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, an environmental information detection 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 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 fig. 1, the environmental information detection module may collect information about an automobile surrounding environment through the environmental information detection module, for example, the environmental information detection module may include a camera, a sound sensor, a wind speed sensor, a temperature sensor, a humidity sensor, and other sensors, and a satellite navigation module, and through these sensors and modules, the environmental information detection module collects environment information outside the automobile such as a live image, environmental noise, wind speed, air temperature, air humidity, and a real-time position of the automobile surrounding environment, where the environmental information detection module or the control module performs image analysis on the live image, and can identify information about an environment type (for example, urban area, suburban area, and mountain area), a road type (for example, expressway, national road, provincial road, county road), a number of surrounding pedestrians, or vehicles, and further identify information about an external environment such as a congestion degree (for example, smooth, moderate congestion, and serious congestion) of the automobile at the location.
In fig. 1, the environmental information detection module may also download the in-vehicle environmental information from the server by connecting to the server. The server may acquire the latest in-vehicle environment information from the data detection stations provided at the respective locations, or accept vehicles at the respective locations to upload in-vehicle environment information of the respective locations they detected. In this case, the environmental information detection module itself may not have a detection function, but may have a data reception function, and the environmental information detection module may receive the outside environment information of other locations than the current location of the automobile, such as the destination of the automobile, or the outside environment information at a plurality of locations on the route from the current location of the automobile to the destination.
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 target music according to the first emotion information;
s3, playing target music;
s4, detecting the information of the outside environment of the vehicle;
s5, according to the information of the outside environment of the automobile, adjusting the playing content of the target 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 matched with the first emotion information from the local song library or cloud, the music information is read or downloaded to the control module, and the target music is obtained. In this embodiment, the target music may be a complete song, such as a popular song with a definite song name and singer, including a pre-song, a main song, a sub-song, a transitional sentence, a popular sentence, and a bridge segment.
In step S3, the control module decodes the target music, 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 playing of target music is realized.
In step S4, the control module triggers the environmental information detection module to detect the surrounding environment of the current position of the automobile by itself, or downloads the surrounding environment detection data of the current position or other positions of the automobile from the server, thereby obtaining the vehicle external environment information. The environment information detection module sends the detected environment information outside the vehicle to the control module.
In step S5, the control module adjusts the playing content of the target music played in step S3 according to the in-car environment information sent by the environment information detection module. The adjusted target music is played, and after the adjusted target music is heard by the vehicle occupant, the generated hearing effect is different from the hearing effect which is generated by the vehicle occupant assuming that the unadjusted target music is played.
The principle of performing steps S1-S5 is that: the target music played in the steps S1-S3 is matched with the identified first emotion information, so that the emotion represented by the first emotion information of the personnel on the vehicle can be enhanced (positive emotion) or relieved (negative emotion); the executing of the step S4 also affects the emotion of the person in the vehicle (for example, the air temperature and the humidity represented by the in-vehicle environment information can affect the body feeling of the person in the vehicle, the environment type, the road type, the congestion degree and the like represented by the in-vehicle environment information can affect the driving experience of the person in the vehicle), so that the emotion of the person in the vehicle deviates from the emotion type represented by the first emotion information, and therefore, by executing the step S5, the played content of the target music is adjusted according to the in-vehicle environment information, the played hearing effect can be generated based on the target music, and the macroscopic requirement caused by the emotion represented by the first emotion information of the person in the vehicle can be met, and the microscopic requirement caused by the emotion fluctuation generated by the in-vehicle environment information can be met, so that the vehicle-mounted music is more flexible and fine to the emotion of the person in the vehicle, and the situation that the emotion of the person in the vehicle is difficult to match the situation after the change of the person in the vehicle is caused by the music song determined by the first emotion information can be avoided.
In this embodiment, when the control module performs step S4, that is, the step of detecting the vehicle exterior environment information, the following steps may be specifically performed:
S401A, detecting the environment outside the vehicle in real time to obtain the information of the environment outside the vehicle.
Step S401A is a first implementation of step S4.
When the step S401A is executed, the environment information detection module detects the surrounding environment of the automobile in real time to obtain the information of the outside environment of the automobile; under the condition that the environment information detection module downloads data from the server, the environment information detection module can only download the vehicle exterior environment information of the surrounding environment where the vehicle is currently located.
