In the insightful piece “Innovative DG Solutions – Elevating On-the-Fly Mapping,” Trimble Applanix delves into the revolutionary impact of direct georeferencing (DG) on UAV aerial mapping.
By integrating global GNSS corrections wiht aided-inertial navigation systems (aided-INS), this technology achieves centimeter-level precision without the need for base stations or ground control points. This advancement allows for the generation of accurate mapping data in real-time during flights or through automated post-processing shortly after landing, substantially enhancing workflow efficiency and minimizing field time.
The Synergy of lidar and Camera Technologies
Even though structure-from-motion algorithms can create 3D models from 2D images,they frequently enough face challenges in environments with dense vegetation,water bodies,or utility structures. The integration of LiDAR with DG offers direct and dependable 3D measurements. When combined with cameras or hyperspectral imaging devices, this technology allows for the colorization of point clouds and the correction of ortho imagery distortions, thereby improving both detail and accuracy.
streamlined Processing with Cloud Technology
Trimble’s POSPac Cloud® PPK engine, in conjunction with Trimble CenterPoint® RTX corrections and integrated into the DroneDeploy platform, facilitates post-processed centimeter-level accuracy through a cloud-based workflow. By logging dual-frequency GNSS data during flight, corrections can be applied via satellite or IP, significantly reducing the reliance on ground control. This method proves particularly beneficial for sectors such as construction, topography, and environmental monitoring, as it shortens setup times and accelerates data delivery.
Simplifying Accuracy in Mapping
By removing the need for ground-based reference points and providing automated correction workflows, Trimble Applanix makes high-precision mapping more accessible. The system is designed to alleviate the technical complexities for users, enabling results to be available within minutes of landing when configured correctly.This blend of automation, rapid processing, and accuracy is transforming the landscape of aerial data collection and utilization.
