Overview… UAV-mounted small Lider system Specialized for terrain measurement Rich LaserScanner specifications Rate: 40,000 points/second, Distance: Reflectance 30% to 250m, Field of view: 90° Distance measurement accuracy: 6mm at 50m, 20mm at 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 layer of the trees can be captured, and measurements of the ground surface cannot be performed. The Lider system uses lasers to measure the ground by passing through gaps in the trees. By directly measuring both the surface layer of the trees and the ground surface data and performing filtering, it removes the trees and creates terrain map data (DEM) necessary for civil engineering design and other applications.

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 topographic 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 situation of the work, the required objectives, and accuracy, ranging 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 handle 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-high-sensitivity cameras. Using photogrammetry technology, we connect individual photos to adjust the entire structure's image as an orthophoto (orthogonal projection image). It is possible to measure the position, extent, and approximate size of cracks and other features from the panoramic photos. Additionally, we can create a general longitudinal and cross-sectional diagram of the tunnel. 【Features】 - No need for large lighting equipment; we use compact imaging devices. - Minimal disruption to road traffic due to small team operations. - No noise or vibration. - Comprehensive understanding of the entire structure in a short period. - After shooting, calculations and processing take only a few days on a computer. - Three-dimensional models can also be created.

"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 work costs in depth measurements that require tide observations for each baseline, such as regular river cross-section surveys. 【Features】 ■ Tide observations are not required ■ RTK-GNSS method: Measurements are conducted with local benchmarks known - 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 tide observations or known reference points ■ Depth calculations based on traditional tide observations can still be performed For more details, please refer to the catalog or feel free to contact us.

"Depth and Shallow Water Survey Using Remote-Controlled Boat" utilizes an all-in-one remote-controlled boat (RC-3) equipped with D-GPS and built-in sonar, which automatically navigates along the survey line to measure water depth using its internal sonar. The single sonar has a depth measurement range of 0.5 to 80 meters, making it specialized for shallow areas. The navigation range is 800 meters, and the position is automatically navigated along a pre-specified baseline using D-GPS. The observation data is recorded as numerical data matched with the measurement location and water depth values. In areas where GPS signals cannot be received, position measurement is possible using an automatic tracking total station. [Features] - Enables surveys in shallow areas and hazardous waters that are difficult with manned boats. - Significantly reduces the risk of capsizing and falling accidents. - Environmentally friendly and clean considerations. - The boat is small and powered by an electric motor, eliminating exhaust and oil spills. - Observation can be conducted by one person for both navigation and measurement, reducing the number of workers compared to traditional methods.

"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. Even in situations where on-site work by humans is difficult, such as during disasters, high-precision drawings can still be created. 【Features】 ■ No need to ensure visibility of existing reference points, eliminating the need for activities like tree cutting. ■ Reduces the time and effort required to establish ground reference points. ■ The captured photos and GNSS measurement values are accurately determined through synchronization functionality. ■ The synchronization feature significantly streamlines the ground reference process.

Apeo Giken Co., Ltd. is a company primarily engaged in topographic surveys and measurements. From the air, we can conduct topographic surveys using multi-copter aerial photography, and 3D model creation is also possible. Additionally, we can enter the darkness of tunnels and other underground areas to capture photos of entire structures using ultra-sensitive digital cameras, enabling three-dimensional modeling and CAD representation in both longitudinal and cross-sectional views. We also accommodate various applications on the ground, such as stationary observations and water depth measurements. *For more details, please refer to our catalog or feel free to contact us.
