To ensure high accuracy Aerometerex partnered with a surveying company to measure 10 ground control points within the area of interest (AOI).

An initial aerotriangulation (AT) is performed to calculate image positions and generate a sparse point cloud. The results are reviewed by an AT specialist, with any errors corrected. Ground control points (GCPs) are then imported, and the AT is optimized for accuracy. Multiple checks using GCPs and checkpoints ensure the model meets required precision.

Once validated, the images and positional data are processed through Itwin Capture Modeller on a cluster of nodes, generating the 3D model in a tiled format. Quality control checks are carried out at various stages throughout the data capture and production process, by a team of dedicated quality control staff, in adherence to company methodologies and standards.

In a helicopter we capture from multiple angles within the project area. This ensures that every side of buildings and other assets are given equal focus and deliver a far superior result than other methods.
