Problems solved by technology

However, when there are multiple passengers talking at the same time in the car or the sound in the car is noisy, the processing method of the existing microphone array will be interfered by the sound sources in different positions, and it is often difficult to judge the position of the speaker of the video call, which makes it difficult to adjust the camera to the right position. The position of the current speaker, which has a greater impact on the user's video call experience

Embodiment 1

[0040] An embodiment of the present application provides a method for in-vehicle video calling, which will be described in detail below with reference to the accompanying drawings.

[0041] see figure 1 , which is a flow chart of a method for in-vehicle video calling provided in Embodiment 1 of the present application.

[0042] The method comprises the steps of:

[0043] S101: If multiple voiceprint features are detected, perform a prompt operation, the prompt operation is used to prompt that the number of speakers in the car is kept as 1.

[0044] When the user in the car needs to use the video call function, the user wakes up the video call system, and the system can be controlled by a soft switch on the display system or by voice, which is not specifically limited in this application.

[0045] When the video call system is started, the microphone array starts to collect the voice of the speaker in the car. At this time, the collected sound may not only include the voice o...

Embodiment 2

[0070] Based on the method described in Embodiment 1, the implementation process of in-vehicle video calling will be specifically described below with reference to the accompanying drawings.

[0071] see figure 2 , which is a flow chart of the in-vehicle video call process provided by Embodiment 2 of the present application.

[0072] The video call process includes the following steps:

[0073] S201: The user initiates a call request.

[0074] The user wakes up the video call system, including the user actively wakes up the video call system or the user passively wakes up the video call system due to being called. The system can be controlled by a soft switch or voice on the display system, which is not specifically limited in this application.

[0075] S202: Collect sounds in the vehicle space.

[0076] In the form of multi-channel audio input, the sound in the vehicle space is continuously collected in real time during the process from the user's call request to the end ...

Embodiment 3

[0102] Based on the vehicle-mounted video calling method provided in the above embodiments, the embodiment of the present application further provides a vehicle-mounted video calling system, which will be described in detail below with reference to the accompanying drawings.

[0103] see image 3 , which is a schematic diagram of a vehicle-mounted video call system provided in Embodiment 3 of the present application.

[0104] like image 3 As shown, the system 300 in the embodiment of the present application includes: a voiceprint analysis module 301 , a sound source localization module 302 , a controllable camera module 303 , a microphone array 304 , a network communication module 305 and an in-vehicle display system 306 . Wherein, the voiceprint analysis module 301 and the sound source localization module 302 can be integrated on the system host.

[0105] The voiceprint analysis module 301 supports the voiceprint analysis function, can extract the voiceprint features of th...

Abstract

The invention provides a vehicle-mounted video call method, and the method comprises the steps: carrying out the prompt operation if a plurality of voiceprint features are detected, wherein the promptoperation is used for prompting that the number of speakers in a vehicle is 1; if the number of the voiceprint features is changed to 1, determining position information corresponding to the existingvoiceprint features; and controlling the working position of the camera according to the position information. According to the invention, the camera can be kept right opposite to the current speakerwithout being interfered by sound sources at other positions during video call, and after the current speaker finishes speaking, the position of a new speaker can be re-judged and the position of thecamera can be re-adjusted, so that a good in-vehicle video call effect is achieved, and the in-vehicle video call experience of a user is improved. The invention further provides a vehicle-mounted video call system.

Description

technical field [0001] The present invention relates to the technical field of video calls, in particular to a method and system for in-vehicle video calls. Background technique [0002] At present, the network connection and intelligence of automobiles have become more and more popular. The vehicle infotainment system can keep the vehicle connected to the network through the TBOX 4G network to realize the network connection function between vehicles. The information processing capabilities of automotive infotainment systems are becoming more and more powerful, making it possible to run more applications in infotainment systems; at the same time, with the development of lightweight technology for high-performance display screens, the application of in-vehicle display systems in vehicles There are more economical solutions. The above two factors combined with the network communication system make it possible to implement video calls on the car infotainment system. [0003] ...
