[0062] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention.

[0063] In the prior art, in-car screen projection usually adopts wired connection, which limits the mobility of the operating mobile phone and causes inconvenience to users. Wireless connection requires manual operation and permission authentication, and the operation steps are cumbersome and the connection efficiency is low.

[0064] In order to solve the problems in the prior art, this embodiment provides a WiFi screen projection method, through which a fast network connection between a vehicle-mounted screen projection device and a screen projection control terminal can be realized, thereby realizing vehicle-mounted screen projection. In the specific implementation, first, the vehicle-mounted control terminal sends a screen projection broadcast; then, receives a screen projection request fed back by the screen projection control terminal; further receives the face image obtained by the image acquisition device, and performs WiFi connection authority authentication on the face image; if the WiFi connection authority authentication passes, then establishes a screen projection link between the vehicle-mounted control terminal and the screen projection control terminal; finally, obtains the screen projection data, and projects the screen projection data based on the screen projection link. This application uses facial image recognition to quickly authenticate and connect to the network, thereby realizing vehicle-mounted screen projection. Through facial recognition, a connection can be established efficiently and quickly, which brings great convenience to users.

[0065] For example, first, the vehicle control terminal sends a screen projection broadcast; then, it receives the screen projection request fed back by the screen projection control terminal; further, it receives the face image obtained by the image acquisition device, and performs WiFi connection authority authentication on the face image; if the WiFi connection authority authentication is passed, then a screen projection link is established between the vehicle control terminal and the screen projection control terminal; finally, the screen projection data is obtained, and the screen projection data is projected based on the screen projection link. This application uses facial image recognition to quickly authenticate the network connection, and then realizes vehicle-mounted screen projection. Through facial recognition, the connection can be established efficiently and quickly, which brings great convenience to users.

[0066] Exemplary Methods

[0067] This embodiment provides a WiFi screen projection method, which can be applied to a WiFi screen projection device. Figure 1 As shown, the method includes:

[0068] Step S100: Send screen projection broadcast.

[0069] In this embodiment, the user first clicks the screen projection button on the vehicle control terminal, and the vehicle control terminal sends a screen projection broadcast. For example, click the screen projection on the vehicle screen, and the vehicle screen sends a broadcast via Bluetooth. Bluetooth broadcasting is a short-range wireless communication method that allows Bluetooth devices to send information to the outside world through broadcast data packets without establishing a connection with other devices. Bluetooth broadcasting uses the low-power Bluetooth protocol and can operate under energy-saving conditions, which is particularly important for devices that need to run for a long time and rely on battery power. Among them, Bluetooth devices realize data transmission by sending broadcast data packets, which can carry various information, such as device name, UUID (universally unique identifier), sensor data, etc. Bluetooth broadcasting uses low-power technology, which helps to extend the battery life of the device, and Bluetooth broadcasting has good compatibility and is widely used in a variety of devices. Through the broadcast mechanism, Bluetooth devices can be quickly discovered and identified by other devices, improving communication efficiency.

[0070] Step S200: receiving a screen projection request fed back by a screen projection control terminal.

[0071] In this embodiment, after the screen projection control terminal receives the screen projection broadcast sent by the vehicle control terminal, the user clicks the screen projection button on the screen projection control terminal to send a screen projection request feedback to the vehicle control terminal, so as to further establish a screen projection link. In the specific implementation, before receiving the screen projection request feedback from the screen projection control terminal, the image acquisition device and WiFi are automatically turned on to obtain facial images and sound data, etc.

[0072] Step S300: receiving a facial image acquired by an image acquisition device, and performing WiFi connection authority authentication on the facial image.

[0073] In this embodiment, the facial image captured by the image acquisition device connected to the vehicle control terminal is authenticated to confirm whether there is permission to connect to WiFi. The image acquisition device can be a camera or other device that can capture images and sounds. By timely capturing facial images through the image acquisition device and timely performing authorization authentication, a projection link between the vehicle control terminal and the projection control terminal is established, which greatly improves the connection efficiency between the vehicle control terminal and the projection control terminal. The operation steps are simple and convenient, which greatly improves work efficiency and brings convenience to users.

[0074] Step S400: If the WiFi connection authority authentication is passed, a screen projection link is established between the vehicle-mounted control terminal and the screen projection control terminal.

[0075] In this embodiment, if the facial image recognition is passed, the WiFi is connected, and a screen projection link is established between the vehicle control terminal and the screen projection control terminal. In the specific implementation, a screen projection link is established between the vehicle screen and the mobile phone, or a screen projection control terminal such as iPad. When the permission authentication is passed and the screen projection link is established, the screen projection display can be performed through the screen projection link. For example, the screen of a mobile phone or iPad and other devices can be projected and displayed through the vehicle screen, and the user can directly operate through the vehicle screen.

