Camera control method and device in three-dimensional GIS (geographic information system) roaming

Abstract

The invention discloses a camera control method and device in three-dimensional GIS (geographic information system) roaming. By the camera control method and device, the problem of penetration of cameras can be effectively solved. The method includes judging whether a collision curved surface covering a to-be-collided object exists at the longitude and latitude where a camera is located or not; if yes, further judging whether the camera collides with the to-be-collided object or not; if yes, moving the camera to the collision curved surface and enabling the camera to move along the collision curved surface, and if not, enabling the camera to move in an original state. Therefore, the camera cannot penetrate the to-be-collision object, and the problems that penetration of the camera occurs and the camera flies out of the ground are avoided. If the collision curved surface does not exist, a collision curved surface can be generated on the surface layer of the to-be-collided object, and then steps for judging whether the camera collides with the to-be-objected object or not and adjusting the camera are performed, so that the problems that penetration of the camera occurs and the camera flies out of the ground due to the fact that the camera penetrates the to-be-collided object due to failure to create the collision curved surface in advance are avoided.

Description

technical field [0001] The invention relates to the field of three-dimensional roaming, in particular to a camera control method and device in three-dimensional GIS roaming. Background technique [0002] Virtual reality technology comprehensively utilizes computer graphics, simulation technology, multimedia technology, artificial intelligence technology, computer network technology, parallel processing technology and multi-sensor technology to simulate the functions of human sense organs such as vision, hearing and touch to create a virtual environment. , enabling people to immerse themselves in a computer-generated virtual realm and interact with it in a natural way in real time. [0003] During the interaction with the scene, the movement of the viewpoint can be called walking. The viewpoint is equivalent to the camera of the roamer participating in the system, and the scenes recorded by the camera can be regarded as the world in the eyes of people. Considering the reali...
