Detailed Description
In this embodiment, the vehicle-mounted music playing method may be applied to the vehicle-mounted system shown in fig. 1. Referring to fig. 1, the in-vehicle system includes a control module, an emotion recognition module, a storage module, a communication module, a sensing module, and a music playing module. Wherein the control module is a device having data processing and control functions, for example, an ECU (electronic control unit) on board can be used as the control module; the emotion recognition module can recognize emotion types of the personnel on the vehicle by collecting facial expression, limb actions or breathing, heartbeat and other information of the personnel on the vehicle; the storage module can establish a song library, and music information is stored in the song library; the communication module can be connected with the Internet through a wireless communication protocol, accesses the music server through the Internet and downloads the needed music information; the sensing module comprises sensors arranged at the positions of an engine, a steering wheel, an accelerator pedal, a brake pedal, wheels and the like on the automobile, and driving parameters such as the rotation speed of the engine, the steering amplitude of the steering wheel, the current speed, the current acceleration and the like can be acquired through the sensors; the music playing module comprises devices such as a power amplifier, a loudspeaker and the like, can receive the music information output by the control module, and plays corresponding sound in the automobile cabin.
In this embodiment, referring to fig. 2, the vehicle-mounted music playing method includes the steps of:
s1, identifying first emotion information of personnel on a vehicle;
s2, acquiring a first music piece according to the first emotion information;
s3, playing the first music piece;
s4, detecting emotion changes of the personnel on the vehicle in the playing process of the first music piece, and identifying second emotion information of the personnel on the vehicle;
s5, acquiring a second music piece according to the second emotion information;
s6, splicing the first music piece and the second music piece to obtain spliced music;
s7, synchronously switching the playing of the first music piece to the playing of spliced music.
Steps S1-S7 are performed by the control module. When the control module performs some of the steps, it may call the emotion recognition module of fig. 1 or the like to acquire the required data or output the data to these components.
In this embodiment, steps S1 to S7 will be described with the driver as an example of the person on the vehicle.
In step S1, the control module triggers the emotion recognition module to work, and performs emotion recognition on the driver to obtain first emotion information. The first emotion information indicates the emotion type of the driver, such as calm, anger, low, happy, etc., when the control module performs step S1. The emotion recognition module sends the recognized first emotion information to the control module.
In step S2, the control module searches for corresponding music from a song library locally stored in the storage module shown in fig. 1 or from a cloud server through the communication module according to the first emotion information. The search conditions of the control module are: the music found matches the first mood information, i.e. can have an enhancing effect on the positive mood of the first mood information type the driver has, or can have a relieving effect on the negative mood of the first mood information type the driver has. For example, if the first mood information indicates a happy type of mood, finding music of the happy type can have an enhancing effect on this, and the music of the happy type is matched with the first mood information; if the first mood information indicates a low-lying type of mood, finding a light-fast type of music can have a relieving effect on this, and the light-fast type of music is matched with the first mood information.
In step S2, when the control module finds out the music information matching with the first emotion information from the local song library or cloud, the music information is read or downloaded to the control module to obtain the first music piece.
In step S3, the control module decodes the first music piece, thereby obtaining audio waveform information. The control module sends the audio waveform information to the music playing module to trigger the music playing module to play corresponding sound, so that the first music piece is played.
And when the step S3 is executed, the control module synchronously executes the step S4, and invokes the emotion recognition module to continuously recognize the emotion of the driver so as to obtain emotion information detected in real time. When the emotion information different from the first emotion information is detected, the emotion of the person on the vehicle is judged to be changed, and new emotion information is obtained, wherein the new emotion information is the second emotion information. The emotion recognition module sends the second emotion information to the control module.
When executing step S5, the same principle as that of step S2, the control module searches the music information matched with the second emotion information from the local song library or cloud, and reads or downloads the music information to the control module to obtain the second music piece.
In step S6, the control module performs a stitching process on the first music piece obtained in step S2 and the second music piece obtained in step S5 to obtain stitched music.
