Sensor Fusion, by Design
True View® 515
The True View® 515 is GeoCue’s latest addition to our LIDAR/camera fusion platform designed from the ground up to generate high accuracy 3D colorized LIDAR point clouds. Featuring dual GeoCue Mapping Cameras, Hesai PandarXT-32 laser scanner and Applanix Position and Orientation System (POS), the result is a true 3D imaging sensor (3DIS). With its wide 120° fused field of view, the True View 515 provides high efficiency 3D color mapping and will redefine LIDAR wire extraction and dense vegetation penetration applications for all- purpose grade sensors.
Two GeoCue Mapping Cameras provide a 120° field of view, coincident with the laser scanner track. The 25° oblique mounting ensures the sides of objects are imaged, allowing a true 3D colorization of all LIDAR points.
The PandarXT-32 laser scanner provides range of up to 100m with two returns per outgoing pulse. High sensitivity enables superb detection of wires and ground beneath vegetation.
A Google® Coral TensorFlow Processing Unit provides exceptional power as the True View central controller. The CCU coordinates all on-board functions of the system.
A sensor can be no more accurate than the position and orientation system. GeoCue incorporates the industry’s most accurate and reliable POS – the Applanix APX series. APX post-processing is accessed via the included True View software, providing “pay-as-you-go” access to SmartBase and Trimble PP-RTX positioning services.
True Track® Flightlines
Post-processing software uses positioning system information to perform roll compensation at the individual scan line level. This allows reduced overlap between flight lines, increasing platform flight efficiency.
True Time Synchronization
Fusing sensor data requires exceptional timing synchronization among the positioning system and all sensors. True View’s System Synchronization Unit (a GeoCue designed Master Clock), ensures sensor coordination at the microsecond level.
