Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
Fig. 1 is a schematic flow chart of a monitoring method for a rear seat in a vehicle according to an embodiment of the present application. It should be noted that the monitoring method for the rear seats in the vehicle according to the embodiment of the present application may be applied to an electronic device, where the electronic device is disposed at the back of the front seats in the vehicle, and the electronic device has a camera, and the camera is used for acquiring images of the rear seats in the vehicle. In the embodiment of the present application, the electronic device may be a hardware device such as a tablet computer with various operating systems, for example, the electronic device may be a rear seat entertainment system, which provides entertainment functions for passengers on the rear seat.
As shown in fig. 1, the monitoring method for the rear row seats in the vehicle includes the following steps:
In this step, steerable camera carries out image acquisition to back row seat in the car according to certain scanning frequency, and the camera can send the image of gathering for electronic equipment when gathering the image to make electronic equipment can obtain the image information that the camera was gathered at present.
102, acquiring pre-designated reference image information; the reference image information is an image of a person sitting normally on a back seat.
Optionally, after the image information currently acquired by the camera is acquired, pre-specified reference image information may be acquired; the reference image information is an image of a person sitting normally on a back seat. Alternatively, before the image information currently acquired by the camera is acquired, the pre-specified reference image information may be acquired. That is, the execution sequence of step 101 and step 102 is not particularly limited, and step 101 may be executed first and then step 102 may be executed, or step 102 may be executed first and then step 101 may be executed, or steps 101 and 102 may also be executed simultaneously.
In the embodiment of the application, when the monitoring function of the electronic equipment for the rear seat in the vehicle is started and it is determined that a person is in the rear seat in the vehicle, the current state of the rear seat in the vehicle is shot through the camera, and the obtained image information is used as the reference image information.
As an example, the electronic device is connected with a vehicle-mounted infotainment system, and when the vehicle-mounted infotainment system receives a starting instruction input by a user, the vehicle-mounted infotainment system can send the starting instruction to the electronic device so as to enable the electronic device to start the monitoring function; the vehicle-mounted infotainment system can provide a touch button for a user to input an opening instruction, or can determine a gesture of the user inputting the opening instruction through a gesture recognition technology.
In addition, in the embodiment of the application, when the monitoring function of the electronic device for the rear seat in the vehicle is turned on, whether a person is in the rear seat can be determined through a person detection device on the rear seat, wherein the person detection device can be a gravity sensor or other detection devices.
And 103, matching the currently acquired image information with the reference image information, and judging whether the position of the person on the back seat is abnormal or not.
Further, after the pre-specified reference image information is acquired, the currently acquired image information may be matched with the reference image information to determine whether the position of the person on the rear seat is abnormal.
As an example, matching the currently acquired image information with the reference image information to determine whether an abnormality occurs in the position of the person on the rear seat includes: acquiring first characteristic information of a person in reference image information; extracting second characteristic information of people in the currently acquired image information; calculating the matching degree between the first characteristic information and the second characteristic information of the person; when the matching degree is larger than a first preset threshold value, determining that the positions of the people on the rear-row seats are normal; and when the matching degree is smaller than or equal to a first preset threshold value, determining that the position of the person on the rear seat is abnormal.
For example, as shown in fig. 2, after determining the reference image information, extracting the feature information in the reference image information, converting the feature information in the reference image into a scanning point, then the electronic device performs feature extraction on the currently acquired figure image information of the back seat, converting the currently extracted feature into a scanning point, comparing the scanning point corresponding to the reference image information with the scanning point corresponding to the figure feature information in the currently acquired figure, when the matching degree between the scanning point corresponding to the figure feature in the currently acquired figure and the scanning point corresponding to the reference image information exceeds a first preset threshold (e.g. 40%), determining that the position of the figure on the back seat is normal, if the matching degree between the scanning point corresponding to the figure feature in the currently acquired figure and the scanning point corresponding to the reference image information is less than or equal to the first preset threshold, and judging that the position of the person on the rear row seat is abnormal. The characteristic information may be the mouth, nose, eyes, head contour, etc. of the person.
As another example, matching the currently acquired image information with reference image information to determine whether an abnormality occurs in the position of a person on a rear seat includes: acquiring a first proportion of a human area in the reference image information; calculating a second proportion of the human area in the currently acquired image information; calculating a difference between the first and second ratios; when the difference value is smaller than or equal to a second preset threshold value, determining that the positions of the people on the rear-row seats are normal; and when the difference value is larger than a second preset threshold value, determining that the position of the person on the rear seat is abnormal.
For example, the total number of the pixel points is determined by extracting the pixel points of the figure outline edge in the reference picture, and the proportion of the total pixel points of the figure outline edge in the reference picture to the total pixel points of the reference image information is determined, and the proportion serves as a first proportion; extracting pixel points of figure outline edges in the currently acquired image, determining the number of the pixel points, and determining the proportion of total pixel points of the figure outline edges in the currently acquired image to the total pixel points in the currently acquired image, wherein the proportion serves as a second proportion; then, calculating a difference value between the first proportion and the second proportion, and determining that the position of the person on the rear seat is normal when the difference value is smaller than or equal to a second preset threshold (such as 40%); and when the difference value is larger than a second preset threshold value, determining that the position of the person on the rear seat is abnormal.
