[0002] With the rapid development of the economy and society, the travel mode is constantly enriched, and various vehicle types emerge as the times require. The increase of different vehicle types and the number of vehicles brings more and more pressure to the road traffic, so at the position of the traffic light, the vehicle queue is often long and slow. In this case, many drivers will honk because of impatience or because the front vehicle does not proceed in time. Such honking will bring great sound pollution to people around work and life.

[0003] For the above situation, the government has introduced some regulations to control the honking noise, such as imposing punishment measures on honking vehicles in the range where honking is prohibited. However, due to the inaccuracy of honking sound positioning, especially in the area where vehicles are concentrated, it is difficult to accurately position. Therefore, even if it is detected that a vehicle is honking, it is difficult to implement the punishment measures due to the inability to accurately position.

[0054] The present application will be further described below in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application. In addition, it should be noted that, for the convenience of description, only the parts related to the present application are shown in the drawings, but not all the structures.

[0055] Before the example embodiments are discussed in more detail, it should be mentioned that some example embodiments are described as processes or methods depicted as flow charts. Although the flow charts depict the steps in a sequential order, many of the steps can be performed in parallel, concurrently or at the same time. In addition, the order of the steps can be rearranged. The processes can be terminated when their operations are completed, but can also have additional steps not included in the figures. The processes can correspond to methods, functions, routines, subroutines, subprograms, etc.

[0056] Figure 1 is a flow chart of a positioning method for vehicle horn provided by an embodiment of the present application. The embodiment can be applicable to the positioning of vehicle horn. The method can be performed by a positioning device for vehicle horn provided by an embodiment of the present application. The device can be realized by software and / or hardware, and can be integrated in an electronic device.

[0057] As shown in Figure 1 , the positioning method for vehicle horn comprises:

[0058] S110, obtaining sound information of a target section by a pickup array; wherein the target section is paved with the pickup array, and the pickup array comprises at least two pickups.

[0059] The pickup array can be composed of multiple pickups. For example, the pickups can be arranged in a row-column manner to form a pickup array. The target section can be a region where the vehicle is prone to honk, such as an intersection position. The target section can also be a part of the region where the honking is limited, such as a region with a school, a kindergarten, etc. In this case, one or more target regions on the road around the school and the kindergarten can be selected for vehicle honking monitoring, so as to better avoid the influence of vehicle honking on students and children.

[0060] Figure 2 is a schematic diagram of pickup arrangement positions provided by an embodiment of the present application. As Figure 2As shown, the dots indicate the placement of the microphones. It can be understood that the microphone array can be laid on the ground of the target road section. Specifically, it can be laid at equal intervals; for example, the array arrangement can be based on the size of the no-honking zone intersection, with microphones evenly placed. The distance between array units, i.e., each microphone, can be deployed according to the actual area, preferably at a distance greater than 0.5m, such as one microphone every 0.6m or 0.8m.

[0061] Figure 3 This is a schematic diagram of the connection relationship of the microphone provided in an embodiment of this application. For example... Figure 3 As shown, this solution can be executed by a processing unit connected to each microphone. Alternatively, each microphone can be equipped with a processor, and the operation can be performed by that processor. In cases involving multiple microphones working together, a network can be formed based on the ID of each microphone, and the operation can ultimately be executed by the processor of one of the microphones in the network.

[0062] In this solution, the sound information can include vehicle horn sounds, as well as sounds produced by the vehicle engine and tires. Since vehicle horn sounds are relatively loud and sharp, specific sampling can be performed targeting the frequency of the horn sound.

[0063] S120. If a vehicle horn event is detected based on the sound information, the volume value of the pickup in the pickup array is determined.

[0064] In this solution, for example, detecting a vehicle horn event based on the sound information includes:

[0065] The sound information is divided into frequency bands, and the monitoring frequency band for horn-honking events is determined;

[0066] If the volume of at least one horn event monitoring frequency band exceeds the first preset volume, it is determined that a vehicle horn event has been detected.

[0067] or,

[0068] If the volume of the detected sound information exceeds the second preset volume, it is determined that a vehicle horn event has been detected, and the sound information is analyzed to obtain the frequency band corresponding to the vehicle horn event.

[0069] By using such data collection or analysis methods, it is possible to more accurately determine whether a vehicle horn honking incident has occurred.

