Phantom 4 UAS using Correlator3D software
SimActive’s Correlator3D is being used in Japan for mapping projects on the DJI Phantom 4 quadcopter UAS, the company announced on 6 August.
The equipment is being to validate the accuracy of the UAS for survey operations. A full-scale validation was carried out in the mountains near Hiroshima with a unit flown by SimActive Japanese partner Mirukuru and customer Ace-1.
According to the company, the area was surveyed by two independent flights at different altitude to assess consistency using Correlator3D’s change detection module. The analysis was simple to achieve, and 3D profiles showed no bias and very limited noise.
The Correlator3D software is an end-to-end photogrammetry solution for the generation of high-quality geospatial data from satellite and aerial imagery, including UAS. The software performs aerial triangulation and produces dense digital surface models, digital terrain models, point clouds, orthomosaics, 3D models and vectorized 3D features. Powered by GPU technology and multi-core CPUs, Correlator3D offers advanced processing speed to support rapid production of large datasets.
Shinji Inaba, technical manager at Mirukuru, said: ‘Considering that the data were acquired and processed directly in the field in a record time, the level of detail that are visible and measurable in Correlator3D is stunning. We had independently set up five check points and the residuals are consistently in the 5cm-range, both horizontal and vertical.’
