LIGHTWEIGHT
Lightweight TDOT 7 GREEN model
Easy and accurate laser surveying for everyone
The “TDOT 7 GREEN LITE” GREEN LiDAR system was developed in pursuit of an extremely light weight and compact design, yet with the same high-performance green laser module used in TDOT 7 GREEN.
TDOT 7 GREEN LITE realizes an outstanding level of agility that has been difficult to achieve using conventional Green LiDAR-equipped models, and enables a quicker response to a wider variety of sites.
In particular, it is also designed to be installed and operated on DJI’s “Matrice 350 RTK,”* which has been requested by many users, further expanding the flexibility of its introduction.
Combining high accuracy and mobility, the LITE model will raise the potential of drone surveying to the next stage.
*Users must submit the prescribed modification application to install TDOT 7 GREEN LITE on DJI’s Matrice 350 RTK.
GREEN LiDAR
Survey both land and the bottom of water bodies at once
Green laser technology enables TDOT 7 GREEN LITE
to survey land and the bottom of water bodies at the same time
Equipped with a green laser having a wavelength of 532 nm, TDOT 7 GREEN LITE can support underwater topographic surveying, which has been difficult for conventional LiDAR to offer.
The near-infrared laser beams used in standard LiDAR systems are absorbed the moment they touch water, preventing underwater topographic data from being acquired.
Green laser beams, however, penetrate water with extreme ease because they are resistant to absorption by water.
This characteristic ensures reliable data acquisition when surveying land areas, wet ground surfaces, construction sites, rivers and shallow water areas, and even extremely narrow water areas that are inaccessible to boats and other locations immediately after flood damage.
A lightweight yet high-performance green LiDAR system that can handle a wide range of situations, TDOT 7 GREEN LITE resolves the issues that surveying previously struggled to manage.
FOV
Cover a wide area at once with a 120° field of view
Survey expansive areas more safely in a single flight
The wide 120° field of view dramatically improves both efficiency and safety
TDOT 7 GREEN LITE offers a wide field of view of up to 120°, thereby enabling users to scan larger areas in a single flight.
This wide field of view also helps to significantly reduce the number of flights required for surveying, which directly improves the efficiency of the entire workflow.
Furthermore, it enables users to perform accurate surveys from a sufficient distance away, even in very risky locations that would typically need to be approached to survey using a narrow field of view, such as steep slopes and the sides of structures. It also protects site safety.
Improving work efficiency and protecting site safety the wide field of view design introduced for TDOT 7 GREEN LITE achieves both.
PHOTOGRAMMETRY
Acquiring image data
Record the situation at sites in color using the standard-equipped visible light camera
Also supports color point cloud and orthophoto* generation
For more “visible” surveying with photographs and point clouds
Also supports color point cloud and orthophoto generation with the visible light camera
TDOT 7 GREEN LITE comes standard with a visible light camera, which can be used at the same time as laser surveying to perform interval photography.
This model can generate “color point clouds” by superimposing the color information acquired from these photographs onto the point cloud data.
In addition, TDPT 7 GREEN LITE also supports the creation of orthophotos from location information based on photographic data.
This allows it to produce consistent results from both visual and spatial perspectives.
Using color and photographic information makes it much easier for stakeholders to understand post-survey analyses and explanations, thereby facilitating the understanding of sites and improving reporting document accuracy.
*Additional Structure from Motion (SfM) software is required to generate orthophotos.
