Embodiment Construction

[0057] In order to make the purpose, technical solution and advantages of the present invention clearer, a virtual camera planning and layout method and system of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0058] The essence of the problems existing in the prior art is that there is no effective solution to the virtual camera planning layout (Virtual Camera Planning, VCP). Based on this, the present invention constructs a heuristic knowledge base with professional knowledge of photographers, proposes a virtual camera planning method and system based on constraint satisfaction, and provides a new set of production evaluation criteria to solve computer production problems. The virtual camera planning layout (VCP) problem in medium.

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...
