Abstract:With the rapid development of computer image processing software (Boujou, Adobe Illustrator, Adobe After Effects, Adobe Premiere Pro) and drone technology, the visualization technology has been widely applied in road design, which greatly improve the efficiency and quality of traditional design. For example, in the early stage of road design, the application exploration of road red line visualization technology is to use the drone aerial photography technology and the above computer image processing software to draw the planned red line in aerial photo video or images in order to better display the planning scope and land acquisition of the projects and more truthfully and intuitively display information of building demolition and intersecting roads of the projects.
