Abstract
The invention discloses a method for generating dynamic data of a dynamic seat based on video processing. The method comprises the following steps of identifying an image of a film video, and selecting a plurality of feature points of any feature objects on the image as required; tracking the position change of all the feature points through a video processing algorithm by utilizing a computer; calculating and obtaining a movement parameter and a movement trail of a virtual camera through video processing algorithm according to the position change of the feature points; calculating and obtaining the practical movement trails and movement parameters of the feature objects through the video processing algorithm according to the movement parameter and the move trail of the virtual camera; generating the dynamic data of the dynamic seat according to the practical movement trails and the movement parameters of the feature objects. By means of the method for generating dynamic data of the dynamic seat based on video processing, automatic generation of the dynamic data is almost achieved, generation efficiency of the dynamic data is greatly improved, accuracy of the dynamic data obtained through the method is obviously improved, and the method can eliminate the hysteretic property of the dynamic data.
Description
Technical field
The present invention relates to multidimensional seat technical field, particularly a kind of method that generates the dynamic data of multidimensional seat based on Video processing.
Background technology
As everyone knows, along with the development of 3D film, the application of multidimensional seat in 3D movie theatre is more and more extensive.In the time of film projection, multidimensional seat can be made exercises along with the variation of the story of a play or opera, thereby brings spectators sensation on the spot in person.This advantage of multidimensional seat has obtained numerous moviegoers' favor.
Each film is before 3D movie theatre is shown, and technician need to obtain the multidimensional seat exercise data of this film, and sends it to movie theater.In the time that film starts to show, multidimensional seat exercise data is sent to each multidimensional seat by movie theater, and multidimensional seat is made corresponding action according to its exercise data.The film that a preparation is shown, the multidimensional seat exercise data how obtaining correspondingly becomes technician's problem demanding prompt solution.
In prior art, comprise manual method and rocking bar method etc. for obtaining the method for multidimensional seat exercise data.The principle that manual method generates dynamic data is, allows technician watch to make but the film not yet shown at 3D movie theatre, and along with the variation of the story of a play or opera, technician inputs multidimensional seat exercise data according to the inner experience of self and impression by computer program.The principle that rocking bar method generates dynamic data is, the film that allows technician watch to make but not yet show at 3D movie theatre, watch technician in process to hold a rocking bar, along with the variation of the story of a play or opera, technician removes to shake the rocking bar in its hand according to the inner experience of self and impression, utilize with it measurement mechanism to measure the movement locus of rocking bar, then according to the trace generator multidimensional seat exercise data of rocking bar simultaneously.
There is following shortcoming and defect in above-mentioned manual method and rocking bar method:
(1) need to expend a large amount of manpowers, efficiency is lower, and cost is higher;
(2) different technician is in the face of the Same Scene of film, and its inner experience and impression exist very large individual difference, and therefore the accuracy of said method is lower;
(3) technician just can react after seeing the scene of the film of showing, then just can remove to shake rocking bar, need certain reaction time from the scene of seeing film to shake rocking bar, therefore said method generates dynamic data and has hysteresis quality, thereby easily affects multidimensional seat in actual applications and bring spectators' sensory effect;
(4) for the even identical motion of some similarity height, the generative process of its dynamic data cannot effectively copy or repeat, therefore, for identical motion, the dynamic data deficiency consistance that said method generates, and then the effect that causes multidimensional seat in practical application to bring spectators is also lack of consistency.
Summary of the invention
The object of the invention is the above-mentioned defect for prior art, a kind of method that generates the dynamic data of multidimensional seat based on Video processing is provided.
The method of the dynamic data based on Video processing generation multidimensional seat provided by the invention comprises the steps:
Identify the image of film video, and on this image, choose as required multiple unique points of arbitrary characteristics thing;
Along with the broadcasting of film video, utilize computing machine to follow the tracks of the change in location of all unique points by video processnig algorithms;
According to the change in location of all unique points, calculate kinematic parameter and the movement locus of virtual video camera by video processnig algorithms;
According to the kinematic parameter of virtual video camera and movement locus, calculate actual motion track and the kinematic parameter of characteristic body by video processnig algorithms;
According to the dynamic data of the actual motion track of characteristic body and kinematic parameter generation multidimensional seat.
Preferably, the dynamic data that the dynamic data of described multidimensional seat are Three Degree Of Freedom.
The present invention has following beneficial effect:
(1) method of the present invention does not need to expend a large amount of manpowers, has almost realized the robotization that generates dynamic data, has greatly improved the formation efficiency of dynamic data, has obviously reduced the cost of manufacture of action effect;
(2) method of the present invention has been eliminated the individual difference of technician's inner experience and impression, and the accuracy of the dynamic data of acquisition obviously improves;
(3) method of the present invention can be eliminated and generate the hysteresis quality of dynamic data, is conducive to improve multidimensional seat and brings spectators' sensory effect;
(4) method of the present invention is applicable to different scenes, such as blast, earthquake, gunslinging, the scene such as dizzy, terrified, and the dynamic data of the Same Scene obtaining can be reused in different films.
