Overview
The Alpha3D LiDAR payload provides geospatial professionals with a high-performance, vehicle-independent mobile mapping solution for capturing mass data in constantly evolving global environments. Projects are completed faster and more accurately to increase return on investment.
The Alpha3D combines an advanced long-range, high-speed, precise laser scanner, a high-resolution HDR panoramic camera in combination with cutting-edge GNSS receiver and high-precision IMU. All in one compact and lightweight, yet robust instrument. All these features make Alpha3D one of the most advanced and efficient 3D mobile mapping systems on the market today.
The high performance laser scanner allows for extremely high-speed scanning of 1M points per second and long range scanning of up to 420 m. It also offers high point cloud density even on high speed driving and with low range noise.
The Alpha3D is vehicle independent. It can be easily mounted on different types of vehicles, trains, railway trolleys and boats. Whatever the task is, the Alpha3D rapidly and efficiently collects high density, accurate point clouds and powerful images data, but also adds extra information from additional sensors, such as high-resolution camera, thermal camera, GPR, echo-sounder or extra profiler.
With a 30 MP HDR panoramic camera, the Alpha3D offers superb image quality with high resolution 360° images and supports fully calibrated point clouds. You can add additional image sensors to get any additional information your application needs.
Two RS232 ports can be used to connect external devices such as a second scanner for higher density point clouds and a second GNSS antenna to work on railway or water applications. The Alpha3D also offers an SSD hard disk for faster data transfer.
CHCNAV offers a complete package to add the LiDAR solution to users’ geomatics services. Fully automated reality capture and real-time mission monitoring using CoCapture field software and semi-automated point cloud processing using CoPre desktop software. Perform final feature extraction in Orbit GT software or use CoProcess CAD software.
