With the operation of the bridge intelligent perceptual cloud platform, the amount of perceptual data increases linearly with time. How to lighten the perceptual data and obtain the valuable information for the safety assessment of bridge structures has become an urgent problem to be solved. For this reason, taking the perceptual data of a long-span continuous rigid-frame bridge in an inland waterway as an example, the methods of lightweight data processing, analysis and data visualization are discussed in order to provide reference for better processing, analysis and display of bridge perceptual data.
