Specifications
Automated Crack Recognition System (ACRS)
Overview
C-Map Systems Automated Crack Recognition System classifies distress on traveled surfaces in real time. The system can be used with customer source code to report pavement surface distress based on customer detection algorithms. The system supports two cameras such that image analysis may be performed with either the front vehicle mounted camera, or the rear mounted camera. The ACRS system performs well in low light situations. Artificial lighting is not required.