[0076] Step S500: Acquire screen projection data, and project the screen projection data based on the screen projection link.

[0077] In one implementation, after the projection link is established, the projection data can be received and the projection data can be displayed through the projection link. In the specific implementation, after the projection link between the vehicle control terminal and the projection control terminal is established, the projection control terminal sends the projection data to the vehicle control terminal, and the vehicle control terminal displays the projection data. The user can also directly operate the application of the projection control terminal through the vehicle control terminal, such as navigating directly through the vehicle screen, playing videos, etc., which brings great convenience to the user.

[0078] In one implementation, NFC is used for network configuration, and the vehicle-mounted control terminal and the projection control terminal are connected to realize projection. In the specific implementation, the communication link between the vehicle-mounted control terminal and the projection control terminal can be quickly established through NFC network configuration. The traditional network configuration method has problems such as low network configuration success rate, cumbersome steps, and long time consumption, which seriously affects the user experience. Therefore, the use of NFC network configuration technology is a more convenient and efficient network configuration method. It brings great convenience to users by simplifying the network configuration process and improving the network configuration success rate. NFC is a near-field communication technology. Near-field communication is a short-range high-frequency wireless communication technology based on wireless radio frequency identification technology. It has the characteristics of non-contact, that is, data transmission can be achieved without physical contact, and high security, that is, multiple encryption and identity verification mechanisms are used to ensure the security of data transmission. Near-field communication has a high degree of security. It uses multiple encryption and identity verification mechanisms to ensure that only authorized devices can communicate and the transmitted data is confidential, which is particularly important for applications involving sensitive information. Therefore, using NFC for network configuration can not only achieve efficient and fast network configuration but also ensure the security of network configuration, ensuring that only authorized devices can connect, that is, establishing a screen projection link between the vehicle-mounted control terminal and the screen projection control terminal.

[0079] In one implementation, the Bluetooth signal strength and the WiFi signal strength are obtained, and the position of the projection control terminal is determined based on the Bluetooth signal strength and the WiFi signal strength; it is determined whether the projection control terminal is within a preset range; if the projection control terminal is within the preset range, the Bluetooth device is determined. In the specific implementation, dual positioning is used by Bluetooth and WiFi, and it is confirmed as near field to achieve device discovery and establish connection.

[0080] In one implementation, the gesture image captured by the image acquisition device is obtained, and the gesture image is matched with the gesture in the preset gesture image database; if the gesture image is successfully matched with the gesture in the preset gesture image database, a projection link between the vehicle control terminal and the projection control terminal is established. In the specific implementation, after the gesture image is obtained, it is compared with the gesture in the preset gesture database. If the corresponding gesture is matched, it indicates that there is permission to connect to the network, and then the projection link between the vehicle display terminal and the projection display terminal is quickly established. For example, if the preset gesture is "OK", then if the "OK" gesture is extracted from the image captured by the image acquisition device, it indicates that there is corresponding permission to connect, that is, the user makes an "OK" gesture in front of the camera bound to the vehicle screen, the camera captures the gesture, and then matches it with the custom gesture in the preset gesture image database. If the match is successful, the projection link between the vehicle control terminal and the projection control terminal is quickly established. Through gesture images, the projection link between the vehicle control terminal and the projection control terminal can be quickly established. The operation steps are simple and convenient, which can effectively improve the network efficiency of vehicle projection.

[0081] In one implementation, the sound information collected by the image acquisition device is obtained, and the sound information is matched with the sound in the preset corpus; if the sound information matches successfully, a projection link is established between the vehicle-mounted control terminal and the projection control terminal. Voice network configuration technology converts information such as the SSID (service set identifier) ​​and password of the WiFi network into sound signals through a specific sound wave sequence, and then plays these sound signals through a mobile phone or other sound-emitting device. After receiving these sound signals, the smart device uses a built-in microphone to record, and decodes the sound signals through an internal algorithm library to restore the original SSID and password information, thereby realizing the network configuration of the device. Through voice network configuration, users do not need to manually enter complex SSIDs and passwords, but only need to use voice to complete the network configuration of the device, which greatly simplifies the operation process. Voice network configuration technology can quickly complete the network configuration of the device and improve the user experience.

[0082] In one implementation, electromagnetic induction network distribution is used. In specific implementation, the induction technology network distribution reduces the steps and time of network distribution and improves the user experience.

[0083] In one implementation, the vehicle-mounted screen camera recognizes faces and nearby mobile phones, uses Bluetooth and WiFi dual positioning to confirm that they are near-field to achieve device discovery, recognizes faces through the camera to confirm that WiFi can be connected, performs two-way authentication between the vehicle-mounted and mobile phone ends, and confirms screen projection.

