True View 635/640

Featuring RIEGL miniVUX-3UAV laser scanner, dual GeoCue Mapping Cameras and Applanix Position and Orientation System (POS) and includes post-processing software.

The True View 635/640 is a compact, survey-grade 3D Imaging Sensor (“3DIS”) designed for small Unmanned Aerial Systems (sUAS or drone). It comprises a survey-grade RIEGL laser scanner with dual photogrammetric cameras that have been carefully configured to provide a fused LIDAR/imagery field of view (FOV). The system includes full post-processing software that generates a ray-traced 3D colorized point cloud and geocoded images.

Description

True View® 635/640

The True View® 635/640 is GeoCue’s second generation of integrated LIDAR/camera fusion platform designed from the ground up to generate high accuracy 3D colorized LIDAR point clouds using the RIEGL miniVUX-3UAV. Featuring dual GeoCue Mapping Cameras, a Riegl miniVUX-3UAV laser scanner 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 615/620 provides high accuracy 3D color mapping with excellent vegetation penetration and wire detection in a payload package of 3.2-3.6 kg.

The RIEGL miniVUX-3UAV laser scanner provides range of up to 120m with up to five returns per outgoing pulse. The miniVUX-3 is RIEGL's update of the miniVUX-2, with selectable pulse Repitition Rate to 200,000 pulses per second.

True View EVO is the software used to post-process your raw flight data. EVO will generate a 3D LIDAR point cloud in LAS format, colorize the point cloud, and geotag the images collected. It is based on GeoCue’s LIDAR point cloud exploitation software, LP360, and comes with all the same tools as LP360 Advanced. Tools such as accuracy assessment, automatic and manual ground classification, and contour/ surface exporting.

True View EVO gives mappers and surveyors the ability to deliver high quality analytic data with exacting accuracies. True View EVO lets users ingest data from a True View sensor and process to end products without the need to employ other software applications. This is a huge reduction in workflow complexity and a big-time saver.
