Abstract
The invention discloses a method and device for truly obtaining movement data of a dynamic cinema and synchronizing photographing, three-dimensional production and later-stage editing. According to the method and device, a binary data computer file which records a coded representation mode of a lens space posture and is converted into a sample of a wav audio format sample sequence of a single track is defined and described; the binary data computer file is defined by a sample sequence data structure compatible with different platform movement signals.
Description
Technical field
The present invention relates to the method and apparatus that a kind of dynamic cinema generates exercise data, belong to the broadcasting and TV applied technical fields such as three-dimensional film, simulation film.
Background technology
Dynamic cinema is very universal at present, uses motion platform structure more widely to have Three-degree-of-freedom motion platform and 6-dof motion platform.3-dimensional freedom platform is taking CN201394351y Three degree-of-freedom motor servo and the dynamic seat of US Patent No. 7934773 B2 Three Degree Of Freedoms etc. as representative, six degree of freedom platform adopts parallel institution STEWART platform more, as US Patent No. 6113500 etc., other structures ZL94206426.7 etc.;
The disconnections such as the action data that dynamic cinema is used and the shooting of film, d-making, later stage compilation, employing later stage manual simulation's mode, action effect does not generally have authenticity, weak effect, the production of dynamic cinema exercise data becomes a great problem.Do not have at present a kind ofly can be applicable to different film formats and substance film and can and convert the method that different platform adapts to the data format file of all dynamic cinemas to later stage software editing; There is no complete description and define the action data computer documents of a set of compatible different platform motor message yet.
Summary of the invention
A kind of shooting, d-making and later stage compilation synchronously and truly obtain the method and apparatus of dynamic cinema exercise data; Its definition and described a kind of coded representation mode that records lens space attitude and number converted the binary data computer documents of the sample of monaural wav audio format sample sequence to; And defined by the sample sequence data structure of a set of compatible different platform motor message.
The video camera of different-format different content film is modeled to " spectators' eyes " by the present invention, by the attitude of camera lens both " spectators' eyes " thus attitude change and be converted to platform stance and change and feed back to spectators and produce real motion impression.100 is the manufacturing process of film, the 200 projection processes that are movie theatre; In the shooting process of film, by the position transducer being arranged on video camera 101, the sensor image data 102 collecting is stored; The film lens data of simultaneously making by three-dimensional software 103 is derived virtual video camera lens data 104 by software; Because the content made from three-dimensional software in film shooting process will just can become final film through the montage of later stage compilation software 107, in order to ensure synchronizeing and the editor of compatible later stage software of lens data file 105 and content, the present invention is converted into amount of audio data wav file layout by lens data 105 by lens data file conversion wav audio format module 106, and later stage compilation software 107 can and well ensure the synchronism of camera lens file and substance film without any processing editor lens data file like this; The camera lens file of the wav form after post-processed, by data smoothing and optimization module 109 and the final formation of artificial data optimization 110 and the synchronous platform exercise data file 111 of issuing of film; Platform exercise data file 111 brings real dynamic effect finally to spectators 203 by the control of platform and software for environmental control and 201 pairs of motion platforms 202 of device.
Substance film is in conjunction with forming real dynamic cinema effect.
Referring to Fig. 2, is frame information and x, y, z, α, β, six groups of data of γ according to the definition of world coordinates and camera coordinates system by lens data document definition.Lens data initial point is video camera photocentre, the x of x axle and y axle and image, and y axle is parallel, and z axle is camera optical axis, and it is vertical with the plane of delineation, uses respectively α, beta, gamma to represent the angle of three axles, the camera coordinate system of formation.In the shooting process of film, can obtain camera lens data by the sensor that is arranged on video camera and take on frame, d-making part also can be obtained by the export function of three-dimensional software the lens data of virtual video camera camera lens simultaneously.
Refer to Fig. 4, motor message file, the first behavior file of file is described, and file is described and is mainly played annotation effect, and the publisher of file, author, user can annotate description document relevant information.The second row plays the end of file, be defined as frame information heel data 1, data 2, data 3, data 4, data 5, data 6 six rent data, digital camera uses motion platform structure more widely to have Three-degree-of-freedom motion platform and 6-dof motion platform at present.3-dimensional freedom platform is taking CN201394351y Three degree-of-freedom motor servo and the dynamic seat of US Patent No. 7934773 B2 Three Degree Of Freedoms etc. as representative, six degree of freedom platform adopts parallel institution STEWART platform more, as US Patent No. 6113500 etc., other structures have ZL94206426.7 etc.The motion platform of said structure is Three Degree Of Freedom, six degree of freedom or other structures no matter, and all, taking cylinder length variations as basis, its movement locus all can be described by the cylinder length variations of platform the motion of platform.For the compatible Three Degree Of Freedom of data layout while of unified different platform and the exercise data of six degree of freedom platform, motor message file consolidation is set to 1-6 group data, if all the other rear three groups of data of Three Degree Of Freedom are that alternative data also can be for empty.Specifically describe as follows: if movie is to time N frame data, 1-6 group platform cylinder long data when platform and software for environmental control and device issue N frame film, platform is carried out corresponding length according to cylinder long data, change repetitive cycling said process according to the frame number of film, make the movement effects that platform forms and substance film coordinates.