In this embodiment, on the basis of executing step S401A, the control module may specifically execute the following steps when executing step S5, that is, the step of adjusting the playing content of the target music according to the in-vehicle environment information:
S501A, determining second emotion information according to the vehicle exterior environment information and the first emotion information;
S502A, acquiring a part to be played of target music;
S503A, decoding the part to be played to obtain waveform information;
S504A, adjusting the waveform information according to the second emotion information.
Steps S501A-S504A are the first implementation of step S5.
The principle of steps S501A-S504A is shown in fig. 3.
Referring to fig. 3, in step S501A, the control module determines second emotion information according to the vehicle exterior environment information and the first emotion information. Specifically, the control module may locally pre-store a data table, where the form of the data table is shown in table 1. Table 1 can represent that when a person on the vehicle is affected by the outside environment represented by the in-vehicle environment information with the emotion represented by the first emotion information, the emotion of the person on the vehicle fluctuates and becomes the emotion represented by the second emotion information. By querying the data table, the second mood information can be determined given the in-vehicle environment information and the first mood information.
TABLE 1
| Vehicle external environment information (Congestion degree) | First emotion information | Second emotion information |
| Smooth and smooth | Tension is intense | Shu Chang |
| Moderate congestion | Tension is intense | Tension is intense |
| Severe congestion | Tension is intense | Anger |
| …… | …… | …… |
Referring to fig. 3, in step S502A, first, from the playback time axis of the target music, the position to which playback is performed at the time of step S5, that is, the current playback position is determined. The portion of the target music before the current play position is a played portion, and the portion after the current play position is an unreplayed portion. And (3) starting from the current playing position, cutting out a part from the target music along the time axis for a certain period of time, and obtaining the part to be played.
Referring to fig. 3, in step S503A, the control module decodes the portion to be played using a music decoding algorithm to obtain waveform information before adjustment.
Referring to fig. 3, in step S504A, the control module adjusts the waveform information according to the second emotion information, and generates a control signal according to the adjusted waveform information, so as to control the music playing module to play the adjusted waveform information.
In step S504A, the control module may perform adjustment processing such as variation, pitch, and speed change on the waveform information according to the second emotion information, so as to adjust the hearing effect of the portion to be played, so that the hearing effect generated when the adjusted waveform information is played can satisfy the emotion requirement represented by the second emotion information of the person on the vehicle.
For example, when the second emotion information indicates tension, in step S504A, the control module accelerates the waveform information, and weakens the low frequency component in the waveform information while maintaining the high frequency component in the waveform information unchanged, so that the adjusted waveform information is played to generate an auditory effect, which has a light feeling, is beneficial to relieving tension emotion of the personnel on the vehicle, and meets emotion requirements of the second emotion information representation of the personnel on the vehicle.
By executing steps S501A-S504A, the auditory effect of the target music played can be adjusted in real time according to the latest detected vehicle exterior environment information, so that the vehicle-mounted music is more sensitive to the adjustment of the emotion of the person on the vehicle.
In this embodiment, referring to fig. 3, when step S502A is executed, the duration of the upcoming playing portion that is intercepted by the control module from the target music is T coming . The control module may perform the following steps to intercept the upcoming play section:
s50201, determining similarity between the first emotion information and the second emotion information;
s50202 determining the intercepting time length T according to the similarity coming ；
S50203, starting from the current playing position in the target music, cutting out a part which is equivalent to the cutting-out duration and is used as a part to be played.
In step S50201, the control module may set a certain score for each type of emotion such as happiness, tension, low level, sadness, etc., for example, a score of positive value indicates that the emotion type is positive, a score of negative value indicates that the emotion type is negative, so that the first emotion information and the second emotion information will have respective scores. And then the control module calculates the absolute value of the difference between the corresponding scores of the first emotion information and the second emotion information, and determines the similarity between the first emotion information and the second emotion information according to the absolute value, wherein the smaller the absolute value is, the larger the similarity is.
In step S50202, the time length T is intercepted coming Is inversely related to the similarity, i.e. the greater the similarity is, the longer the time length T is intercepted coming Smaller, smaller reverse similarity is the intercepting duration T coming The larger.
In this embodiment, the principle of performing steps S50201-S50203 is that: the second emotion information is the emotion type of the personnel on the vehicle under the condition of considering the environment outside the vehicle, so that the similarity between the first emotion information and the second emotion information can represent the emotion variation degree of the personnel on the vehicle under the condition of being influenced by the environment outside the vehicle, and the larger the similarity is, the smaller the emotion variation degree is; when the similarity is smaller, namely the emotion variation degree is larger, the time length T is intercepted coming The bigger, namely intercepting the longer part to be played is adjusted, so that the requirement of the greater emotion variation degree on adjusting emotion of music is easily met.
