Research And Application Of Color Scheme Recommendation System For River-crossing Bridge

The process of bridge color design is affected by many obstructive factors,such as inauthentic color display,incomplete environmental factors and unintelligent design decisions。Ultimately,the implementation of the scheme often depends on the designer’s appreciation level or past experience,the real color effects and bridge design error color,color scheme and surrounding environment is not harmonious.In view of the complexity of bridge color design,the design process of bridge color scheme is preliminarily divided into two stages: construction of color environment simulation system,recommendation of color scheme and system simulation.In the first stage,the key points of the color design of river-crossing bridge are summarized,so as to determine the controlled color source and the controlled color source.The types of the color design parameters and data requirements of the bridge under different urban environments are sorted out.Through UAV rapid mapping technology,the point cloud model and panoramic photos of the overall environment of the bridge are collected,and the BIM model of the bridge is overlacked.At the same time,different environmental parameter variables are set to complete the construction of the color scheme simulation system.The second stage takes color geography as the core theory and method,combines the principles of color coordination design,realizes color recommendation after algorithm recommendation combining real data and scene simulation,and simulates the recommendation scheme in the color environment simulation system.Finally,based on the design ideas and results of the color scheme system of the bridge across the river,a case demonstration of the color design function of Wuhan Jianghan Seventh Bridge,a landmark bridge across the river,is carried out.Based on in situ scenario simulation and real-world data,digital intelligent decisionmaking principle the basis of advanced technology and color such as geography,aims to explore the coordination,comprehensive and intelligent bridge color design scheme of system is formed,and in combination with the practical engineering background of the jianghan bridge seven complete solution test,hoping for the future of a bridge across the river in the color design of certain guidance.
