SimActive has integrated a new LiDAR workflow into its Correlator3D product. The capability allows users to import a point cloud into the software and to perform registration with an image dataset. Using LiDAR as control eliminates the need for traditional ground control points (GCP) when processing the photos.

The registration occurs during aerial triangulation, leading to a precise alignment of imagery with the LiDAR data. Following this, Correlator3D can output colourised point clouds as well as seamless orthomosaics.

“Removing the need to manually tag GCP facilitates the integration of LiDAR data with imagery.” said Dr Philippe Simard, president of SimActive. “Our users can benefit from different data sources, with perfect co-registration.”

SimActive is the developer of Correlator3D software, an end-to-end photogrammetry product for the generation of high-quality geospatial data from satellite and aerial imagery, including UAV. Correlator3D performs aerial triangulation (AT) and produces dense digital surface models (DSM), digital terrain models (DTM), point clouds, orthomosaics, 3D models and vectorised 3D features.
