Trimble UX5 aerial image data can be processed into powerful deliverables with the Trimble Business Center (TBC) Aerial Photogrammetry module. The TBC Photogrammetry Module is based on state-of-the-art image processing technology. The incorporation of photogrammetric algorithms specialized for small UAS produces very accurate results automatically, with minimal manual interaction. This office software combined with the Trimble UX5 provides a reliable photogrammetric system delivering excellent results without requiring specialized photogrammetry knowledge or experience.
The TBC Aerial Photogrammetry module works seamlessly with the TBC Complete and Advanced software editions, making it possible to process complete survey projects including aerial imagery, Trimble VISION imagery, GNSS data, and total station observations.
The new Advanced UAS functionality is a completely automated workflow for aerial photogrammetry, allowing adjusting photo stations and creating deliverables all at once using one single command.
When ground control data is available, Trimble recommends running a 'Quick Fit' to roughly orient the photo stations. The Quick Fit will quickly adjust the photo stations to estimate their positions. In this way, the ground control markers can easily be identified.
When no control data is available, the deliverables creation can start immediately after loading the flight data.
TBC’s “virtual telescope” intersects points from multiple aerial photo stations and/or terrestrial Trimble VISION photo stations, to enable measurement of discrete points. Accurately and efficiently measure the locations of features including buildings corners, tree-tops, and utilities.
Automatically create 3D colored point clouds from adjusted photo stations. Based on 25 years of technology evolution, TBC’s point cloud generation algorithms are based on state-of-the-art Inpho dense matching and DTM generation software. The fully automatic process adapts parameters to guarantee precision, providing extremely detailed and accurate results at a speed of about 3 sec. per image with about 1-2 pixels height accuracy.
Automatically create 3D digital surface models and digital terrain models from adjusted photo stations. A raster DSM and DTM created from the generated point cloud is refined using sophisticated interpolation routines, noise filtering, edge modeling and outlier detection to achieve rich detail within surface and terrain models.
Automatically create classic orthomosaics generated from Digital Terrain Models or true orthomosaics generated from Digital Surface Models. Rigid “True-Ortho” rectification combined with outstanding geometric feature-based seamline-finding and radiometric balancing results in perfect looking seamless ortho-mosaics. Seams are adaptively blended according to image texture analysis. Radiometric single image corrections as well image group corrections are applied for perfect homogeneous colors and intensity, ready for GIS use. The automatic process only takes about 4 sec. per image.
