DTSS is a vehicle-mounted camera system that captures both infrared thermography (IRT) and high-resolution visual images at highway speeds. The dual-imaging system is designed to detect both surface and sub-surface defects in the concrete bridge deck by detecting slight deviations in the temperature of deficient areas.
DTSS captures IR and high resolution visual images at highway speed which minimizes the need for traditional manual inspections that require inconvenient lane closures as well as exposing inspectors to unsafe environments. The high resolution visual data boosts the accuracy of the inspection by detecting surface deficiencies as well as acting as a ‘check’ to the sub-surface IR deficiency data. The visual image data would eliminate factors such as blotches on the road surface that would cause slight temperature differences that are not related to sub-surface defects.