When executing step S7, the same principle as that of step S3, the control module stops playing the first music piece and starts playing the spliced music, thereby switching the first music piece to the spliced music.
By executing the steps S1-S7, when the first emotion information and the second emotion information, that is, the emotion of the person on the vehicle changes, can be detected, spliced music is played, wherein the spliced music is formed by splicing a first music piece and a second music piece which are respectively matched with the first emotion information and the second emotion information (wherein the spliced music is also sometimes called as 'mixed connection', 'mixed shearing', 'merging', 'synthesizing', and the like; in addition, the spliced music is played in a song mode, after the part corresponding to the first music piece in the spliced music is played, the part corresponding to the second music piece in the spliced music can be seamlessly switched to play, and the phenomena of music pause and the like in the song cutting process are avoided, so that the music playing device has a more natural playing effect, the effect of enhancing or relieving emotion changes, the emotion changes of people on a vehicle can be approached, and a good emotion improving effect is facilitated.
In this embodiment, when performing step S5, that is, the step of acquiring the second music piece according to the second emotion information, the following steps may be specifically performed:
s501, according to the second emotion information, searching a plurality of matched candidate music pieces from a music library;
s502, setting music splicing conditions;
s503, detecting whether the music splicing condition is met or not by the currently played part in the first music piece and each candidate music piece respectively;
s504, when the fact that the candidate music pieces meet the music splicing conditions is detected, the candidate music pieces meeting the music splicing conditions are used as second music pieces.
S505, when any candidate music piece is not detected to meet the music stitching condition, selecting one candidate music piece from all candidate music pieces as a second music piece.
In this embodiment, the principle of steps S501-S505 is shown in fig. 3.
Referring to fig. 3, in step S501, the searched plurality of candidate music pieces and the second emotion information, that is, by playing the candidate music pieces, can strengthen the positive emotion represented by the second emotion information of the person on the vehicle or alleviate the negative emotion represented by the second emotion information of the person on the vehicle.
In step S502, the control module may set a music stitching condition according to the rule of "music burn-in". For example, the music stitching condition may specifically include: and in the spliced two music fragments, the last part of the former music fragment is similar to the tune of the beginning part of the latter music fragment, the song style is similar, or the lyrics escort is similar, etc.
In step S503, the control module detects the currently played portion of the first music piece and each candidate music piece respectively. For example, for any one of the candidate pieces of music, it is detected whether or not the start portion of the candidate piece of music satisfies the "music splice condition of" tune similar, song style similar, lyrics rhyme, or the like "with the currently played portion (at the position played when step S5 is performed) in the first piece of music; if the candidate musical piece satisfies the music splicing condition, the candidate musical piece is determined as the second musical piece, otherwise, the candidate musical piece is not determined as the second musical piece, and the judgment of other candidate musical pieces is continued.
Steps S503-S504 are executed, and all the candidate music pieces are traversed, and the execution results of steps S503-S504 include: (1) Only one candidate music piece meeting the music splicing condition is detected; (2) Detecting a plurality of candidate music pieces meeting the music splicing conditions; (4) No candidate musical pieces capable of satisfying the music splicing condition are detected.
In the case of the execution result (2), one candidate musical piece satisfying the music splicing condition may be selected as the second musical piece by means of random selection or the like.
In the case of execution result (3), the process goes to step S505, where one candidate musical piece is selected as the second musical piece by means of random selection or the like.
By executing steps S501 to S505, the second music piece can be determined. Because the second music piece is searched according to the second emotion information, the second music piece can be matched with the second emotion information, and on the basis, the second music piece and the first music piece can also meet the music splicing condition.
In this embodiment, when step S6 is performed, that is, the step of splicing the first music piece and the second music piece to obtain spliced music, the following steps may be specifically performed:
s601, when the second music piece meets the music splicing condition, splicing the ending part of the first music piece with the beginning part of the second music piece to obtain spliced music;
s602, when the second music piece does not meet the music splicing condition, generating a transition music piece;
s603, splicing the tail part of the first music piece with the head part of the transition music piece, and splicing the tail part of the transition music piece with the head part of the second music piece to obtain spliced music.
