Abstract

Abstract: The vehicle-mounted mobile measurement system has the characteristics of fast acquisition of road data.Applying it to the generation of high-precision orthophoto images on the road surface can greatly reduce the measurement blind spots caused by the occlusion of vegetation,dense buildings and 3D structures of ground objects.In this paper,a method of generating orthophoto image of road surface based on vehicle mobile measurement system is proposed.The fisheye camera is innovatively used to solve the problem of limited observation field angle caused by low viewpoint of vehicle.The high-resolution image and high-precision point cloud data of the vehicle are fused to generate high-resolution and high-precision orthophotos.A set of road orthophoto generation schemes for the vehicle-mounted mobile measurement system is summarized,and the reliability and accuracy of the method are verified by experiments.

Key words: mobile measurement system, orthophoto, digital elevation model, ground filtering
