Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments.

Fig. 1 shows a schematic block diagram of an in-vehicle conferencing system 100 according to an embodiment of the invention. As shown in fig. 1, the in-vehicle conference system 100 may include: controller 110, first camera 120, second camera 130, microphone 140, speaker 150, and positioning module 160.

Illustratively, the controller 110 is operable to output a control signal in response to the conference signal. The conference signal includes seat information of conference participants. For example, the controller 110 may receive a conference signal from a user. In particular, when a user joins a conference, a corresponding conference signal may be sent to the controller 110. The controller 110 may be implemented by using electronic components such as a comparator, a register, and a digital logic circuit, or by using processor chips such as a single chip, a microprocessor, a Programmable Logic Controller (PLC), a Digital Signal Processor (DSP), a Field Programmable Gate Array (FPGA), a Programmable Logic Array (PLA), and an Application Specific Integrated Circuit (ASIC), and peripheral circuits thereof. When the controller 110 receives the conference signal, a corresponding control signal may be output based on the seat information of the conference participant in the conference signal. The seat information of the conference participants comprises the seat numbers of the users who join the conference in the vehicle. The first camera 120 may be used to turn on and capture images of the front row of the vehicle according to the control signal. Wherein the front row comprises a driving position and a copilot position. For example, the first camera 120 may be disposed at any position in the front row that does not obstruct the driving line of sight. The first cameras 120 may be two for capturing images of the driver in the driving seat and capturing images of the passenger in the passenger seat, respectively. When the meeting signal received by the controller 110 indicates that the user at the driving position joins the meeting, the controller 110 may output a control signal for controlling the first camera 120 for capturing the image of the driver to be turned on. Thereby, the first camera 120 starts to capture an image of the driver of the driving seat. The second camera 130 may be used to turn on and collect images of the rear row of the vehicle according to the control signal. By reading the foregoing technical solution of how the first camera 120 operates in response to the control signal, the operating principle of the second camera 130 can be understood, and is not described herein again for brevity. The number of the second cameras 130 may also be multiple. The microphone 140, speaker 150, and positioning module 160 may also be electrically connected to the controller 110, respectively. The microphone 140 and the speaker 150 may be provided at each seat of the vehicle, respectively. That is, a microphone 140 and a speaker 150 are provided at each seat of the vehicle. The positioning module 160 may receive control signals from the controller 110. When the conference signal received by the controller 110 indicates that users, for example, seat numbers 2 and 3, join the conference, the controller 110 may output corresponding control signals at this time. Based on the control signal, the positioning module 160 may control the microphones 140 and the speakers 150 at the seat numbers 2 and 3 to be turned on to capture and play the voice signals at the two seats. While the positioning module 160 may also control the microphones 140 and speakers 150 at other seat numbers to be turned off.

Therefore, the camera at the position of the conference participant can be independently opened according to the position requirement of the conference participant, so that the privacy disclosure of the conference participant to other environments or people in the vehicle is ensured. Meanwhile, the microphones 140 at other positions in the car can be closed according to the position positioning of the conference participants, and only the microphone 140 at the position of the conference participant is kept open, so that the definition of video call is ensured, and the sound interference of other positions and the environment around the conference participant is avoided. In addition, the loudspeaker 150 at the position can be positioned and opened independently according to the position of the conference participant, so that the privacy of the conference participant is ensured, and the interference to other passengers in the vehicle can be prevented. The good audio input environment and the good audio receiving scene of the positions of the conference participants are provided, and the good privacy and the good intelligent experience of the video conference are improved.

For example, the first camera 120 may be disposed on left and right a-pillar garnishes of a vehicle. The second camera 130 may be disposed on left and right B-pillar garnishes of the vehicle. Alternatively, the first camera 120 and the second camera 130 may be disposed on the left and right a pillar garnish and the left and right B pillar garnish, respectively, in a welded, embedded, or the like manner.

Therefore, the acquired images of the conference participants are the body front images above the elbows, and the imaging effect of the camera is improved.