If the second piece of music is obtained by performing step S504, referring to fig. 4, step S601 is performed to stitch the ending part of the first piece of music with the beginning part of the second piece of music to obtain stitched music. Under the condition that the second music piece and the first music piece meet the music splicing condition, the first music piece and the second music piece can be directly spliced together, and the splicing music has the natural transition effect of 'music string burning' when played.
If the second music piece is obtained by executing step S505, referring to fig. 5, steps S602-S603 are executed to stitch the first music piece, the transition music piece, and the second music piece together end to end in order, thereby obtaining stitched music. Under the condition that the second music piece and the first music piece do not meet the music splicing condition, the transition music piece which meets the music splicing condition respectively between the second music piece and the first music piece and between the second music piece and the first music piece is obtained, and the transition music piece is inserted between the first music piece and the second music piece, so that the influence of the condition that the second music piece and the first music piece do not meet the music splicing condition is relieved, and the natural transition effect of 'music string burning' is achieved when the spliced music is played.
In this embodiment, when step S602, that is, the step of generating the transition piece of music is performed, the following steps may be specifically performed:
s60201, acquiring first audio information from a first music piece;
s60202, acquiring second audio information from a second music piece;
s60203, acquiring information of the current vehicle exterior environment to obtain third audio information;
s60204, inputting the first audio information, the second audio information and the third audio information into an artificial intelligent model for processing; the artificial intelligent model has automatic composing performance;
s60205, obtaining an output result of the artificial intelligence model as a transition music piece.
The control module may run the artificial intelligence model locally or request the cloud-run artificial intelligence model to provide services through the communication module while performing steps S60201-S60205. The artificial intelligent model is trained and can automatically make a music according to the audio information. For example, using an artificial intelligence model based on time series processing, the artificial intelligence model may process the input audio information into a time series, the artificial intelligence model performs a time series prediction algorithm, predicts new audio information based on the existing time series, and the predicted new audio information together with the original audio information may be outputted as a new music piece obtained by automatic composition of the artificial intelligence model.
In step S60201, the control module performs time domain analysis, frequency domain analysis, and other processes on the first music piece, and obtains first audio information such as waveforms or frequency spectrums. Based on the same principle, in step S60202, the control module performs time domain analysis, frequency domain analysis, and other processes on the second music piece, to obtain second audio information such as waveforms or frequency spectrums.
In step S60203, information is collected from the current vehicle exterior environment to obtain third audio information. Specifically, the control module may invoke a sound sensor installed on the automobile to collect a tire noise, a wind noise, a side vehicle or a sound emitted by a pedestrian in an environment outside the automobile, so as to obtain third audio information. Or the control module can call an image sensor installed on the automobile, shoot the outside environment of the automobile, obtain a two-dimensional image, then perform dimension reduction processing on the two-dimensional image, and the obtained one-dimensional information can be expressed as third audio information.
In step S60204, under the condition that the artificial intelligent model is operated by the cloud, the control module uploads the first audio information, the second audio information and the third audio information to the server through the communication module, and the server inputs the first audio information, the second audio information and the third audio information to the artificial intelligent model for processing. The first audio information, the second audio information, and the third audio information may form a time series, and the artificial intelligence model predicts the time series to populate the predicted audio information between the first audio information and the second audio information, and between the second audio information and the third audio information.
In step S60205, the first audio information, the second audio information, the third audio information, and the padded predicted audio information constitute a transition piece of music.
In this embodiment, the principle of performing steps S60201-S60205 is that: the first audio information, the second audio information and the third audio information respectively determine key information of the beginning, the middle and the end of the last obtained transition music piece, and the complete transition music piece is obtained through the automatic composing function of the artificial intelligent model; the beginning of the transition music piece is determined by the first audio information, so that the natural transition effect of 'music string burning' is obtained after the transition music piece is spliced with the first music piece; the end of the transition music piece is determined by the second audio information, so that the natural transition effect of 'music string burning' is obtained after the transition music piece is spliced with the second music piece; the middle part of the transition music piece is determined by the third audio information, so that the artificial intelligent model is favorable for 'creating' according to the vehicle exterior environment, and the transition music piece content with the style matched with the current driving environment is obtained, thereby being favorable for the sound effect played by the transition music piece, having the characteristics matched with the current driving environment, and enhancing the driving pleasure.
