Embodiment Construction

[0032] The method for setting shooting parameters provided by the present invention is to analyze and deduce the three-dimensional software Maya camera and the stereo camera, and then obtain the film width, lens focal length, camera spacing, imaging plane distance, object distance, The horizontal resolution of the picture, and the relationship between the screen width, viewing distance, and screen aberration of the theater during the screening form a formula, which is verified by the actual shooting picture and the Maya camera rendering picture data. The theoretical derivation process of the formula will be introduced in detail below.

[0033] figure 1 is a schematic diagram of an imaging system for a 3D movie according to an embodiment of the present invention. Such as figure 1 As shown, the distance between the two cameras is T, the horizontal width of the imaging unit (film, CMOS or CCD, hereinafter referred to as the film) is w, and the distance between the intersection ...

Abstract

The invention discloses a setting method and system for shooting parameter, in the invention, firstly determining an effect parameter which reflects the three-dimensional effect and / or the watch effect of a 3D-film, then inputting the determined effect parameter and other known shooting parameters through the input module, calculating the adjustable parameter from the formulas stored in the storage module, setting the shooting system according to the adjustable parameter calculated by the setting module to achieve the expected three-dimensional effect and / or watch effect. The invention is capable of roughly predicting the ultimate watch effect in the theater as early as the film is shot, or calculating out the adjustable shooting parameters used in real shooting based on the expectant three-dimensional effect of film, comprising a focal length, an imaging distance, an object distance etc, and ensuring the stereo effect of the final show.

Description

technical field [0001] The invention relates to digital film technology, in particular to a shooting parameter setting method and system. Background technique [0002] Three-dimensional film compares with planar film, because lifelike, lifelike, can give people powerful visual impact, thereby has broad prospect. However, at present, when shooting stereoscopic films, the values ​​of shooting parameters, such as object distance and camera parameters in the real scene, are mostly adjusted by the photographer according to his own experience or judgment, or by selecting a pre-provided The shooting mode is set automatically, so that the filmed film does not take into account the viewer's parallax angle, which will make the viewer feel uncomfortable during the final screening. In addition, in order to achieve the expected three-dimensional effect in the final screening, the shooting parameters must be continuously adjusted. This process is very complicated, which will cause a lot ...