In this embodiment, when the control module performs step S4, that is, the step of detecting the vehicle exterior environment information, the following steps may be specifically performed:
S401B, acquiring the playing time length of an unreleased part of target music;
S402B, acquiring a navigation task of the automobile;
S403B, determining a future driving road section matched with the playing time length according to the navigation task;
S404B, detecting by taking a future driving road section as a detection target, and obtaining the vehicle exterior environment information.
Steps S401B-S404B are the second implementation of step S4.
The principle of steps S401B-S404B is shown in fig. 4 and 5.
In step S401B, the control module determines the duration from the current playing position to the end by searching the playing time axis of the target music, and obtains the playing duration T of the unreported part not_played 。
In step S402B, the control module invokes the satellite navigation module in the environmental information detection module to obtain a navigation task of the automobile.
In step S403B, the control module determines a route of the automobile from the current location to the destination according to the navigation task. Starting from the current position in the route, calculating and obtaining the running time length of the automobile and the playing time length T of the unreleased part according to the current running state of the automobile, road conditions and other information not_played In the same caseThe automobile can reach the position along the route represented by the navigation task. The part from the current position to the reachable position in the route represented by the navigation task is the playing time length T not_played Matched future travel sections.
Upon execution of step S404B, the environmental information detection module may download the in-vehicle environmental information from the server. Referring to fig. 4 or 5, the server collects the vehicle exterior environment information detected by the detection points 1 and 2, the vehicle exterior environment information detected by the detection points 2 and … …, the vehicle exterior environment information detected by the detection points 1 and 2, the vehicle exterior environment information 1 and 2 and … …, the vehicle exterior environment information n are formed by the time sequence from the detection points 1 and 2, … … (the detection points may be fixed detection stations or other vehicles running to the positions).
In this embodiment, on the basis of executing steps S401B-S404B, the control module may specifically execute the following steps when executing step S5, that is, the step of adjusting the playing content of the target music according to the in-vehicle environment information:
S501B, obtaining an unreleased part of target music;
S502B, dividing the unplayed part into a plurality of first music pieces;
S503B, establishing a corresponding relation between each first music piece and each detection point;
S504B, for any first music piece, acquiring the in-car environment information of a detection point corresponding to the first music piece, determining second emotion information according to the in-car environment information and the first emotion information, and adjusting the first music piece according to the second emotion information; the adjusted acoustic parameters of the first musical piece are matched with the second emotion information.
Steps S501B-S504B are the second implementation of step S5.
The principle of steps S501B-S504B is shown in fig. 4.
In step S502B, the control module divides the unplayed portion into a plurality of first music pieces. Specifically, the number of the first music pieces may be the same as the number of the detection points, and the play duration of each first music piece may be the same as the piece estimated travel duration of the future travel section corresponding to the corresponding detection point. For example, referring to fig. 4, n detection points are set in total, and n pieces of in-vehicle environment information such as in-vehicle environment information 1, in-vehicle environment information 2 … …, and the like are detected respectively, and then the unplayed portion is divided into n pieces of first music such as first music piece 1, first music piece 2 … …, first music piece n, and the like. The playing duration of the first music piece 1 is the same as the estimated running duration of the automobile from the starting point of the future running road section to the position of the detection point 1 under the road condition of the future running road section and the current running condition of the automobile in fig. 4; the playing duration of the first music piece 2 is the same … … as the expected running duration of the automobile from the position of the detection point 1 to the position of the detection point 2, and the playing duration of the first music piece n is the same as the expected running duration of the automobile from the position of the detection point n to the end point of the future running road section.
In step S504B, referring to fig. 4, taking the first music piece 3 as an example, the in-car environment information 3 detected by the detection point 3 corresponding to the first music piece 3 is acquired, the second emotion information 3 is determined according to the in-car environment information 3 and the first emotion information (the principle is the same as that in step S501A), and the first music piece 3 is adjusted according to the second emotion information 3 so that the acoustic parameters of the adjusted first music piece are matched with the second emotion information (the principle is the same as that in step S504A). The same operation is also performed for any other first music piece.
