Traffic Signs Mapping

Data collection through mobile mapping

Mobile mapping systems are vehicle-mounted, multi-camera imaging systems that create 360 ° panoramas at certain times or distances while driving.

The recorded data can be used for many applications. The exact detection and localization of traffic signs on the roadside is of great importance for municipalities and their road traffic authorities. In particular, since there can be a large number of traffic signs even in the smallest space next to each other.

Cataloging of traffic signs according to StVO

Tama Group introduces an application that performs the evaluation of the captured panoramas in a fully automatic way.

The traffic signs are not only geometrically and spectrally recognized and arranged; the collection goes up to complete cataloging with the correct traffic sign number according to StVO. Not only are color properties extracted from the image, but also geometric and topological properties of the objects are used for classification.

Processing large amounts of data

In a subsequent step, the user of the traffic sign application can use an interactive interface to check the correctness of the classification and, if necessary, to manually correct incorrectly recorded or unrecorded traffic signs.

In order to guarantee the processing of large amounts of data, the software offers the possibility of running the processing in parallel across several servers. There are hardly any limits to the scalability of this server-side process chain.

Through the savvy use of the Tama Group traffic sign application, the traffic signs captured by mobile mapping procedures can be quickly and efficiently classified and thus processed in a time-optimized process.