Illustratively, the speaker 150 may be disposed in a seat headrest corresponding to the seat. Thus, interference with passengers at other positions when the speaker 150 emits sound can be minimized.

Illustratively, the controller 110 may be further configured to generate a focus adjustment signal according to a picture sharpness requirement of the conference, so that the first camera 120 and/or the second camera 130 automatically adjust the corresponding focus in response to the focus adjustment signal. For example, the user may make a custom setting for the screen definition of the conference. For the image definition requirement sent by the user, the controller 110 may calculate the focal length of the corresponding camera according to the algorithm of the video imaging image definition requirement, and generate a corresponding focal length adjustment signal accordingly. The focal length adjusting signal can include an effective focal length of the camera which can meet the requirement of image definition. According to the focal length adjustment signal, the first camera 120 and the second camera 130 may automatically adjust the corresponding focal lengths. It will be appreciated that no adjustment is required for the focal length to meet the sharpness requirements of the picture.

Therefore, the requirements of different users on the definition of the conference picture can be met, and the use experience of the users is improved.

Illustratively, the in-vehicle conference system 100 may further include: a driver's seat display screen, a copilot display screen and other position display screens. The driving position display screen is arranged on a front operation table of the vehicle, the driving position display screen comprises an instrument display area and a conference display area, the instrument display area is used for displaying instruments frequently, and the conference display area is used for responding to the operation of a user to display a conference scene when the vehicle is in a static state; the copilot display screen and the other position display screens are respectively used for responding to the operation of a user and displaying a conference scene; wherein the conference scene includes a user image at a current seat, user images of conference participants at other seats, and/or user images of remote conference participants.

In one embodiment, the meeting display area of the driver's seat display screen is turned off by default during driving for driving safety. Only when the vehicle is in a static state, the conference display area in the driving position display screen can start all functions of the video conference scene in a suspicious mode. The driver's seat display screen middle number can include the instrument display area, no matter what state the vehicle is in, the instrument display area all is used for showing the instrument. For the copilot display screen, an entertainment display area and a conference display area may be included. The entertainment display area is used for providing entertainment scenes for passengers in the passenger seat, and the conference display area is used for providing conference scenes for passengers in the passenger seat. The other-position display screen comprises a meeting display area used for providing meeting scenes for passengers at other positions except the driving position and the auxiliary driving position. The conference scene may include, among other things, images of the passenger currently participating in the conference at the seat, images of conference participants at other seats in the same vehicle, and images of users remotely participating in the conference. Alternatively, the display screen at the conference participant location may be turned on by default and display images or conference content. Or, the conference participant can also manually close or turn off the display screen at the corresponding position by voice according to the requirement of the conference participant on the display of the video image content.

Therefore, the driving safety is ensured, and passengers at all positions in the vehicle can watch meeting scenes and meeting contents. Namely, the personal safety of the user is guaranteed, and meanwhile the video conference can be normally carried out.

Alternatively, the other position display screen may be embedded in the ceiling of the vehicle, and the other position display screen is disposed opposite to the ceiling. The other position display screen is also used for responding to the meeting signal and automatically turning over the preset angle so as to enable the other position display screen to face the user.

In this embodiment, the other-position display screen may be disposed on the ceiling of the corresponding position in an embedded manner. The screens of the other position display screens are disposed toward the ceiling. If the passenger at the corresponding position participates in the conference, the corresponding conference signal can be generated, and at this time, the display screen at the other position can be turned over by a preset angle, for example, 90 degrees, to be opened in response to the conference signal, so that the screen faces the user and the video image and the conference content are displayed to the user. It can be understood that the conference participants can also manually or voice close the display screens at other positions according to the requirements of the conference participants. In the process, the display screen at other positions can be automatically turned by 90 degrees to be embedded and attached to the ceiling again.

Therefore, the users at other positions can be ensured to watch the conference scene and the conference content, the phenomenon that the display screens at other positions occupy too much space in the vehicle when the users at other positions do not participate in the conference can be avoided, the activity of the users is not influenced, and the use experience of the users is improved.

