Road Environment

Construction planning, inventory, maintenance: We supply the data

Our urban infrastructure is constantly changing: buildings are being built or demolished, trees and shrubs are growing or being pruned, environmental influences lead to a constant change of characteristic object parameters. Whether it's to adapt to heat, more frequent heavy rains, or to develop infrastructure such as fiber-optic networks: construction is necessary. However, construction projects can only be carried out efficiently if current and reliable environmental data is available. For cost reasons, most construction measures today are usually planned on the basis of existing, but unfortunately often outdated data (e.g. land registers). In the rarest of cases, current data is acquired and included in the planning process, although this promises a great deal of added value.

Our measuring systems record urban environmental data easily and cost-effectively. They depict a variety of objects, from buildings to infrastructure such as lanterns, manhole covers or kerbs and even vegetation. Surface structures such as different road surfaces – paving stones, asphalt, etc. – can also be recognized in the measurement data.

Mobile Urban Mapper MUM


With its Mobile Urban Mapper MUM system platform, Fraunhofer IPM offers the complete integration of several high-end measurement systems into an integrated workflow for the fast acquisition of 2D and 3D data of the environment. MUM is a modular system platform that can be tailored to the respective task.

The MUM system comes equipped with our Mobile Precise Scanner MPS and can also operate with commercial LiDAR sensors. The MPS 360° profile scanner can generate up to three million measurement points per second. It scans at frequencies ranging from 10 to 300 Hz, with a distance resolution of one millimeter. Multiple scanning heads and other commercial LiDAR sensors can easily be integrated and synchronized. 

Several high-resolution cameras are used for capturing the environment and texturing the point cloud with RGB information. State-of-the-art positioning technology, such as DGPS, IMUs and odometers, guarantee the precise calculation of the mobile platform's position and posture, thus delivering a consistent, georeferenced point clouds. High-precision calibration and temporal synchronization of all sensors allow for the fusion of all data streams.

Our multispectral Clearance Profile Scanner CPS-Plus can also be integrated to detect moisture or vegetation.

Fully automated data evaluation

Typically, data collected using mobile mapping systems is evaluated manually. With the 3D-AI software framework, we provide an efficient, automated evaluation tool. The software uses AI- and geometry-based algorithms to analyze 2D and 3D measurement data. 3D-AI identifies typical object classes from urban environments and surface textures, as well as geometric dimensions.

AI-driven software enables better and more efficient parking space planning

To plan parking spots efficiently, authorities need precise data the street width, which  determines whether vehicles can park on one or both sides of a street. As part of the "KI4Straßenbreite" project we have developed new software that enables automatic and comprehensive street width detection.

Sensor box provides real-time geodata for digital urban planning

A mobile sensor box developed at Fraunhofer IPM collects highly accurate 3D geodata. Mounted on buses, taxis, or garbage trucks, the box allows the urban environment to be recorded at frequent intervals without the need for special measurement vehicles. The captured data provides the data for digital urban twins.