[0070] Determining the volume value of the microphones in the microphone array can be done by determining the volume value of each individual microphone, or by determining the volume value of the microphone that detected a vehicle horn honking event.

[0071] S130. Determine the target pickup position based on the volume value to obtain the vehicle horn location.

[0072] In the scheme, the position of the vehicle horn can be determined according to the size relationship between the volume values of the pickups, for example, the position of the vehicle horn is the position with the maximum volume value.

[0073] In an embodiment, the position of the target pickup corresponding to the position of the vehicle horn is determined according to the volume values, comprising:

[0074] The position of the target pickup corresponding to the position of the vehicle horn is determined by using a pickup and neighborhood pickup election recursion method according to the volume values of the pickups and the positions of the pickups in the pickup array, wherein the election condition of the election recursion method is that the pickup with the maximum volume value is the election winner.

[0075] Since the positions of the pickups are different, for example, the positions can be associated with the layout positions and the pickup IDs, so that after obtaining the ID of a pickup, the position of the pickup can be determined.

[0076] After obtaining the volume values of the pickups and the positions of the pickups, the position of a pickup is determined, and the positions of the neighborhood pickups are determined according to the position, wherein the neighborhood pickups can be the pickups in the eight neighborhoods of up, down, left, right, upper left, upper right, lower left, and lower right (the directions are the directions in the top view). The neighborhood pickups can be the pickups around the current pickup, for example, if the current pickup is in the third row and the third column, the second column to the fourth column in the second row, the second column and the fourth column in the third row, and the second column to the fourth column in the fourth row can be the neighborhood pickups. In addition, the range of the neighborhood can be expanded, which will cause a larger calculation amount, but the calculation result will be more accurate.

[0077] The election recursion method can be to perform election again with the pickup with the maximum volume value obtained after the election of the current nine pickups as the center. The advantage of this setting is to complete the accurate positioning of the position of the vehicle horn in a constant calculation amount.

[0078] In an embodiment, the pickup and neighborhood pickup election recursion method comprises:

[0079] A to-be-identified pickup and neighborhood pickups adjacent to the to-be-identified pickup are determined.

[0080] The volume value of the to-be-identified pickup and the volume values of the neighborhood pickups are determined.

[0081] The pickup with the maximum volume value is elected as the election winner.

[0082] If the election winner is one of the neighborhood microphones, then the election winner is taken as a new microphone to be identified, and a new neighborhood microphone adjacent to the new microphone to be identified;

[0083] The election is performed again until the election winner is the new microphone to be identified itself, and then the final election winner is determined as the target microphone.

[0084] The position with the maximum volume value is taken as the election winner, and then the election is performed again with the position as the center until the position with the maximum volume value is just at the center position, which indicates that the volume values obtained by other microphones around the microphone are all smaller than the volume value of the microphone, and the position of the microphone is closest to the position of the vehicle honking.

[0085] The technical scheme provided in the embodiments of the present application acquires sound information of a target road section through a microphone array; the target road section is paved with the microphone array, and the microphone array includes at least two microphones; if a vehicle honking event is detected according to the sound information, volume values of the microphones in the microphone array are determined; and a target microphone position is determined according to the volume values to obtain a vehicle honking position. The technical scheme provided in the present application can achieve the purpose of accurately positioning the vehicle honking position through the microphone array by paving the microphone array on the ground.

[0086] On the basis of the above technical schemes, after the target microphone position is determined according to the volume values to obtain the vehicle honking position, the method further includes:

[0087] The target microphone position is sent to an evidence collection system, so that the evidence collection system records vehicle honking evidence according to the target microphone position.

[0088] The evidence collection system can include a fisheye camera arranged at an intersection or a violation recording camera arranged above a road. The present scheme can connect the two systems, and after the vehicle honking position is obtained, the vehicle honking position can be provided to the camera. After the camera takes a picture, the position of the vehicle in the image can be determined to determine which vehicle is honking, and license plate information of the vehicle is obtained as vehicle honking evidence for recording. The advantage of this arrangement is that the vehicle honking position can be accurately positioned after the vehicle honks, and the evidence of the vehicle passing through the intersection can be recorded, so that the vehicle honking evidence record is more accurate and reliable.

