Design And Implementation Of High Core Erial Mage Processing System For Highway Construction Project Management

Under the background of the current social and economic development in our country,the work of information-based city construction gradually plays an increasingly important role.One of the most popular information technology is city visualization,which promotes the current urbanization construction work in our country to gradually get good development and effect under the background of the full play of the current information technology.Visualization corresponding to the field of highway construction project management is to show the project under construction directly in front of the manager through scientific and technological methods or means,to help the manager better understand the construction progress,construction efficiency and other actual conditions of the highway construction project,so as to improve the work efficiency and management level of the highway manager.The main work of this dissertation is to establish an image processing system based on high-resolution aerial image data,and to track,check and analyze the projects under construction.The high-resolution aerial image is processed by means of atmospheric correction,radiometric calibration and other technical means,and the processed image is compared with the expected progress image,so as to get the actual construction progress of the road project under construction.The research results of this dissertation mainly include:(1)Select the appropriate image acquisition channel to obtain the original image data of the highway project under construction in China,and process the original image data by means of atmospheric correction,radiation correction and other technical means to obtain the normal image set of the highway project available for use.(2)Under the same specifications and standards,establish the image database,basic geographic information database,road network database,project business database,high score aviation special verification results database,and provide the data base for high score aviation image processing system.(3)A high-resolution aerial image processing system for highway construction project management is designed and implemented.The system includes high score image processing system,high score image analysis system,construction project verification system,support system and related interfaces.The high score image processing subsystem includes image vector map processing,image screening,data quality inspection,data quality inspection rule management,data correction and correction,and image storage.The high score image analysis subsystem includes image data visualization and image data management.The construction project verification subsystem includes construction project information recording,construction project verification,and the underlying support system package Including system management and data exchange and sharing module.After the completion of the system,the corresponding functional test is carried out.The test results show that the system can process high-resolution images and assist the project construction schedule management analysis.
