S1, the voice that apparatus for establishing explanation needs, corresponding captions and Voice command animation curve, and determine according to segmentation the parts three-dimensional body that converting equipment angle corresponding to every section of voice and needs highlight.
In time taking one section of equipment explanation word, first equipment is explained word and be off mark with fullstop, will decompose in full, resolve into some segment words, every segment word stores respectively as the unit of Subtitle Demonstration; Then according to normal bright read rate, for every segment word is dubbed, every dubbing of segment word is stored respectively; Finally Word message is merged with corresponding voice messaging, set up voice segments and captions configuration file.As shown in Figure 2, in voice segments and captions configuration file, a line represents the corresponding relation of one section of voice and captions, is separated in phonetic storage path and corresponding captions using " _ & _ " as separator.Every section of phonetic storage file can be found by phonetic storage path.
Substation equipment maintenance and repair simulation training system adopts the exploitation of unity development environment, animation curve is set up by the Animation Editors of unity development environment, in Animation Editors, arbitrary curve can be set up for the mode of certain parameter value insertion key frame, and be stored as animation form.When animation starts to play, along with the passing of x time shaft, y-axis value can change along with the change of curve.In embodiment provided by the present invention, the basis of animation curve builds Voice command animation curve.When building Voice command animation curve, use a controling parameters Controller as y-axis, along with the passing of x time shaft, y-axis value can change along with the change of curve.Controller parameter is as a controling parameters, and when x time shaft constantly changes along with passage of time, Controller parameter constantly triggers corresponding voice and captions.Controller parameter determines the crucial frame number of animation needing to set up according to the information number in voice segments and captions configuration file.When will control n section speech play time, then need set up n+2 animation key frame for Controller parameter.Wherein the 1st frame is start frame, and the n-th+2 frame is end frame, and n middle animation key frame is the trigger frame of n section voice.Do not need human intervention, improve the accuracy of triggering, reduce the probability that mistake occurs.
As shown in Figure 3, the time location of 0.00 second is set up the 1st frame as start frame, and Controller parameter value is less than 0.On the time shaft appropriate location being greater than 0.0 second, set up the 2nd frame, arranging Controller parameter value is 0, starts the trigger point of playing as broadcasting the 1st section of voice and captions; In embodiment provided by the present invention, time shaft appropriate location time of reserving when being the initialization of substation equipment maintenance and repair simulation training system, read in the voice and corresponding captions that have recorded, and make the time that it is associated with Voice command animation curve.On the time shaft position being greater than the 1st section of voice length, set up the 3rd frame, putting Controller parameter value is 1, starts the trigger point of playing as the 2nd section of voice and captions; Now, dead time and the 1st section of voice recording time sum that the time that the time shaft position of the 1st section of voice length represents is every segment in voice recording process is greater than.By that analogy, on the time shaft position being greater than (n-1)th section of voice length, set up the (n+1)th frame, arranging Controller parameter value is n-1, starts the trigger point of playing as n-th section of voice and captions.On the time shaft appropriate location being greater than n-th section of voice length, set up the n-th+2 frame, arranging Controller parameter value is n, as end frame.Be as the criterion with m frame (any frame), between m frame and m-1 frame, the linear change of Controller parameter value; Between m frame and m+1 frame, the same linear change of Controller parameter value, this linear change ensures that the voice between every two frames are all at the uniform velocity play, the voice on the corresponding time location of each Controller parameter value and caption information.One section of corresponding Voice command animation curve of equipment explanation word, a Voice command animation curve passes through broadcasting and the switching of Controller state modulator multistage voice and corresponding captions.
Meanwhile, determine according to segmentation the parts three-dimensional body that converting equipment angle corresponding to every section of voice and needs highlight.In embodiment provided by the present invention, when converting equipment being explained by voice, a virtual video camera is set in substation equipment maintenance and repair simulation training system, according to the difference of voice content, play the different angles of converting equipment by the change in virtual video camera view position and direction, the parts three-dimensional body explained by voice content emphasis is highlighted by color change.Determine that the parts three-dimensional body that converting equipment angle corresponding to every section of voice and needs highlight specifically comprises the steps: according to segmentation
S11, sets up a virtual video camera, can all angles of converting equipment involved by playback equipment explanation word according to the change in view position and direction.
