The latest photogrammetry techniques allow us to automatically generate a 3D reconstruction by combining sets of 2D images. The result generates fully scaled and geo-referenced models. Not only are the models centimeter accurate but are fully textured. The generated models have very rich detail from even a small amount of images. Examples of scans are shown below:
We have since carried out significant research into the optimal scanning techniques and now use improved camera and drone equipment. The resulting models are now comparable to LIDAR scans and only take a fraction of the time to capture.