It should be noted that the two examples given above for determining whether the position of the person on the rear seat is abnormal are for the convenience of understanding the present application in the field, and are not to be taken as specific limitations, that is, the determination of whether the position of the person on the rear seat is abnormal may also be realized by other technical means, and the present invention is not limited specifically.
It should be noted that, in an embodiment of the present application, when it is determined that the position of the person on the rear seat is not abnormal, the process may return to step 101, that is, continue to acquire the image information acquired by the camera, and further determine whether the position of the person on the rear seat is abnormal based on the acquired image.
And step 104, if the position of the person on the back-row seat is abnormal, early warning is carried out.
In order to timely remind the rear seats of abnormal conditions so as to guarantee the driving safety of passengers and drivers, in the embodiment of the application, when the electronic equipment determines that the positions of people on the rear seats are abnormal, early warning is performed.
It is understood that when the electronic device determines that the position of the person on the rear seat is abnormal, the electronic device may generate the warning information, and then may perform warning based on the warning information through the electronic device itself, or may transmit the warning information to the external device through the electronic device, so that the external device performs warning based on the warning information. The external device may be a vehicle-mounted infotainment system connected to the electronic device, or a mobile terminal of a driver, or the like.
As an example, the warning information is sent to an alarm module in the electronic device, so that the alarm module performs warning based on the warning information. For example, after the alarm module of the alarm module in the electronic device receives the alarm information, the driver may be informed of the abnormality in the position of the person on the rear seat in a manner of voice or ringing.
As another example, the electronic device establishes a communication connection with an in-vehicle infotainment system in the vehicle and sends the early warning information to the in-vehicle infotainment system based on the communication connection so that the in-vehicle infotainment system can perform early warning based on the early warning information. For example, the electronic device and a vehicle-mounted infotainment system in the vehicle can be connected in a wired or wireless mode, the electronic device sends the early warning information to the vehicle-mounted infotainment system, and after the vehicle-mounted infotainment system receives the early warning information, the vehicle-mounted infotainment system can inform a driver of the abnormal position of a person on a rear seat in a voice playing mode.
As yet another example, a communication connection is established between the electronic device and a mobile terminal of the driver, and the warning information is sent to the mobile terminal based on the communication connection, so that the mobile terminal performs warning based on the warning information. For example, the electronic device establishes a connection with a mobile phone of a driver, when the electronic device determines that the position of a person on a rear seat is abnormal, the electronic device sends the early warning information to the mobile phone of the driver, and the mobile phone sends out a prompt ringing sound for early warning after receiving the early warning information.
In order to view the situation of the rear seats In time, optionally, In this embodiment of the application, as shown In fig. 3, a first communication connection may be established between the electronic device and a Vehicle-mounted infotainment system (In-Vehicle information, abbreviated as IVI) In the Vehicle, a camera is used to record videos of the rear seats In the Vehicle In real time, and the video images recorded In real time are sent to the Vehicle-mounted infotainment system through the first communication connection, so that the Vehicle-mounted infotainment system plays the video images recorded In real time. The first communication connection may be a Wireless communication connection or a wired communication connection, the Wireless communication connection may be, for example, a Wireless Fidelity (WIFI) connection, a Bluetooth (Bluetooth) connection, a fourth generation mobile communication technology 4G, and the wired connection may be, for example, a Low-Voltage Differential Signaling (LVDS) connection, an ethernet connection, and the like.
As an example, a wireless WIFI connection is established between the electronic device and a vehicle-mounted infotainment system in a vehicle, a real-time video stream collected by a camera of the electronic device is transmitted to the vehicle-mounted infotainment system in real time through the WIFI through a User Datagram Protocol (UDP), and the vehicle-mounted infotainment system performs decoding and demonstration through a designated player.
As another example, an ethernet wired connection is established between the electronic device and a vehicle-mounted infotainment system in a vehicle, a real-time Video stream collected by a camera of the electronic device is connected via the ethernet wired connection by an Audio Video Bridge (AVB) protocol to realize real-time transmission of the Video stream to the vehicle-mounted infotainment system, and the vehicle-mounted infotainment system performs decoding and demonstration via a designated player.
In one embodiment of the present application, the electronic device may be plural. The camera in each electronic device can acquire images of the rear-row seat in the shooting area, each electronic device can judge the image shot by the camera, and when one or some electronic devices monitor that the positions of people on the rear-row seat are abnormal, early warning is carried out. Optionally, in an embodiment of the present application, the plurality of electronic devices may further send their respective videos recorded in real time to the in-vehicle infotainment system, so that the in-vehicle infotainment system plays the video images recorded in real time by the plurality of electronic devices. It is understood that, as shown in fig. 4, the monitoring positions of the rear seats in the vehicle may be classified into a rear seat panorama, a rear seat right side, a rear seat left side, and the like. Therefore, the corresponding monitoring view angle of the rear seat in the vehicle can be divided into a rear seat panoramic image and a rear seat single image.
