areas and corridor applications, the Eclipse requires only a pilot for navigation.

The Eclipse combines an eye-safe, high-performance, 1.5-micron laser with a high-accuracy automatic imaging system for effortless collection of high-resolution lidar data and imagery via its innovative sensor motion detection system. Simply press the power button and the sensor automatically starts collecting data when the sensor is in motion. A small dash-mounted status bar feeds sensor status information to the pilot with LEDs and incorporates a simple switch to start recording data. Lidar and image data are simultaneously captured on a single high-capacity removable SSD cartridge for fast and efficient data transfer to Optech Lidar Mapping Suite (LMS).

LMS includes both lidar and image pre-processing within a single workflow, and employs robust least-squares algorithms to auto-calibrate lidar data and perform photogrammetric block adjustments. Relative and absolute accuracies are then quantified and data is output in a variety of formats. Included is a flight planning tool that leverages a digital globe for 3D planning purposes and generates flightline waypoints for direct ingestion into 3rd-party navigation systems.