[0084] In one implementation, third-party screen projection software is installed on the vehicle control terminal and the screen projection control terminal, and the user uses the third-party software to achieve wireless connection between the vehicle control terminal and the screen projection control terminal. For example, the third-party screen projection software is usually started on the mobile phone, and matched with the car through Bluetooth or WiFi, to establish a screen projection link between the vehicle control terminal and the screen projection control terminal, thereby achieving screen projection on the vehicle terminal.

[0085] In one implementation, a fingerprint collection device is installed on the vehicle control terminal, and the user's fingerprint is directly obtained through the fingerprint collection device, and the screen projection link is directly connected, which is efficient and convenient. Among them, the fingerprint collection device can be an optical fingerprint collector, a capacitive / inductive fingerprint collector, or a bio-radio frequency fingerprint collector. The optical fingerprint collector has a long service life and is cheap, but has high requirements for the cleanliness of the fingers. For example, dirty fingers and dry fingers have covers attached to the surface, which will affect the recognition accuracy of the fingerprint image, and the adaptability to the environment such as temperature is poor. Compared with the inductive fingerprint collector, the capacitive fingerprint collector provides better image quality in a larger operating range. The bio-radio frequency fingerprint collector has a high pass rate for difficult fingers such as sweaty fingers, strong anti-counterfeiting fingerprint ability, and the recognition principle only reacts to the human dermis, which fundamentally eliminates the problem of artificial fingerprints. At the same time, the bio-radio frequency fingerprint collector can be used in particularly cold conditions or hot areas, and has significant superior performance. Through various fingerprint collection devices, permission authentication can be carried out efficiently and quickly, and then the projection link between the vehicle control terminal and the projection control terminal can be established. In order to improve the accuracy and reliability of fingerprint recognition, higher resolution sensors and collection areas are used. In order to improve the service life and stability of the equipment, more advanced materials and processes are used, as well as more complete protection measures.

[0086] In one implementation, a palmprint collector can also be installed on the vehicle-mounted control terminal, and the authority authentication is performed by collecting palmprints, and a projection link is established between the vehicle-mounted control terminal and the projection control terminal. Since the palmprint collector captures the texture information of the palm through a high-precision sensor, this information has a high degree of uniqueness and stability, and is therefore widely used in fields such as identity authentication, security monitoring, and access control. The use of palmprint authentication has the following advantages: high precision, the palmprint collector uses high-precision sensors and advanced image processing technology to accurately capture the texture information of the palm; high stability, the palmprint features have a high degree of stability and uniqueness, and are not easily disturbed by external factors, so the palmprint collector has a high recognition accuracy rate; easy acceptance, the palmprint collection process is simple and fast, easy for users to accept, and the palmprint information is not easy to be forged or tampered with; low cost, compared with other biometric technologies such as iris recognition, the cost of palmprint collection equipment is relatively low, and it is easier to popularize and promote.

[0087] In one implementation, a wired screen projection method can also be used. When the requirements for screen projection are relatively high, a wired screen projection method is usually used for connection. The device is directly connected to the vehicle-mounted control terminal through HDMI, VGA and other cables to achieve transmission and display of screen content. Through this wired connection method, a relatively stable communication link can be established and is not affected by the network environment, but the operation is relatively cumbersome and requires a physical connection. Therefore, this method is only used in special circumstances, and the wireless connection method listed in this application is preferred.

[0088] This embodiment provides a WiFi screen projection method, which can be applied to a screen projection control terminal. The method includes: receiving a screen projection broadcast sent by a vehicle-mounted control terminal; sending a screen projection request to the vehicle-mounted control terminal; and sending screen projection data to the vehicle-mounted control terminal.

[0089] In the specific implementation, after the vehicle control terminal sends the screen projection broadcast, the screen projection control terminal will scan and receive the screen projection broadcast, and then the screen projection control terminal sends a screen projection request to the vehicle control terminal, and the image acquisition device connected to the vehicle control terminal starts to collect face images and sound images, etc., and establishes a screen projection link between the vehicle control terminal and the screen projection control terminal by performing face image authentication, sound image authentication, gesture image authentication, etc. After the link between the vehicle control terminal and the screen projection control terminal is established, the screen projection data can be sent to the vehicle control terminal for screen projection display. In this application, face recognition, gesture recognition, sound recognition, NFC connection, etc. are used, and these more intelligent network distribution methods can reduce the operating steps in the vehicle screen projection process, thereby improving the efficiency of vehicle screen projection.

[0090] The beneficial effect of the present invention is that by adopting network configuration methods such as face recognition, gesture recognition, voice recognition, NFC, etc., a screen projection link between the vehicle-mounted control terminal and the screen projection display terminal can be established efficiently and quickly. The operation method is simple and convenient, and the efficiency of vehicle-mounted screen projection is effectively improved.
