Virtual video camera planning and distributing method and system

Abstract

The invention discloses a planning layout method for a virtual camera, which comprises the following steps that: environmental data of a three-dimensional scene to be shot and semantic restraints of a target picture are input; the semantic restraints of the target picture in the step are classified into a space semantic restraint and a screen semantic restraint; the space semantic restraint is made a space semantic computation to evaluate a space area, and a predicate formula that the space semantic restraint corresponds to is true when a virtual camera or a target point is in the space area; the output result of the space semantic computation is read to make a screen semantic computation, and a group of attribute values of the virtual camera which meet all the screen semantic restraints are obtained through a method for optimized search; and the position of a virtual camera is output. The method can automatically evaluate the position parameters of the virtual camera according to the picture content which is expected to obtain and meets the different requirements.

Description

technical field [0001] The present invention relates to the field of automatic layout technology, in particular to simulating the shooting process of people and objects in a virtual three-dimensional scene, and automatically calculating the position parameters of the virtual camera according to the expected content of the screen that meets different requirements, that is, virtual camera planning Layout method and system. Background technique [0002] Virtual camera planning technology has developed rapidly in the past ten years, and it has penetrated into every corner of people's lives. Compared with the traditional camera, the existing virtual camera planning technology can already liberate the virtual camera from the fixed workbench, so that the placement and movement of the virtual camera are no longer subject to any restrictions, and have a more powerful expressive ability, based on Therefore, how to carry out virtual camera planning (Camera Planning, CP), perform virtu...

Problems solved by technology

[0011] Although the methods and systems in the prior art have explored and researched camera planning from different angles, involving games, teaching, animation production, etc., the prior art has the following defects: ① Cannot describe user needs accurately and in detail , the generated picture does not meet people's expectations; ②The situation that can be handled is too simple, not suitable for large-scale projects; ③The processing speed and precision are not enough, and satisfactory results cannot be obtained within a reasonable time
