True View® 635/640

The True View® 635/640 is GeoCue’s second generation LIDAR/camera fusion platform designed from the ground up to generate high accuracy 3D colorized LIDAR point clouds using the new RIEGL miniVUX-3UAV. Featuring dual GeoCue Mapping Cameras, and Applanix Position and Orientation System (POS), the result is a true 3D high accuracy imaging sensor (3DiS). With its wide 120° fused field of view, the True View 635/640 provides high accuracy 3D color mapping with excellent vegetation penetration and wire detection in a payload package of 3.2-3.6 kg.

True Track® Flightlines
Post-processing software uses positioning
system information to perform roll
compensation at the individual scan line
level. This allows flight lines to be flown
with reduced overlap, increasing platform
flight efficiency.

Google Processor

A Google® Coral TensorFlow Processing
Unit provides exceptional power as the
True View Central Control Unit (CCU). The
CCU coordinates all on-board functions of
the system.

Applanix Positioning

A sensor can be no more accurate than the position and orientation system (POS). GeoCue incorporates the industry’s most accurate and reliable UAV POS – the Applanix APX series. The True View 635 features the industry standard APX-15. For exceptional angular accuracy,
the True View 640 upgrades the system to the APX-20. APX post-processing is accessed via the included True View Evo
software, providing “pay-as-you-go” access to SmartBase and Trimble PP-RTX positioning services.
True Time Synchronization Fusing sensor data requires exceptional timing synchronization among the positioning system and all sensors. TrueView’s System Synchronization Unit (a GeoCue designed Master Clock), ensures sensor coordination at the microsecond level.

LIDAR Scanner

The RIEGL miniVUX-3UAV laser scanner
provides range of up to 120m with up to five
returns per outgoing pulse. The laser scanner
can focus 200,000 points per second into the
True View 120° cross-track field of view.
Dual Cameras

Two GeoCue Mapping Cameras provide a 120° cross-track 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.

Complete Workflow Software Included

GeoCue’s True View EVO software, bundled with every system, provides a complete post-processing workflow solution from
project creation through final products. Data are written to a USB memory stick on the True View sensor
and imported into True View EVO using a simple import wizard. Immediately upon import, you are presented with a map view of
the project, showing the complete flight path lines. Another wizard directly in EVO takes you through the Applanix POSPac flow, creating the high accuracy trajectory thatwill be used to position imagery and LIDAR points. Automated tools are included that make short work of defining the segments of the trajectory that you want to process into flight lines. Generation of LAS points and colorization are fully automatic. The system is so efficient you can move from raw data import to colorized point cloud for a 20 hectare/50-acre site in less than 20 minutes. Assessing, correcting and reporting geometric accuracy is critical to metric mapping workflows. True View EVO contains tools to
assess/report network accuracy according to American Society for Photogrammetry and Remote Sensing (ASPRS) standards, measure
hard surface precision and geometrically adjust LIDAR data.
