TDOT 7 NIR

Integrates our laser scanner system "TDOT" with RIEGL's "miniVUX-3UAV" which is a maximum of 300,000 pulses per second and 100 lines.

The greatest feature of the TDOT series is the ability to continuously perform the process from flight using the high-performance GNSS/INS combined navigation system to output of point cloud data specialized for surveying.

The laser scanner system "TDOT 7 NIR" which has long-awaited functions such as high accurate real-time positioning analysis using LTE wireless communication and addition of temperature information to point cloud data by visible and thermography cameras was created

GNSS/INS

Achieving Higher Surveying Performance
Highly accurate positioning of the position, attitude, and direction of the drone
Built-in high-performance GNSS/INS combined navigation system with improved data output rate

Selected viewing angles important for surveying

The requirement for drone laser surveying is accuracy of elevation.

The surveying accuracy of elevation values is the accuracy of GNSS plus the laser ranging accuracy, but the farther the scan angle is from the vertical direction, the greater the surveying accuracy of the attitude at the time of laser irradiation affects the accuracy of elevation values.

The miniVUX-3UAV, which has a 360°FOV (field of view), cuts the surveying area because the laser hits the drone body at 180° in the upper half and the amount of data increases.

Two types of FOV selectable: Downward 120°with high surveying accuracy and high laser intensity, and downward 180°useful for structures such as buildings, bridge piers, dams, and overhang-shaped topography.

Equipped with visible camera and thermal camera (Optional)

Visible camera can generate orthoimages and add color information to the acquired point cloud data.

A thermal camera is used to detect temperature information that cannot be determined by a 3D point cloud.

It performs a visualization effect that visualizes relationships, characteristics, and trends that have not been seen before.

Seamless kinematic processing

TDOT series provides a system that seamlessly builds a series of tasks, from automating optimal trajectory analysis using fixed stations that require knowledge to outputting point cloud data.

TDOT 7 NIR can perform conventional kinematic processing without RTK.
