Detailed Description
The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.
Referring to fig. 1, in order to prevent the occurrence of the vehicle jam accident caused by the misjudgment of the driver, the embodiment provides a vehicle passing prompting method, which is executed by a vehicle-mounted terminal. The vehicle-mounted terminal is respectively in communication connection with an image acquisition device (such as a camera arranged on the current vehicle) and a voice device (such as a loudspeaker).
Referring to fig. 2, the vehicle passage prompting method includes the following steps:
s21: receiving a video signal of a road ahead acquired by the image acquisition device;
preferably, the image acquisition device is arranged in front of the current vehicle. The image acquisition device captures video pictures of a front road in the driving process of the vehicle in real time and transmits the video pictures to the vehicle-mounted terminal.
S22: identifying the size of a passing space contained in a front road according to the video signal;
specifically, the vehicle-mounted terminal identifies a front road surface and a passing space from a video picture based on the existing image processing technology. The so-called traffic space comprises: streets, halls, culverts, passageways between two obstacles, etc. In the present embodiment, the size of the passage space specifically refers to the width of the passage space.
S23: judging whether the current vehicle can smoothly pass through the passing space;
specifically, the width of the passing space is compared with the width of the current vehicle; and if the width of the passing space exceeds the width of the current vehicle and reaches a preset threshold value, judging that the current vehicle can smoothly pass through the passing space. The larger the preset threshold value is, the smoother the vehicle passes through the passing space.
S24: and enabling the voice device to broadcast the judgment result so as to prompt whether the passing space can pass or not.
Specifically, the vehicle-mounted terminal generates a voice signal according to the judgment result and sends the voice signal to the voice device. If the vehicle cannot safely pass through the vehicle-mounted terminal, the content of a voice signal sent by the vehicle-mounted terminal to a voice device in the vehicle timely reminds and warns a driver that the passing space in front of the vehicle is too narrow or the vehicle body is too wide and cannot pass through the vehicle-mounted terminal, so that traffic accidents caused by the fact that the vehicle is clamped are avoided, and driving safety is fully guaranteed; if the vehicle can pass safely as a result of the judgment, the content of the voice signal sent by the vehicle-mounted terminal to the voice device in the vehicle informs a driver that the vehicle can pass through the front passing space smoothly.
Optionally, in another embodiment, the vehicle-mounted terminal is further connected with a head-up display device in a communication manner. Head Up Display (HUD) was used earlier as a flight aid for aircraft and later in automobiles. HUD utilizes the principle of optical reflection, with data projection on the windscreen for the driver can reduce the frequency of looking at the instrument with low head, avoids attention to interrupt and leads to the emergence of traffic accident.
In this embodiment, the vehicle passage prompting method further includes: and enabling the head-up display device to project the judgment result to a front windshield, so that the prompting effect is enhanced.
Specifically, the HUD receives the judgment result sent by the vehicle-mounted terminal and then projects the judgment result to the front windshield, so that a driver is prompted whether the current vehicle can pass through the front passing space or not.
The reason why the judgment result is displayed on the HUD instead of the entertainment center control screen of the vehicle or other display screens is that the attention and the sight of the driver are concentrated in the front direction in the driving process, the driver can observe the judgment result most at the first time through the HUD display, and the judgment result is informed to the driver at the fastest speed, so that the driving safety is improved.
All or part of the steps for implementing the above method embodiments may be performed by hardware associated with a computer program. Based upon such an understanding, the present invention also provides a computer program product comprising one or more computer instructions. The computer instructions may be stored in a computer readable storage medium. The computer-readable storage medium can be any available medium that a computer can store or a data storage device, such as a server, a data center, etc., that is integrated with one or more available media. The usable medium may be a magnetic medium (e.g., floppy Disk, hard Disk, magnetic tape), an optical medium (e.g., DVD), or a semiconductor medium (e.g., Solid State Disk (SSD)), among others.

The processing module 32 identifies the size of the passing space included in the front road according to the video signal; judging whether the current vehicle can smoothly pass through the passing space; and enabling the voice device to broadcast the judgment result so as to prompt whether the passing space can pass or not.
Specifically, the vehicle-mounted terminal identifies a front road surface and a passing space from a video picture based on the existing image processing technology. The so-called traffic space comprises: streets, halls, culverts, passageways between two obstacles, etc. In the present embodiment, the size of the passage space specifically refers to the width of the passage space.
Specifically, the width of the passing space is compared with the width of the current vehicle; and if the width of the passing space exceeds the width of the current vehicle and reaches a preset threshold value, judging that the current vehicle can smoothly pass through the passing space. The larger the preset threshold value is, the smoother the vehicle passes through the passing space.
Specifically, the vehicle-mounted terminal generates a voice signal according to the judgment result and sends the voice signal to the voice device. If the vehicle cannot safely pass through the vehicle-mounted terminal, the content of a voice signal sent by the vehicle-mounted terminal to a voice device in the vehicle timely reminds and warns a driver that the passing space in front of the vehicle is too narrow or the vehicle body is too wide and cannot pass through the vehicle-mounted terminal, so that traffic accidents caused by the fact that the vehicle is clamped are avoided, and driving safety is fully guaranteed; if the vehicle can pass safely as a result of the judgment, the content of the voice signal sent by the vehicle-mounted terminal to the voice device in the vehicle informs a driver that the vehicle can pass through the front passing space smoothly.
Optionally, in another embodiment, the vehicle-mounted terminal is further connected with a head-up display device in a communication manner. Head Up Display (HUD) was used earlier as a flight aid for aircraft and later in automobiles.
