Roadstuds Retroreflectivity

Roadstud Retroreflectivity

 

Impulse Geophysics Ltd has designed a digital video system to automatically locate road studs and measure their Retroreflectivity Luminance (mcd.m-2.lx-1).

 

The system operates at traffic speed and the studs are illuminated by a high intensity LED source. The receiving CCD's are calibrated to reproduce comparable grey-scale outputs. The grey-scale values are converted to retroreflectivity luminance using Impulse Geophysics proprietary algorithms. Along with the automatic detection of the Roadstuds colour we can then determine whether the stud is working as intended. 

 

Outputs are Geo-Referenced in CSV, Mapinfo Tables or Shapefiles format.
