smart ROMEN CATCHER LY

Overview

smart ROMEN CATCHER LY has been developed as a concentration of Nichireki’s know-how relating to road management built up over many years, including state-of-the-art laser technology, non-contact sensor technology, and computer control technology.

Features

1. Flying spot method enables detection of road cracks at high speed
   Due to the flying spot method which utilizes a laser, all cracks 1mm or more in width are recorded while travelling at high speeds of up to 80km/hour.
2. Optical shut-off method provides precise data concerning rutting
   An optical shut-off measuring method is utilized which uses a CCD camera to record the images reflected from the laser beam that scans the road from directly above. The gathered imaging data is automatically analyzed by a real-time dedicated image processor to provide precise data regarding ruts.
3. Automatic analysis of high accuracy roughness data using non-contact displacement gauges
   The height from the road surface is detected using the reflection of the laser beam shining from directly above, and is recorded on video while superimposing the distance signals. Automatic analysis is carried out by a real-time dedicated image processor to provide high accuracy data concerning the roughness.
4. Provision of IRI data concerning the ride comfort as seen from the viewpoint of road users
   Longitudinal section profile data gathered from acceleration gauges and laser displacement gauges is recorded, and IRI (International Roughness Index) data is provided which is used for evaluating the ride comfort.
