To capture 3D environmental data as a basis for realistic simulations, a measurement vehicle equipped with the latest laser measurement technology has been developed.: the multi-sensor measuring system REDAR (Road & Environmental Data Acquisition Rover).

REDAR – Road & Environmental Data Acquisition Rover

In the course of the rapid development of technologies to capture 3D environment data, their consideration in the field of virtual product development of vehicles is becoming more and more important, which is accompanied by an increasing demand of high-quality data. The department MDF at the Fraunhofer ITWM deals especially with issues in the fields of load estimation and derivation of design targets for vehicles. The current challenge is the consideration of external influences on the vehicle load e.g. caused by the driver and the environment.

Current activities in the department MDF are focusing on method development for performing virtual test runs, integration of human behavior in virtual environments and invariant excitations of simulation models.Additional potential results from an improved detection of environmental influences. The goal is to lift the closeness to reality by the acquisition of the real environment and their most realistic representation (such as road surfaces and surroundings) in many areas of modeling andsimulation to a level which has not been achieved yet.

To capture 3D environmental data as a basis for realistic simulations, a measurement vehicle equipped with the latest laser measurement technology has been developed. This multi-sensor measuring system REDAR consists of the following main components:

  • inertial system with DGPS and distance sensor
  • laser scanners
  • high-resolution industrial cameras

The data recorded by REDAR can be used for example in the following applications:

  • digitization of real world proving ground for (multi-body) simulations
  • acquisition of the real environment for virtual 3D landscape and city models, especially for usage within the department’s driving simulator RODOS©
  • determination of road conditions and documentation
  • image capturing of the traffic area