Illustratively, the in-vehicle conferencing system 100 may also include a reading light. A reading light may be provided on the ceiling of the vehicle above each seat of the vehicle or behind the seat back of the seat in front of it for providing illumination to the user on the seat. For example, the reading light may be a Light Emitting Diode (LED). Optionally, the passenger may also manually adjust the brightness of the reading light as desired.

Therefore, the passenger can turn on the reading lamp when the light in the vehicle is insufficient, so that the activities such as reading and the like can be carried out in the vehicle. The passenger is guaranteed to be free from activities such as reading. Meanwhile, the existence of the reading lamp can also ensure that passengers as conference participants can form high-definition images when carrying out a video conference.

Illustratively, the controller 110 is further configured to receive the in-vehicle ambient light signal collected from the first camera 120 and/or the second camera 130, so as to control the on, off and/or dimming level of the reading lamp located in the same seat as the first camera 120 and/or the second camera 130 based on the in-vehicle ambient light signal.

For example, photosensitive sensors are disposed in the first camera 120 and the second camera 130, and are used for detecting the brightness of the environment in the vehicle in real time. Corresponding in-vehicle ambient light signals may be generated for different levels of brightness. The first camera 120 and the second camera 130 transmit the in-vehicle ambient light signal to the controller 110 after generating the same. The controller 110 may control the reading lamp located at the same position as the first camera 120 or the second camera 130 to be turned on, turned off, or turned on or turned off based on the received in-vehicle ambient light signal.

Therefore, automatic opening and closing of the reading lamp and automatic brightness adjustment can be achieved, manual operation of passengers is not needed, and use experience of users is improved.

Illustratively, the in-vehicle conferencing system 100 may also include a timing module, a temperature acquisition module, and a multifunction seat. Specifically, the timing module is configured to perform a timing operation to generate a corresponding time signal and send the time signal to the controller 110, where the timing operation starts from the beginning of the conference and is completed when the conference is finished. The temperature acquisition module is used for acquiring temperature signals in the vehicle and sending the temperature signals to the controller 110; the controller 110 is further configured to generate corresponding function signals based on the different time signals and/or temperature signals; a multifunction seat for performing a corresponding function in response to a different function signal from the controller 110, wherein the corresponding function includes one or more of the following functions: heating, ventilating, and massaging.

For example, the timing module may be a timer. The timing module may send a time signal corresponding to the time counted by the timing module to the controller 110 in real time. The controller 110 determines whether the duration of the conference exceeds a specific time threshold according to the received time signal to generate a corresponding function signal. Alternatively, the specific time threshold may be preset empirically, or may be customized by the conference participants during the conference. For example, the specific time threshold may be 30 minutes. When the controller 110 receives the time signal indicating that the meeting has been conducted for 30 minutes, the controller 110 may control the multifunction seat to turn on the massage mode to massage the passenger in the seat. It is understood that the passengers on the multifunction seat with the massage mode activated are conference participants. In other words, if the passenger is not a conference participant, the multifunction seat will not turn on the massage mode.

For another example, the in-vehicle conferencing system 100 may also include a temperature acquisition module. The temperature acquisition module can be a temperature sensor, and can be arranged at any reasonable position such as a ceiling of a vehicle and the like for acquiring temperature signals in the vehicle. The temperature acquisition module transmits the acquired temperature signal to the controller 110. The controller 110 may determine whether the temperature in the vehicle is lower than the minimum temperature threshold or higher than the maximum temperature threshold according to the received temperature signal to generate a corresponding function signal. If the received temperature signal is higher than the maximum temperature threshold, the controller 110 controls the multifunction seat to perform a ventilation function. If the received temperature signal is below the minimum temperature threshold, the controller 110 may control the multifunction seat to perform a heating function.

Therefore, the conference participants can be ensured to be in a comfortable environment in the conference process, the conference quality can be ensured, and the use experience is improved.
