The "Fixed 3D Laser Scanner" is a surveying instrument that can instantly acquire 3D coordinate (point cloud) data of objects such as terrain and structures using lasers, without touching the measurement target. Unlike traditional "single point" measurements, it enables 3D surveying in a "surface" manner through high-precision and continuous high-speed acquisition of point cloud data. It allows for safe, efficient, and effective work in measuring the volume of structures, measuring the displacement of tunnel cross-sections, and recording measurements at archaeological sites, disaster areas, and accident scenes. 【Features】 ■ Instantly acquires 3D coordinate (point cloud) data ■ Enables 3D surveying in a "surface" manner ■ Applicable in various fields ■ Allows for safe, efficient, and effective work ■ Data is in a simple XYZ text format *For more details, please refer to the PDF document or feel free to contact us.

"UAV" is an abbreviation for Unmanned Aerial Vehicle, which refers to small unmanned aerial vehicles. The advent of UAVs for surveying and photography has made it possible to investigate dangerous locations that were previously considered difficult, as well as the conditions at disaster sites immediately after an event. Additionally, due to their small size, UAVs can capture images in areas that traditional aircraft cannot approach, and they are currently being utilized in various fields of visual media. 【Examples of UAV Applications (Excerpt)】 ■ Aerial Photography (Still Image Capture) - Public Projects: Wide-area photography for initial surveys of disasters and design planning - Private Sector: Diagonal photography for CG compositing and capturing human formations at schools, etc. ■ Aerial Photography (Video Capture) - Public Projects: Using videos as explanatory materials for planning briefings - Private Sector: Materials for creating PR videos (landscapes, products), etc. ■ Photogrammetry (3D Surveying) - Public Projects: Materials for creating PR videos (landscapes, products), etc. *For more details, please refer to the PDF document or feel free to contact us.

The "Narrow Multi-Beam Depth Measurement System" is a multi-beam acoustic depth sounder that integrates a sonar unit (transmitter and receiver), a motion sensor (IMU), and surface water sound velocity (SV). Since sonar data, motion data, and sound velocity data come through a single cable from the underwater unit, complicated wiring is unnecessary. 【Features】 ■ Simultaneous three-dimensional measurement of underwater and above-ground ■ No complicated wiring required ■ Adopts Curved Array method ■ Frequency can be freely selected between 200 and 700 kHz ■ High-precision trajectory management is possible *For more details, please refer to the PDF document or feel free to contact us.

"UAV-LIDAR" allows for the measurement of forest topography and disaster-stricken areas that are inaccessible to people by utilizing drones (UAVs) equipped with laser scanners. Equipped with a laser (4 echoes), IMU (Inertial Measurement Unit), and GNSS, it can eliminate measurement errors caused by trees and vegetation, which have been challenges in UAV photogrammetry. Additionally, thanks to its ample flight time, it can perform the entire process from takeoff to alignment, scanning, and landing without the need for battery replacement. 【Features】 ■ Long flight time ■ Stable accuracy ■ Supports multi-echo ■ Advantage of being compact and lightweight ■ Laser measurement accuracy of ±4mm distance accuracy *For more details, please refer to the PDF document or feel free to contact us.

"Vehicle-mounted Photogrammetry Laser Measurement (MMS)" is a system that carries measurement instruments such as laser scanners, GPS, IMU, and optical cameras on a vehicle to continuously measure while in motion. By expanding the data obtained from each measurement instrument into the same coordinate space, it efficiently outputs accurate 3D point clouds and images. Calibration technology, which is used to maintain the accuracy of this composite system, is a feature of this system. 【Features】 ■ Acquires location information via GPS ■ Captures situations with a camera ■ Obtains 3D data using a laser scanner ■ Collects tilt and other data with an IMU and maintains GPS accuracy ■ Acquires 2 million points of point cloud per second *For more details, please refer to the PDF document or feel free to contact us.
