To obtain other drawings based on these drawings.
Fig. 1 is system module figure of the invention
Specific embodiment
To keep the purposes, technical schemes and advantages of the embodiment of the present invention clearer, below with reference to the embodiment of the present invention
In attached drawing, technical solution in the embodiment of the present invention carries out clear and complete description:
A kind of musical instrument auxiliary based on AR augmented reality is played as shown in Figure 1: and experiencing system is played by association, mainly includes image
Acquisition unit, in use, the unit acquire the video image that currently used person holds musical instrument in real time, while in order to subsequent
Video identification, the video image also includes gripping finger nail.
Image analyzing unit analyzes the image of current musical instrument, identifies the profile and operating area of current musical instrument, and identification is fixed
The string or key of position musical instrument, that is, divide specific image-region, as subsequent algorithm foundation.In subsequent operational process
In, image analyzing unit string, profile and operating area described in work shadow always.
Second storage unit, the unit store minimum performance unit syllable and the corresponding hand of note in music score and a collection of impressions of seals by famous seal
The position of finger movement and the virtual animated element of auxiliary instrument operation, such as when a performance unit series of sound is needed by next string,
Auxiliary instrument is needed when running full bow on a string simultaneously, and virtual animation display indicates the animated element of index finger, such as with number
Word (for example setting label 1 for index finger) or the figure for being different from other fingers, the animated element moved downward, while in setting
Fortune bow angular regions when one string show the animation of auxiliary instrument figure and the traffic direction with special angle.Meanwhile it can also
To provide the information such as corresponding text prompt or voice prompting.
In use, user is started by operating unit control system, selects current performance song；Processing unit
According to the profile and operating area of the current musical instrument, string, key or the strike region of the musical instrument after positioning, described
It is shown on display unit.
The animated element display area delimited on the display region.Meanwhile processing unit transfers the second storage unit
In corresponding music score and corresponding push action and auxiliary instrument operation virtual animated element, it is aobvious in the animated element
Show in region and shows；User guides according to the virtual animated element, completes the performance of current melody, i.e. learning experience mistake
Journey.
In order to expand corresponding function, in playing procedure, the processing unit is drilled by sound collection unit acquisition
The audio of song is played, analysis obtains audio curve, compares, provide currently used with the audio curve stored in the second storage unit
The scoring of person's performance level.
As optional embodiment, sound collection unit can be used the earpiece of smart phone, or use integrate it is sound
Sound acquires the AR glasses of equipment or accesses existing equipment using Wireless/wired sound collection equipment.Scoring algorithm can use
The similar algorithm such as singing marking algorithm in existing similar KTV can be realized, the purpose in encouragement, and acquisition key sound is
It can.
Correspondingly, may also set up the evaluation criterion of different difficulty, for the user of different levels, different stage is set
Algorithm increases the sustainability operation of system.
In order to utilize the technical equipment of existing maturation as far as possible, increases device integration, reduce user and wear
Number of articles, as preferred embodiment, the image acquisition units, image analyzing unit, operating unit and processing are single
Member and display unit are integrated on intelligent terminal or intelligent helmet/glasses.As the core of system, replacement operation core and phase
The scheme of this patent proposition can be realized in the algorithm answered.
Whether the operation in order to identify currently used person is correct, as preferred embodiment, the processing list
The image that member is collected by image acquisition units tracks auxiliary instrument running track and the position of nail of currently used person,
The position for especially pressing the nail of string is compared with the virtual animated element stored in second storage unit.
More feasible embodiment, when the auxiliary instrument running track and nail position that determine user and virtual animation
When element is close in threshold range, in display interface, it can be understood as virtual animated element and finger nail appear in phase substantially
As region, can significantly be overlapped, that is, can determine that currently used person according to system suggestion, complete current note or syllable
Correct performance, and provide the prompt correctly played.
Herein, the double hit prompt mechanism in other game can be used for reference, when being correctly completed the performance of a note
The prompt for providing+1 provides the prompt of+N when being continuously correctly completed performance, and provide corresponding encouragement word or class
Like prompt.
In order to such that long-range symphony association plays, as preferred embodiment, system by network cooperation
Including the third storage unit integrated in remote server and server, in the server collection system scoring of registration user and
Melody generates the hierarchal grouping for being directed to each musical instrument according to musical instrument type, and composition is stored in the third storage unit and is closed
That plays music bent each musical instrument divides music score.By grade classification system user is played, can be avoided during association plays because of member's water
Adjustment is different excessive, causes He Zou result undesirable.Meanwhile association can be opened again more than certain grade and played.
Registration user downloads institute by the communication unit in respective system according to respective musical instrument type and grade in system
That states divides music score, and the performance for dividing music score is assisted or voluntarily completed by system；Divide the playing procedure of musical instrument by the sound collection
Unit acquisition is transmitted to remote server by the playing procedure；Server collects the whole performances for instrumental ensembling melody
Process is synthetically generated (instrumental) ensemble melody in distributed workstation, stores and is back to and instrumental ensembles the player that melody divides music score；Storage
(instrumental) ensemble melody disclosed into system.
Further, it is contemplated that the color of auxiliary instrument is closer to musical instrument body color, leads to recognizer mistake
In complexity, as preferred embodiment, the string and auxiliary instrument surface are equipped with the equidistant mark that axis extends.It can
Spaced black and white color lump is selected, is identified convenient for algorithm, reduces the identification runing time of algorithm.
Likewise, user, which holds finger nail, is respectively equipped with the distinctive mark mutually distinguished.Such as to respectively correspond 1/2/
1/2/3/4 number is respectively set in index finger, middle finger, the third finger and the little finger of toe of 3/4 string, identifies convenient for computer.
As preferred embodiment, the distinctive mark is integrated in position corresponding with nail on an auxiliary glove.
In order to the various stimulations of user and guidance, as preferred embodiment, the processing unit
When providing the corresponding virtual animated element of finger according to current note, the electro photoluminescence patch for controlling corresponding finger is powered.
Above the tight boom plate of musical instrument, it is equipped with the fixture of fixed intelligent terminal close to the position of micro actuator, facilitates fixed mobile phone etc.
Equipment.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
