FTLF Series Long-Distance Crack Observation System
I. Instrument Overview
Traditional crack detection methods cannot meet the needs of rapid road development due to issues such as personnel safety risks, low efficiency, inaccurate results, and traffic disruption. The FTLF series long-distance crack observation system adopts high-precision optical systems and industrial CCD imaging technology. Through long-distance non-contact image acquisition, it directly extracts background subsets from original images, obtains crack background images using interpolation technology, subtracts background images from original images based on an additive model to get corrected results, and performs binarization processing on defect images after gray correction to extract defect information.
By adopting high-precision optical imaging systems and high-grade industrial CCD lenses, the FTLF series long-distance crack observation system truly realizes long-distance non-contact crack detection, with precise angle and distance detection capabilities that conventional non-contact crack detection methods cannot achieve, and truly achieves self-calibration and all-round detection at any angle.
II. Product Applications
It can be widely used for long-distance quantitative detection of crack widths in bridges, tunnels, buildings, concrete pavements, metal surfaces, etc.