In order to save related consumption, in the embodiment of the application, when the monitoring visual angle of the rear seat in the vehicle is a single image of the rear seat, only a real-time video of a camera in the electronic device at the single side of the back of the front seat in the vehicle needs to be acquired. For example, when a person detection device on a rear seat detects that a person is on the left side of a rear seat in a vehicle, an electronic device on the left side of the back of a front seat in the vehicle monitors the left side position of the rear seat in the vehicle, simultaneously obtains a real-time video of a camera in the electronic device on the left side of the back of the front seat in the vehicle, then transmits the obtained real-time video to a vehicle-mounted infotainment system in a wireless or wired manner, and after receiving a video stream, the vehicle-mounted infotainment system decodes the video stream by a local player of the vehicle-mounted infotainment system, and plays a picture on the left side of the rear seat on an interface of the vehicle-mounted infotainment system according to a specified resolution.
In addition, when the monitoring view angle of the rear seat in the vehicle is a panoramic image of the rear seat, a real-time video of a camera of each electronic device on the back of the front seat in the vehicle needs to be acquired. For example, when the person detection device on the rear seat detects that people are on both the left and right sides of the rear seat in the vehicle, the left electronic device on the back of the front seat in the vehicle monitors the left position of the rear seat in the vehicle, the right electronic device on the back of the front seat in the vehicle monitors the right position of the rear seat in the vehicle, real-time videos of cameras in the electronic devices on both the left and right sides of the back of the front seat in the vehicle are obtained simultaneously, then the obtained real-time videos are transmitted to the vehicle-mounted infotainment system through the wireless or wired mode by the electronic devices, after the vehicle-mounted infotainment system receives the video streams, the received video streams are subjected to interface splicing through an image synthesis technology, and then a panoramic picture of the rear seat is played on the interface of the vehicle-mounted infotainment system according to the designated resolution and the playing mode.
The monitoring method for the rear row seats in the vehicle comprises the following steps: acquiring image information which is currently acquired by a camera and aims at a rear seat in a vehicle; acquiring pre-designated reference image information; the reference image information is an image of a person normally sitting on a back-row seat; matching the currently acquired image information with reference image information, and judging whether the positions of people on the back row seats are abnormal or not; and if the position of the person on the rear-row seat is abnormal, early warning is carried out. According to the method, the rear-row seat is subjected to image acquisition through a camera on the electronic equipment at the back of the front-row seat in the vehicle, the condition of the rear-row seat can be checked in time, and the passenger and the driver can be reminded in time when the position of a person on the rear-row seat is monitored to be abnormal, so that the driving safety of the passenger and the driver is guaranteed; in addition, the electronic equipment with the camera is arranged at the back of the front seat in the automobile, so that the shooting effect of the rear seat can be improved, and the image quality definition of the rear seat is ensured.
In order to check the condition of the rear seats more timely and remind people on the rear seats in time when the positions of the people on the rear seats are abnormal so as to guarantee the driving safety of passengers and drivers, the application also provides another monitoring method for the rear seats in the vehicle, and the method is applied to a vehicle-mounted information entertainment system. The back of the front row seat in the vehicle can be provided with electronic equipment, the electronic equipment is provided with a camera, and the camera is used for collecting images of the rear row seat in the vehicle.
Fig. 5 is a flowchart of another monitoring method for a rear seat in a vehicle according to an embodiment of the present application. As shown in fig. 5, the monitoring method for the rear row seats in the vehicle includes the following steps:
The first communication connection may be a wireless communication connection or a wired communication connection, the wireless communication connection may be, for example, a WIFI connection, a Bluetooth (Bluetooth) connection, a fourth generation mobile communication technology 4G, or the like, and the wired connection may be, for example, a Low Voltage Differential Signaling (LVDS), an ethernet, or the like.
And step 504, early warning is carried out based on the early warning information.
As an example, after the early warning information sent by the electronic device is received, the driver can be informed of the abnormal position of the person on the back row seat in a voice broadcasting mode and/or a text presenting mode, and the driver can pay attention to the checking.
It can be understood that the camera in the electronic device can also record the video in real time and send the video recorded in real time to the vehicle-mounted infotainment system, so that the vehicle-mounted infotainment system can play the video image recorded in real time by the electronic device. As an example, the number of the electronic devices may be multiple, and each electronic device records a video of a corresponding seat in the rear row of the vehicle in real time through a respective camera, and sends the respective video recorded in real time to the in-vehicle infotainment system, so that the in-vehicle infotainment system plays video images recorded in real time by the multiple electronic devices.
