VANCOUVER, BRITISH COLUMBIA - LMI Technologies has introduced a new Selcom High Speed RoLine 1130 Sensor for high speed pavement profiling to the North American market. LMI Technologies has its headquarters in Vancouver, British Columbia, Canada and has offices in Sweden and The Netherlands.

The new Selcom RoLine 1130 Sensor is used to measure road profiles, road roughness and pavement smoothness and is used as a forum to exchange information between end users, data collections, vendors, construction and design engineers on the conditions of a particular road or highway.

The Selcom RoLine 1130 sensor features laser line sensing for accurate profiling of all pavement geometries on high-speed profilers at any vehicle speed. The laser line measuring principle of RoLine sensors was developed to improve the accuracy of pavement profiling for coarse textured surfaces, particularly longitudinal tined and diamond ground surfaces.

Based on the same sensor technologies used in the earlier RoLine 1100 sensors, the RoLine 1130 provides increased frame rates and higher data density to meet the needs of high-speed profilers on either concrete or asphalt surfaces.

To provide flexibility for the profiler manufacturer, the RoLine 1130 operates with two data output modes, either full profile data or the optional output using the internal bridging algorithm that reduces the full profile to a single point output representing the actual surface location. To achieve high speed operation, the RoLine 1130 is based on LMI's FireSync platform, a modular, extensible architecture which allows vision components, such as lighting, cameras, embedded sensor processors, and machine-vision software, to be easily integrated into a scalable machine-vision system. FireSync solves the classic problem of synchronisation between lighting, camera and processing modules to microsecond precision.
