Mobile Mapping data processing

Mobile mapping data processing for Kempkes Landmeten

In short

Leica TRK, Ladybug 6 and Pegasus:Two EVO

Kempkes captures with a Leica TRK Mobile Mapping System, a Ladybug 6 panoramic camera and a Leica Pegasus:Two EVO. We turn those three sensor streams into one coherent dataset.

Anonymisation and QC included

Faces and number plates are detected and blurred automatically, followed by a manual pass over the exceptions. Not a separate budget line.

Open delivery, in your coordinate system

JPEG panoramas, LAS and LAZ point clouds, colourised point clouds, the vehicle trajectory and full metadata, in the client’s own coordinate system.

From sensor data to usable geo-information

On every run, panoramic imagery, LiDAR data and precise positioning are recorded at the same moment. Our automated pipeline brings those three sources together into one consistent, geographically accurate dataset. The result meets what municipalities expect from a mobile mapping project: simultaneous capture of panoramas and point cloud, accurate synchronisation between the two, and coverage that is complete.

The pipeline in four steps

First the trajectory computation, which fixes the driven route to centimetre level. Then registration, laying point cloud and imagery onto each other. Then colourising the point cloud from the panoramas. And finally anonymisation, where faces and number plates are detected by AI and blurred, with a manual round over the exceptions.

Quality control before delivery

Before a dataset leaves the building we check relative and absolute accuracy, image quality and colour rendering, completeness of coverage, synchronisation between imagery and point cloud, the metadata and the file structure. That is how the datasets meet the agreed requirements for image interval, point density, measurement accuracy and delivery quality.

Hoe het werkt

Standardised delivery

Deliverables come in open file formats that drop straight into GIS, CAD, BIM and asset management systems: 360° panoramas in JPEG, point clouds in LAS and LAZ, photorealistically colourised point clouds, the vehicle trajectory, image and point cloud metadata, point clouds split into standardised grids, and delivery in whichever coordinate system the client works in.

Built for large scale projects

Our pipeline is built for work at municipal and provincial scale. Every year we process thousands of kilometres of mobile mapping data, with speed, reproducibility and quality weighing equally. A high degree of automation moves datasets through quickly without giving up accuracy. For Kempkes that means shorter lead times towards his clients in the Rivierenland region.
