Embodiment approach

[0057] This article provides an implementation of establishing an interactive virtual shooting system. First, build a three-dimensional scene of the site to be shot, and then realize the purpose of loading various types of virtual cameras at different positions in the three-dimensional scene by loading related files. The human-computer interaction interface of the human-computer interaction platform is loaded into the 3D graphics simulation engine, which realizes the purpose of controlling the virtual camera in the scene through the human-computer interaction platform, and completes the preparation work before the human-computer interaction.

[0058] It is not difficult to understand that the interactive interface of the human-computer interaction platform can be created by means of Flash, Scaleform, etc. The camera setting file can be an XML format file.

[0059] During specific implementation, the selection of the virtual machine position and the type of the virtual camera u...

Abstract

The invention relates to a virtual camera shooting method. The method comprises: constructing an interactive virtual shooting system; selecting virtual machine positions and types of virtual cameras used at the virtual machine positions according to shooting demands; configuring camera shooting parameters of the virtual cameras, using the selected virtual cameras to shoot in a three-dimensional scene, and controlling shooting actions of the virtual cameras in the shooting process; and rendering pictures shot by the virtual cameras into a frame sequence, and outputting the rendered pictures. According to the method, shooting effects under different selections can be obtained according to selection of the different virtual machine positions and the virtual camera types, reference basis is provided for shooting works under real scenes, damage risks to equipment in the repeated transportation and mounting process are reduced, work efficiency and quality are improved, and the shooting cost and the time cost are reduced.

Description

technical field [0001] The invention relates to the technical field of simulation, in particular to a virtual camera method. Background technique [0002] The use of cameras in large-scale square rehearsals has ushered in new changes. The omnidirectional, three-dimensional dynamic, and large-scale rehearsal scenes make it impossible for a single type of camera and a small range of shooting angles to meet the needs of today’s large-scale square rehearsals. For all-round and multi-angle shooting and broadcasting, cameras need to be placed in different positions and angles. In order to show the program and content of the large-scale square rehearsal from all angles, fixed-point cameras, rocker cameras, orbital cameras, and flying cat cameras are needed. These devices are numerous and complicated to operate, with large volume and weight, and usually require very skilled photographers to operate. Even so, it is necessary for the photographer to rehearse many times in advance to...
