Research on Route Fitting Design Method Based on UAV Oblique Photography
In order to accurately and efficiently fit existing road routes,a route fitting design method based on UAV oblique photography is studied.The method uses the UAV equipped with multiple sensors to obtain the image data of the existing road from multiple angles,and generates the real 3D reality model with the help of ContextCapture software.Through this reality model,the 3D coordinate information of road edge line can be extracted in batches for route fitting design,and then the BIM model of existing road can be generated.In the validation and application of the Guangzhou to Shenzhen Section of the Beijing-Hong Kong-Macao Expressway reconstruction and expansion,the road BIM model generated by the method is compared with the real 3D model,and the results show that the two have a high degree of fit,which verifies the accuracy and efficiency of the method.The research results provide an innovative and efficient route fitting design method for highway reconstruction and expansion projects,and expand the application range of oblique photography technology in the field of expressway reconstruction and expansion.