S12, for the content of every section of speech sound eeplaining, sets up view position and the direction of the virtual video camera of its correspondence, and determines the parts three-dimensional body that needs to highlight.
In embodiment provided by the present invention, the view position of each section of all corresponding virtual video camera of voice and direction, the view position of virtual video camera and direction are certain points in the three-dimensional coordinate at the virtual video camera place when virtual video camera can show certain angle of converting equipment.For the content of every section of speech sound eeplaining, determine that screen needs the angle of the converting equipment of display, three-dimensional coordinate position corresponding for certain point in the three-dimensional coordinate at virtual video camera place during this angle of display is saved in array DirectionAndGlitterGRP as the view position of the virtual video camera of correspondence and direction, uses when converting equipment being explained so that follow-up.
In addition, for the content of every section of speech sound eeplaining, determine the parts three-dimensional body relevant to content, be saved in array DirectionAndGlitterGRP, when converting equipment being explained so that follow-up, in order to the specific aim of outstanding explanation, improve authenticity and the explanation efficiency of explanation, use when it is highlighted.
S13, the priming color of the parts three-dimensional body that the parts three-dimensional body highlight the view position of virtual video camera corresponding for every section of voice and direction, needs and needs highlight is stored in array DirectionAndGlitterGRP.
S2, extracts the priming color needing the parts three-dimensional body highlighted, and reads in the voice of recording and corresponding captions during the initialization of substation equipment maintenance and repair simulation training system.
During the initialization of substation equipment maintenance and repair simulation training system, the priming color of the parts three-dimensional body that the needs extracting storage from array DirectionAndGlitterGRP highlight, for after playing certain section of voice, recover parts three-dimensional body to original state.
In addition, also need to read in the voice of recording and corresponding captions when the initialization of substation equipment maintenance and repair simulation training system, be associated with Voice command animation curve so that follow-up, while Voice command animation curve is play, play corresponding voice and corresponding captions.As shown in Figure 4, when the initialization of substation equipment maintenance and repair simulation training system, utilize the mode of data stream, open outside voice segments and captions configuration file, read the internal information of voice segments and captions configuration file line by line.By each line number according to this " _ & _ " separate for separator, be stored in an interim array str, and every line number group added in a temporary container arrlist.Until the content in voice segments and captions configuration file is all read complete, close data stream, by the content assignment in temporary container arrlist to dataArray container.
From each element of dataArray container, extract phonetic storage path, find voice messaging according to phonetic storage path, and be stored in audioArray container.
S3, voice and corresponding captions are associated with Voice command animation curve, play Voice command animation curve, go forward side by side lang sound and captions are play and hand-off process, show corresponding converting equipment angle according to speech play content simultaneously, and related components three-dimensional body is highlighted.
After the voice reading in recording and corresponding captions, by the Controller parameter of Voice command animation curve, voice and corresponding captions are associated with Voice command animation curve.When one section of equipment explanation word of substation equipment maintenance and repair simulation training system can be broken down into n section speech play, corresponding Controller parameter establishes n+2 animation key frame, the corresponding Controller parameter value of each animation key frame.Wherein the 1st frame is start frame, n-th+2 frame is end frame, n middle animation key frame is the trigger frame of n section voice, the trigger point of the corresponding one section of voice of each trigger frame and one section of captions, As time goes on, Controller parameter increases gradually, when the m animation key frame as trigger frame that arrival Controller parameter is corresponding, from audioArray container and dataArray container, extract the m-1 section captions of m-1 section voice and its correspondence respectively, play.Now, Controller parameter reaches particular parameter value m-2, in embodiment provided by the present invention, particular parameter value be more than or equal to zero integer.Meanwhile, from array DirectionAndGlitterGRP, extract the parts three-dimensional body that the view position of virtual video camera corresponding to m-1 section voice and direction and needs highlight.And start the coordinate of virtual video camera and direction transformation process makes its broadcasting along with voice move in three dimensions, start to highlight to specify the process of parts three-dimensional body simultaneously.
As shown in Figure 5, in three dimensions, the object principle that moves to b point from a point is as follows:
In three dimensions, the vector of some a is Ia, and the vector of some b is Ib, and object, for moving to b point from a point, need obtain the vectorial Ic of a point to b point.Vector Ia and vectorial Ib just can obtain Ic:Ic=Ib-Ia by subtraction.
