Abstract: The present invention discloses a dynamic interactive simulation method for recognition and planning of an urban viewing corridor. The method includes: constructing a sand table of morphology data of an urban space around an urban viewing point; creating a visual sphere, calculating a blocking point set, acquiring a three-dimensional view field of the viewing point, and obtaining an effective projection plane of a sight line of the viewing point; extracting a visual three-dimensional road model, calculating projection curvatures of road centerlines at points equidistant from each other, and screening and recognizing a viewing corridor; collecting a real scene, and inputting the collected real scene to a three-dimensional interactive display platform; inputting a new planning scheme to the three-dimensional interactive display platform, and simulating an urban viewing corridor with the planning scheme superimposed; and outputting, by using augmented reality glasses, a dynamic interactive VR scene of the urban viewing corridor space after the urban planning scheme is superimposed. The present invention combines a real dynamic viewing process, and uses a three-dimensional interactive display platform for planning simulation and interactive output, thereby providing a basic rational support for further optimization and decision-making of urban planning and design.