In this embodiment, the principle of performing steps S501B-S504B is that: by taking the future driving road section as a target, the information of the outside environment of the vehicle at the position where the vehicle does not drive can be detected, and the unplayed part of the target music can be adjusted in advance, so that when the vehicle drives to a specific position of the future driving road section, the unplayed part of the target music is played to the corresponding position, and the hearing effect of the unplayed part of the target music is matched with the emotion of the personnel on the vehicle after the influence of the outside environment of the vehicle; in addition, in the steps S501B-S504B, the adjustment processing such as variation, tone change, speed change is performed on part or all of the segments in the unplayed part, so that the music playing module can always keep playing the target music, and operations such as "cutting song" are not required, and phenomena such as music pause and the like in the process of "cutting song" are avoided, so that a more natural playing effect is achieved, the effect change of music enhancement or emotion relief is achieved, the emotion change of the personnel on the vehicle can be approached, and a good emotion improvement effect is facilitated.
In this embodiment, on the basis of executing steps S401B-S404B, the control module may specifically execute the following steps when executing step S5, that is, the step of adjusting the playing content of the target music according to the in-vehicle environment information:
S501C, dividing the unplayed part into a plurality of first music pieces;
S502C, establishing a corresponding relation between each first music piece and each detection point;
S503C, for any first music piece, acquiring in-car environment information of a detection point corresponding to the first music piece, determining second emotion information according to in-car environment information and the first emotion information, acquiring a second music piece according to the second emotion information, matching the second music piece with the second emotion information, and replacing the first music piece with the second music piece.
Steps S501C-S503C are a third implementation of step S5.
The principle of steps S501C-S503C is shown in fig. 5.
Steps S501C-S502C are identical to steps S501B-S502B.
In step S503C, referring to fig. 5, taking the first music piece 3 as an example, the in-car environment information 3 detected by the detection point 3 corresponding to the first music piece 3 is obtained, the second emotion information 3 is determined according to the in-car environment information 3 and the first emotion information (the principle is the same as that of step S501A), and the second music piece 3 is obtained according to the second emotion information 3; specifically, if the control module finds a plurality of second music pieces matched with the second emotion information 3 from the local or cloud song library, the control module may set a music stitching condition according to a rule of "music string burn", for example, the music stitching condition may specifically include: of the two pieces of music spliced, the last part of the preceding piece of music is similar in tune, song style is similar, or lyrics is rhythmed, etc., to the beginning part of the following piece of music, then a second piece of music satisfying the music splicing condition (for example, a second piece of music selected, the beginning part of which is similar in tune, song style is similar, or lyrics is rhythmed to the beginning part of the first piece of music 2 or the end part of the second piece of music 2, the ending part of which is similar in tune, song style is similar, or lyrics is rhythmed to the beginning part of the first piece of music 4 or the second piece of music 4) is selected as the second piece of music 3 (in the case of selecting a plurality of second pieces of music, one second piece of music may be randomly selected).
In step S503C, taking the first music piece 3 therein as an example, when the first music piece 3 is replaced with the second music piece 3, the second music piece 3 may be spliced together with the first music piece 2 (if the first music piece 2 is not replaced) or the second music piece 2 (if the first music piece 2 is replaced) and the second music piece 3 may be spliced together with the first music piece 4 (if the first music piece 4 is not replaced) or the second music piece 4 (if the first music piece 4 is replaced) by a music splicing (where "splicing" is also sometimes referred to as "mix-splice", "merge", "composite", or the like) technique, thereby forming spliced music, colloquially referred to as "music burn.
In this embodiment, the principle of performing steps S501C-S503C is that: by taking the future driving road section as a target, the information of the outside environment of the vehicle at the position where the vehicle does not drive can be detected, and the unplayed part of the target music can be adjusted in advance, so that when the vehicle drives to a specific position of the future driving road section, the unplayed part of the target music is played to the corresponding position, and the hearing effect of the unplayed part of the target music is matched with the emotion of the personnel on the vehicle after the influence of the outside environment of the vehicle; in addition, in the steps S501C-S503C, part or all of the segments in the unplayed portion are replaced by new music segments (i.e., the second music segments), so that a "music serial burn" is formed, the music playing module can always keep playing the target music without performing operations such as "cutting song", and the like, and the phenomenon of music pause and the like existing in the process of "cutting song" is avoided, so that the music playing device has a more natural playing effect, the effect change of enhancing or soothing emotion of the music can approach to the emotion change of the personnel on the vehicle, and a good emotion improvement effect is facilitated.
The same technical effects as those of the vehicle-mounted music playing method in the embodiment can be achieved by writing a computer program for executing the vehicle-mounted music playing method in the embodiment into a computer device or a storage medium, and executing the vehicle-mounted music playing method in the embodiment when the computer program is read out to run.