[0089] Figure 4is a flowchart of a positioning method of a vehicle horn provided by an embodiment of the present application. The technical solution is further optimized on the basis of the above technical solution, and the specific optimization is that the target road section is also paved with a loudspeaker array.

[0090] Correspondingly, after determining the target microphone position corresponding to the vehicle horn position according to the volume value, the method further includes:

[0091] acquiring audio information of the vehicle horn through the target microphone, and determining a target loudspeaker in the loudspeaker array based on the target microphone position.

[0092] determining noise cancellation sound information according to the audio information, and emitting the noise cancellation sound information through the target loudspeaker to perform noise cancellation processing.

[0093] As shown in Figure 4 the method includes:

[0094] S410, acquiring sound information of a target road section through a microphone array; wherein the target road section is paved with a microphone array, and the microphone array includes at least two microphones.

[0095] S420, if a vehicle horn event is detected according to the sound information, determining a volume value of a microphone in the microphone array.

[0096] S430, determining a target microphone position according to the volume value to obtain a vehicle horn position.

[0097] S440, acquiring audio information of the vehicle horn through the target microphone, and determining a target loudspeaker in the loudspeaker array based on the target microphone position.

[0098] After determining the target microphone position, the sound characteristics of the vehicle horn, such as frequency, amplitude, and phase, can be determined according to the audio information collected by the target microphone.

[0099] Since there are multiple loudspeakers in the loudspeaker array, the loudspeaker closest to the vehicle horn position can be determined as the target loudspeaker. Specifically, after determining the target microphone position, the loudspeaker ID closest to the position can be determined according to the correspondence between the position and the loudspeaker ID in the loudspeaker queue, and the loudspeaker with the loudspeaker ID is taken as the target loudspeaker.

[0100] Here, the loudspeakers and microphones can be arranged at the same point, such as each microphone position being provided with a loudspeaker. Then, the loudspeaker ID corresponding to the microphone ID can be determined according to the microphone ID, so that after determining the target microphone position, the target loudspeaker can be determined.

[0101] In the scheme, the deployment positions of the loudspeakers and the microphones are paired with each other. Figure 5 is a schematic diagram of microphone and loudspeaker deployment positions provided by an embodiment of the present application. As shown in Figure 5 , the positions of four microphones and one loudspeaker can be associatedly set, and based on this, the loudspeakers and the microphones are paired according to the deployment positions, as shown in the following table.

[0102] Pairing number Speaker Microphone 1 Speaker 1-1 Microphone 1-1, microphone 2-1, microphone 1-2, microphone 2-2 2 Speaker 2-1 Microphone 2-1, microphone 3-1, microphone 2-2, microphone 3-2 3 …… ……

[0103] Figure 6 is a schematic diagram of the connection relationship of loudspeakers provided by an embodiment of the present application. As shown in Figure 6 , it can be understood that one audio processing unit can be configured for each loudspeaker in the loudspeaker array, or all the loudspeakers can be connected to the same audio processing unit, and the audio processing unit can control the loudspeakers according to the loudspeaker ID.

[0104] Figure 7 is a schematic diagram of vehicle horn effect provided by an embodiment of the present application. As shown in Figure 7 , when the vehicle honks on the microphone ground array, the sound wave takes the horn position of the honking vehicle as the center point and propagates to the surrounding along the ground.

[0105] Further, the position can be located according to the above-mentioned election recursion method, and the algorithm flow is as follows:

[0106] 1. The sensor S with ID number S_i_j determines the ID numbers of the surrounding eight sensors as:

[0107] S_i-1_j-1, S_i_j-1, S_i+1_j-1,

[0108] S_i-1_j, S_i_j, S_i+1_j,

[0109] S_i-1_j+1, S_i_j+1, S_i+1_j+1,

[0110] 2. The audio intensity is calculated according to the audio spectrum segmentation.

[0111] 3. The audio intensity values divided according to the spectrum are sent to the surrounding eight sensors.

[0112] 4. The independent intensity values divided according to the frequency band are compared, and the one with high intensity wins.

[0113] 5. The winning sensor continues to send the audio intensity information to the unselected sensors until the surrounding eight sensors of the sensor are all selected.

[0114] 6. The position of the sensor is the horn position of the honking vehicle.