The direction of vector Ic is exactly the direction of object of which movement, and its mould is exactly the distance of object of which movement.
In order to realize the authenticity emulated, understand converting equipment better, present converting equipment model mainly adopts three-dimensional picture, along with the voice recorded ceaselessly are play, view position and the direction of virtual video camera are ceaselessly moved, to realize the different angles showing converting equipment three-dimensional picture on screen.When broadcasting m-1 section voice, view position and the direction of virtual video camera corresponding to m-1 section voice is extracted from array DirectionAndGlitterGRP, then according in three dimensions, the vectorial Ia1 of the some a1 at the current place of virtual video camera, and the vectorial Ib1 of the view position of virtual video camera corresponding to m-1 section voice and the some b1 (impact point) representated by direction, if obtain virtual video camera to want to show direction and the distance that converting equipment angle corresponding to current speech need movement.Wherein direction is the direction of vectorial Ic1: Ic1=Ib1-Ia1.Its mould is exactly the distance of virtual video camera motion.Along with virtual video camera moves to impact point, the mould of Ic1 reduces gradually, when its value is not more than 0.005, be considered as this virtual video camera and arrive assigned address, virtual video camera stops mobile, screen shows virtual video camera when impact point b1, the angle of the converting equipment that virtual video camera is irradiated to.Make the angle of the converting equipment corresponding to voice, captions and voice content consistent, improve the authenticity of emulation, converting equipment can be understood more fully.
In addition, when broadcasting m-1 section voice, parts three-dimensional body (target three-dimensional body) information that needs corresponding to m-1 section voice highlight is extracted from array DirectionAndGlitterGRP, in embodiment provided by the present invention, target three-dimensional body highlight effect show as color present gradual change flicker effect.Specifically comprise the steps:
Between the priming color a of the target three-dimensional body first extracted when the initialization of substation equipment maintenance and repair simulation training system and the color b of final display, setting interpolation t, a t change between 0 to 1.A is returned when t is 0; Return b when t is 1.Then a Sin sinusoidal wave function is set, using the value of the rreturn value of Sin sinusoidal wave function as interpolation t, Sin sinusoidal wave function is along with time fluctuation, the color of target three-dimensional body turns to color b by color a, realize color gradient flicker effect, make saying in solution preocess, the parts three-dimensional body of voice design can highlight, concentrate attention rate, the effect of explanation can be improved.After speech play, the parts three-dimensional body relevant to this section of voice recovers priming color.
As time goes on, the parameter value of Controller parameter increases gradually, arrive the trigger frame of high one deck gradually, from audioArray container and dataArray container, extract the captions of voice and its correspondence by voice and captions storage order one by one, it is play.Along with the broadcasting of voice and captions, virtual video camera rotates converting equipment visual angle corresponding to display gradually, and highlights relevant parts three-dimensional body, improves authenticity and the specific aim of emulation, can understand converting equipment more fully.
When substation equipment maintenance and repair simulation training system starts to explain converting equipment, Voice command animation curve starts to play, when Controller parameter value is 0, the equipment of the correspondence explanation first paragraph voice of word and captions corresponding to first paragraph voice trigger by trigger frame, from audioArray container and dataArray container, extract the first paragraph captions of first paragraph voice and its correspondence respectively, play.Meanwhile, from array DirectionAndGlitterGRP, extract the parts three-dimensional body that the view position of virtual video camera corresponding to first paragraph voice and direction and needs highlight.And start the coordinate of virtual video camera and direction transformation process makes its broadcasting along with voice move in three dimensions, start to highlight to specify the process of parts three-dimensional body simultaneously.Make the converting equipment angle that on screen, display is relevant to voice, and relevant parts three-dimensional body is highlighted.As time goes on, Controller parameter value is increasing gradually, the captions of triggering voice and its correspondence successively, until all voice in audioArray container and dataArray container and captions are all finished, Controller parameter value is n, and Voice command animation curve arrives end frame, explanation terminates, virtual video camera gets back to initial position, and the initial angle of display converting equipment, all parts three-dimensional bodies return to priming color.One section of corresponding Voice command animation curve of equipment explanation word, a Voice command animation curve passes through broadcasting and the switching of Controller state modulator multistage voice and corresponding captions.In whole playing process, do not need human intervention, improve the accuracy of triggering, reduce the probability that mistake occurs.
