Integrates TDOT system and RIEGL laser unit
\n\t\t\t\t Created as a high-performance laser scanning system<\/h3>\n

Integrates our laser scanner system “TDOT” with RIEGL’s “miniVUX-3UAV” which is a maximum of 300,000 pulses per second \u203b and 100 lines.
\nThe 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.
\nThe 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.
\n\u203b100kHz \/ 200kHz \/ 300kHz laser pulse repetition rate (PRR) selectable.Surveying rate and FOV fluctuate depending on PRR.
\n\u203bSpecifications as of April 2023. For the latest information on specifications, please refer to the RIEGL’s official website.\n<\/p>\n<\/p><\/div>\n

GNSS\/INS<\/h2>\n

Achieving Higher Surveying Performance
\nHighly accurate positioning of the position, attitude, and direction of the drone
\nBuilt-in high-performance GNSS\/INS combined navigation system with improved data output rate<\/h3>\n

Laser surveying requires calculating how long it takes the laser beam to return from the object tens of thousands of times per second.
\nIn this process, the position to be irradiated with the laser beam is surveyed by GNSS, but it can only be surveyed several tens of times per second, resulting in a large error in the position of the target.
\nIn addition, it causes a positional deviation equivalent to the measurement error of the laser beam irradiation angle multiplied by the distance to the object.
\nTherefore, the farther the target is, the less accurate the coordinates of the target can be determined, even if the error in the irradiation angle of the laser beam is small.
\nThen, the accelerometer captures the movement of the drone, and the gyro sensor detects the constantly changing attitude of the drone.
\nThe combination of IMU (Inertial Measurement Unit) and GNSS is called GNSS\/INS combined navigation (inertial navigation) system, and by utilizing the advantages of each other, a highly accurate surveying system is completed.
\nThe INS of the TODT series has the specification to realize highly accurate surveying of several tens of millimeters while irradiating tens of thousands of laser beams per second.\n<\/p>\n

FOV<\/h2>\n

Selected viewing angles important for surveying<\/h3>\n

The requirement for drone laser surveying is accuracy of elevation.
\nThe 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.
\nThe miniVUX-3UAV, which has a 360\u00b0FOV (field of view), cuts the surveying area because the laser hits the drone body at 180\u00b0 in the upper half and the amount of data increases.
\nTwo types of FOV selectable: Downward 120\u00b0with high surveying accuracy and high laser intensity, and downward 180\u00b0useful for structures such as buildings, bridge piers, dams, and overhang-shaped topography.\n<\/p>\n

TDOT 7 SETTING<\/h2>\n

Renovated TDOT 7 dedicated application<\/h3>\n

Access TDOT 7 by communicating with a device that can use a browser, such as a tablet, via Wi-Fi.
\nDetailed settings such as ON\/OFF switching of laser settings, real-time cross section, visible camera, thermography, etc.
\nTDOT application has been renovated, such as viewing status information as before.\n<\/p>\n

REAL TIME DATA DISPLAY<\/h2>\n

Real-time display of data during surveying<\/h3>\n

Viewing data in real-time during surveying.
\nFor example, by displaying a cross-section of the object, it is possible to check in real time during flight the status of ground surface data acquisition under vegetation in areas where trees are thriving.
\nAs a result, it is possible to check on the spot whether the survey has been carried out as planned, and to carry out efficient survey work without rework.
\n\u203bTo view cross-sectional data during surveying, the drone must be equipped with an image transmission device that can be connected to HDMI.
\nIn the case of DJI’s Matrice300RTK, it can be viewed through DJI SkyPort.\n<\/p>\n

CAMERA\/THERMO<\/h2>\n

Equipped with visible light camera and thermography camera (Optional)<\/h3>\n

Equipped with visible light camera and thermography camera (Optional)
\nVisible light camera can generate orthoimages and add color information to the acquired point cloud data.
\nA thermography camera is used to detect temperature information that cannot be determined by a 3D point cloud.
\nIt performs a visualization effect that visualizes relationships, characteristics, and trends that have not been seen before.\n<\/p>\n

RTK<\/h2>\n

RTK with LTE wireless communication
Real-time analyzed point cloud data is transferred to the server on the spot<\/h3>\n
To be supported by version upgrade<\/div>\n

The LTE wireless communication module built into the TDOT 7 NIR and the high-performance single-board computer \u201cNVIDIA Jetson Xavier NX\u201d allow the scanned data to be analyzed and processed in real time and stored as point cloud data with positioning accuracy and accurate location information.
\nThe analyzed data is uploaded to a dedicated server in real time using an LTE line.
\nAcquired data can be viewed immediately from a remote location.
\nAll of this will be implemented as a long-awaited system that can run TDOT 7 NIR alone.<\/p>\n

Kinematic Processing<\/h2>\n

Seamless kinematic processing<\/h3>\n

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.<\/p>\n