[0115] Figure 8 is a schematic diagram of a vehicle horn position election recursion process provided by an embodiment of the present application. As shown, an election winner is obtained by election in turn, and recursion is performed in the order of the arrows in the figure, and finally the vehicle horn position is obtained. Figure 8

[0116] S450, determine the noise cancellation sound information according to the audio information, and emit the noise cancellation sound information through the target speaker to perform noise cancellation processing.

[0117] In the present scheme, the noise cancellation sound information can be determined according to the audio information, and the frequency, amplitude and phase of the audio information are determined by using active noise reduction, and the noise cancellation sound information with the same frequency, amplitude and opposite phase is used for noise cancellation processing, so as to achieve the purpose of noise reduction.

[0118] The technical scheme provides a noise cancellation scheme after positioning the vehicle horn position. Through such a setting, noise can be effectively eliminated, and the experience of surrounding residents or pedestrians can be improved.

[0119] On the basis of the above technical schemes, optionally, the target road section is also paved with a noise cancellation effect evaluation microphone;

[0120] Correspondingly, after emitting the noise cancellation sound information through the target speaker to perform noise cancellation processing, the method further comprises:

[0121] Determine whether the noise cancellation effect meets the preset standard through the sound information obtained by the noise cancellation effect evaluation microphone;

[0122] If not, adjust the noise cancellation sound information.

[0123] The noise cancellation effect evaluation microphone can be one or more of ordinary microphones, or can be separately arranged. Since it is used to evaluate the noise cancellation effect, it can not be strictly arranged in the form of an array on the road surface, for example, it can be arranged on the roadside or on one side close to pedestrians or residential population.

[0124] In the present scheme, if it is found that the noise cancellation effect is low, that is, the sound of the vehicle horn is not fully suppressed, the amplitude of the noise cancellation sound information of the noise cancellation speaker can be increased to achieve the purpose of full suppression. On the contrary, if it is found that the sound information obtained by the noise cancellation effect evaluation microphone is the same as the phase of the noise cancellation sound information, it means that over-suppression occurs, and the amplitude of the noise cancellation sound information can be reduced to perform noise cancellation of the vehicle horn sound. ​

[0125] In this scheme, specifically, the noise-cancelling sound information is determined according to the audio information, and the noise-cancelling sound information is emitted by the target loudspeaker to perform noise-cancelling processing, including:

[0126] extracting the frequency, amplitude and phase of the audio information;

[0127] determining the noise-cancelling frequency, noise-cancelling amplitude and noise-cancelling phase of the noise-cancelling sound information according to the frequency, amplitude and phase of the audio information; wherein the noise-cancelling frequency is the same as the frequency of the audio information, the noise-cancelling amplitude is the same as the amplitude of the audio information, and the noise-cancelling phase is opposite to the phase of the audio information;

[0128] emitting the noise-cancelling sound information by the target loudspeaker according to the noise-cancelling frequency, noise-cancelling amplitude and noise-cancelling phase to perform noise-cancelling processing.

[0129] Figure 9 is a noise-cancelling principle schematic diagram provided by the embodiment of the present application. As shown in Figure 9 The ground sound pickup is divided into two types, A type, whistle noise sampling sound pickup, which only monitors the whistle sound of the vehicle and filters the sound waves generated by the paired loudspeaker. The B type sound pickup is a noise-cancelling effect evaluation sampling sound pickup, which listens to the sound of the entire frequency band in the area.

[0130] The waveform characteristics and audio intensity of the sound wave detected by the A type sound pickup at the position of the sound pickup are calculated by the audio processing unit to output a sound wave with opposite waveform and consistent audio intensity, which is emitted by the paired loudspeaker to achieve noise cancellation.

[0131] The B type sound pickup is used for noise-cancelling effect evaluation and full-frequency detection of area sound waves. The sound quality of the evaluation area is further fed back to the loudspeaker. If it is necessary to enhance or weaken the noise-cancelling sound information emitted by the loudspeaker, corresponding control can be performed. In this scheme, in order to avoid abnormal noise-cancelling effect in the area far away from the intersection, the B type sound pickup can be installed in the personnel activity area around the intersection.

[0132] Through such a setting, the noise-cancelling effect can be monitored while noise-cancelling, and the noise-cancelling sound information can be adjusted according to the monitoring result, so as to achieve the purpose of effectively processing noise.