In this embodiment, when step S7 is performed, that is, the step of synchronously switching the playing of the first music piece to the playing of the spliced music, the following steps may be specifically performed:
s701, acquiring a current playing position of a first music piece;
s702, determining an initial playing position in spliced music according to the current playing position;
s703, stopping playing the first music piece;
s704, starting from the initial playing position, playing spliced music.
The principle of steps S701-S704 is shown in fig. 6.
When steps S701-S702 are performed, the spliced music may be aligned with the beginning of the first music piece, and then the absolute position of the start play position in the time axis of the spliced music is the same as the absolute position of the current play position in the time axis of the first music piece.
When executing steps S703-S704, immediately starting from the start playing position after stopping playing the first music piece, playing the spliced music, so that the on-board personnel cannot perceive that the switching has been completed, thereby realizing a smooth playing effect.
In this embodiment, when step S7 is performed, that is, the step of synchronously switching the playing of the first music piece to the playing of the spliced music, the following steps may be further performed:
s705, detecting driving parameters of the automobile;
s706, determining an acceleration multiplying power according to driving parameters;
s707, determining a target splicing position;
s708, when the spliced music is played, the part from the initial playing position to the target spliced position in the spliced music is accelerated to play according to the acceleration multiplying power, and other parts in the spliced music are played at the original speed.
The principle of steps S705-S708 is shown in fig. 7.
When executing step S705, the control module may invoke the sensing module to detect and obtain driving parameters such as the engine speed, the steering amplitude of the steering wheel, the current vehicle speed, the current acceleration, and the like. The control module may select one of the driving parameters, or may select a vector composed of a plurality of driving parameters, and execute S706.
In step S706, taking the control module selecting the driving parameter "current vehicle speed" as an example, the control module may set an acceleration rate, and set the acceleration rate to be positively correlated with the driving parameter, that is, the larger the current vehicle speed is, the larger the acceleration rate is (the acceleration rate is constantly greater than 1).
In step S707, as shown in fig. 7, in the case where the spliced music is formed by splicing the first music piece, the second music piece, and the transition music piece, the splice position of the portion corresponding to the transition music piece and the portion corresponding to the second music piece is the target splice position. In the case where the piece of music is formed by stitching a first piece of music with a second piece of music, the stitching position of the portion corresponding to the first piece of music and the portion corresponding to the second piece of music is the target stitching position.
When step S708 is executed, referring to fig. 7, the portion of the spliced music from the start playing position to the target splicing position is accelerated to play according to the acceleration rate; specifically, the control module may obtain a preset playing rate of the portion, take a product of the preset playing rate and the acceleration rate as an actual playing rate, and play the portion according to the actual playing rate; and playing other parts in the spliced music, namely the parts from the target splicing position to the end, according to the preset playing rate of the parts.
In this embodiment, the principle of performing steps S705 to S708 is that: by accelerating the playing of the part from the initial playing position to the target splicing position in the spliced music, the corresponding part of the second music piece in the spliced music can be played in advance on the basis of realizing the 'serial burning' effect of natural transition, so that the new emotion requirement of the personnel on the vehicle can be met as soon as possible; in addition, the acceleration degree of the accelerated playing is related to the driving parameters of the automobile, and since the driving parameters of the automobile are related to the driving behaviors of the driver, and the driving behaviors of the driver are affected by the emotion of the driver, the latest emotion information of the driver, which is included in the driving parameters of the automobile, can be used as a control variable, for example, in the case that the emotion of the driver is more impatient, a larger speed or acceleration is often generated, and the steps S705-S708 are executed to play the second music piece as soon as possible through accelerating the part before the second music piece, so that the emotion relieving effect of the second music piece is facilitated to arrive as soon as possible, and the emotion relieving effect of the music is improved.
