Overview… UAV-mounted small Lider system Specialized for terrain measurement Rich Laser Scanner specifications - Rate: 40,000 points/second - Distance: Light intensity 30% to 250m - Field of view: 90° - Distance measurement accuracy: 6mm @ 50m, 20mm @ 150m Equipped with class-leading INS* - Horizontal accuracy: 10mm, vertical accuracy: 20mm - Attitude accuracy: Pitch/Roll 0.015° Characteristics… Why use a 3D laser scanner?! In photogrammetry, it is impossible to measure all terrain surfaces. While photogrammetry is common for UAV measurement content, photographs capture visible landscapes, so when trees are present, only the surface of the trees can be captured, and measurements of the ground surface cannot be performed. The Lider system uses laser technology to measure the ground by passing through gaps in the trees. By directly measuring both the surface of the trees and the ground surface and applying filtering, it removes the trees and creates terrain map data (DEM) necessary for civil engineering design.

The "Survey Service Catalog" is a service introduction catalog from Apeo Giken, which handles autonomous small unmanned aerial vehicles and autonomous unmanned survey vessels, conducting topographical surveys and depth measurements. It features various surveys that require special techniques, including the "UAV-mounted ultra-compact Lidar system" equipped with class-top-level INS. [Contents] ■ UAS (Unmanned Aircraft Systems) ■ Case studies using UAV measurements ■ Depth measurements ■ Photogrammetry ■ General surveying, etc. For more details, please refer to the catalog or feel free to contact us.

At Apeo Giken, we use GNSS surveying equipment to establish and inspect reference points that serve as the basis for map creation and various surveys. From public works to construction surveys, we provide a series of quality assurance tailored to the conditions of the work and the required objectives and accuracy, from actual measurements to precise observation planning and results adjustment. By adding a network system that utilizes communication and electronic reference points, we enable accurate three-dimensional positioning to be measured anytime and anywhere. We accommodate various measurement tasks according to needs, from network-based "immediate coordinates and elevation on-site" to static observations pursuing millimeter-order positional and elevation accuracy. 【Features】 ■ If there are no known points nearby, calculations can be made from electronic reference points. ■ Leveling surveys using GNSS are also authorized. ■ For surveys conducted by government agencies, we support everything from public survey applications to result verification. For more details, please refer to our catalog or feel free to contact us.

At Apeo Giken, we take continuous photographs in dark environments such as tunnels using ultra-sensitive cameras. Using photogrammetry technology, we connect individual photos to adjust the entire structure's image as an orthophoto (orthographic projection image). From panoramic photos, it is possible to measure the location, extent, and approximate size of cracks and other features. Additionally, we can create a general longitudinal and cross-sectional diagram of the tunnel. 【Features】 ■ No need for large lighting equipment; small photographic devices are used ■ Minimal road traffic restrictions due to small team operations ■ No noise or vibration ■ Comprehensive understanding of the entire structure in a short period - Calculation processing on a computer after shooting, with shooting and analysis processing taking a few days ■ Three-dimensional models can also be created For more details, please refer to the catalog or feel free to contact us.

"Network-type GNSS depth measurement" converts the terrain of the seabed into three-dimensional data using water depth measurements from sonar, starting from elevation acquisition with network-type GNSS. In particular, it can reduce operational costs in depth measurements that require tidal observations for each baseline, such as regular river cross-section surveys. 【Features】 ■ No tidal observations required ■ RTK-GNSS method: Measurements are conducted using known local benchmarks - Results can be created to match the elevation of the site ■ VRS-GNSS method: Utilizes the elevation of the nearest electronic reference point - Allows for seabed terrain measurement even without tidal observations or known reference points ■ Traditional depth calculations based on tide observations can still be performed For more details, please refer to the catalog or feel free to contact us.

"Depth and Shallow Measurement Using a Remote-Controlled Boat" utilizes an all-in-one remote-controlled boat (RC-3) equipped with D-GPS and sonar, which automatically navigates along the observation line and measures water depth using its internal sonar. The single sonar has a depth measurement range of 0.5 to 80 meters, making it suitable for shallow areas. The navigation range is 800 meters, and the position is automatically navigated along a pre-designated baseline using D-GPS. The observation data is recorded in a logbook as numerical data matched with the measurement position and water depth values. In locations where GPS signals cannot be received, position measurement is possible using an automatic tracking total station. 【Features】 ■ Enables surveys in shallow and hazardous water areas that are difficult for manned boats ■ Significantly reduces the risk of capsizing and falling accidents ■ Provides a clean and environmentally friendly approach - The boat is small and powered by an electric motor, eliminating exhaust and oil spills ■ Only one person is needed for navigation and measurement, reducing the number of workers compared to traditional methods For more details, please refer to the catalog or feel free to contact us.

"Non-GCP UAV Photogrammetry" enables the creation of high-precision 3D topographic maps even when GCPs (Ground Control Points) or reference points cannot be established. In addition to UAV flight control, it is equipped with the αUAV-mounted dual-frequency synchronized imaging system "GCSv3." This system allows for the assignment of high-precision position and elevation data to each digital photo taken. It enables the creation of accurate drawings even in situations where on-site work by personnel is difficult, such as during disasters. 【Features】 ■ No need to ensure the visibility of existing reference points, eliminating the need for activities like deforestation. ■ Reduces the time and effort required to establish ground reference points. ■ The captured photos and GNSS measurement values are accurately determined through synchronization. ■ The synchronization function significantly streamlines the establishment of ground references.
