Abstract

Deflection is an important indicator of bridge health. This paper puts forward a deflection measurement system for bridge based on laser image technology. In the measurement progress, the laser image is sampled, filtered and converted to binary image using threshold segmentation, which is used to coordinate the center of light spot. The displacement of the location of light spot center relative to the reference position is used to calculate the deflection of bridge. The system has the features of high accuracy, low cost, and is suitable for continuous monitoring.
