Monitoring degeneration

The analysis of the geometry and position of objects reveals much about their condition.

Overhead line, recorded with cameras at 150 km/h. The geometry is recognized and measured by special filters. As a result, the exact residual thickness of the wire can be determined.

The 3D and 2D geometry of an object provides comprehensive information about its shape or condition. The comparison of the geometry and location of the object over several measurement campaigns provides information about the dynamics of the change over a longer period of time: If, for example, the paving stones of a road are damaged, they slowly sink. Depending on the degree of subsidence, the road should be repaired or even renewed. Skilful evaluation of geometric data provides this type of information.

For geometrical data analysis we use special algorithms for edge detection or target/actual comparisons directly in the 3D model. A traffic infrastructure such as railway lines can be checked together with its many individual objects – poles, platforms, overhead lines, etc. – at regular intervals and their condition automatically evaluated. This makes predictive maintenance possible.

Systems for infra-
structure monitoring

Our systems provide detailed information on the geometry and location of infrastructure objects and the condition of their surfaces.
