[0041] The present invention is further described in conjunction with the following application scenarios.

[0042] See also Figure 1 , Figure 2 Embodiment, which shows a device for preventing vehicle door opening killing, including a central control module 1, a camera module 2, an infrared detection module 3 and a prompt module 4; wherein the central control module 1 is wirelessly connected with the camera module 2, the infrared detection module 3 and the prompt module 4 respectively;

[0043] The infrared detection module 3 is arranged at the door handle inside the vehicle, and is used to detect whether the door handle is in a blocked state. When it is detected that the door handle is blocked, a first detection signal is transmitted to the central control module 1;

[0044] The central control module 1 is used to receive the first detection signal transmitted by the infrared detection module 3, and transmit a first control signal to the camera module 2 according to the received first detection signal;

[0045] The camera module 2 is arranged inside the front door, and its shooting direction is aimed at the rearview mirror on the same side of the vehicle, and is used to start according to the received first control signal, shoot the reflected image of the rearview mirror, and transmit the reflected image to the central control module 1 in real time;

[0046] The central control module 1 further identifies the danger source based on the acquired reflection image based on the machine vision detection technology to obtain the danger source identification result; when the danger source is identified, a first prompt signal is sent to the prompt module 4; wherein the danger source includes pedestrians and non-motor vehicles;

[0047] The prompt module 4 is used to send corresponding prompt information according to the received first prompt signal.

[0048] The method and device for preventing vehicle door-opening killing proposed by the present invention do not need to be modified for vehicle design and can be adapted to the use of vehicles of different models. A camera is arranged on the inside of the front door of the vehicle to aim at the rearview mirror to capture the reflected image of the side and rear of the vehicle, and pedestrians and non-motor vehicles are identified based on the captured reflected image, so that the situation outside the door can be accurately judged, and corresponding prompts can be given through the obtained pedestrian and non-motor vehicle identification results, which can help remind the occupants to close the door to prevent non-motor vehicles and pedestrians from hitting the door, thereby ensuring the safety of both parties and reducing unnecessary losses.

[0049] An infrared detection module 3 is set at the door handle position on the inner side of the vehicle, which can accurately detect the user's intention to get off the vehicle, and control the operation and standby status of the camera module 2 based on the detection result of the infrared detection module 3, which greatly reduces the power consumption of the equipment, reduces the frequency of battery replacement, and improves the user experience.

[0050] In one scenario, the present invention installs a camera under the inner glass window in front of the car, and ensures that the camera installation position is unobstructed. The camera identifies whether there are non-motor vehicles and pedestrians passing by on the road near the car through the reflected image of the rearview mirror. The door handle inside the car door is connected to the camera through wireless induction. When the door handle senses that it is opened, the door handle transmits the "door open" signal to the central control module 1 through wireless data, and the camera is immediately activated and started; through a large amount of training and recognition of the electric vehicle form, it can accurately detect whether there are non-motor vehicles and pedestrians passing by. When an abnormal situation is detected, the alarm in the car immediately sounds to remind the people in the car to close the door to prevent non-motor vehicles and pedestrians from hitting the door, ensuring the safety of both parties and reducing unnecessary losses.

[0051] Among them, the present invention installs the product in the car to reduce the influence of external factors on the product performance. When installed in the car, a stable identification can be performed through the rearview mirror. If the product is placed on the rearview mirror of the car, it is very likely to be blocked by the door when opening the door and affected by light in different environments such as reflection, dark environment, etc. In addition, installing the product in the car can effectively avoid damage to the product caused by collision and extrusion, and greatly reduce the possibility of component loss.

[0052] Preferably, the device further comprises a display module 5;

[0053] The display module 5 is wirelessly connected to the camera module 2 and is used to display the reflected image when the camera module 2 starts to capture the reflected image.

[0054] Through the setting of the display module 5, the reflected image obtained by the camera can be further displayed to the users in the car. At the same time, when setting the specific position and shooting angle of the camera module 2, the picture obtained by the camera in real time can be displayed in the display module 5, which can be used as a basis for making corresponding adjustments to the position and angle of the camera to ensure the quality of the reflected picture collected by the camera.

[0055] In one scenario, the central control module 1 is a K210 control mainboard (K210 development board), wherein the camera module 2 and the prompt module 4 are functional modules mounted on the K210 control mainboard, that is, the central control module 1, the camera module 2 and the prompt module 4 can be integrated into the K210 control mainboard. The K210 control mainboard is electrically connected to the camera module and the prompt module respectively.

[0056] The K210 is equipped with an open source visual recognition module, which can recognize pedestrians and non-motor vehicles in the reflected image based on the visual recognition model. The visual recognition model can be a trained model in the prior art, and the present invention does not specifically limit this.

[0057] When the K210 mainboard receives the occlusion judgment signal from the infrared detection module 3, the K210 mainboard will transmit the signal to the display screen and the camera, the camera will start working, and the display screen will start to display the camera image on the screen. When non-motor vehicles or pedestrians are detected, the signal will be transmitted to the speaker, and the speaker will sound an alarm to remind people to pay attention to vehicles and pedestrians coming from behind.

[0058] In one scenario, generally, the infrared detection module is in the running (detection) state, and the mainboard is in the sleep / standby state. When the infrared detection module 3 detects that the handrail is blocked, it sends a "1" signal to the K210 mainboard to drive the mainboard to start running. The mainboard further sends a "1" signal (such as a high-level electrical signal) to the camera module to start the camera module to start operating.

[0059] In one scenario, the visual recognition model installed on the K210 mainboard is used to identify whether there are non-motor vehicles, pedestrians, etc. passing by outside the vehicle. The non-motor vehicles and pedestrians behind the door are judged by capturing the reflected image of the rearview mirror through the camera. The pedestrians behind can be seen clearly by mechanical vision just like the driver and passengers look at the rearview mirror, and the human interference factors such as the passengers' lack of concentration and forgetting to observe are reduced, the recognition efficiency is increased, and the safety is ensured. The K210 mainboard is pre-installed with a visual recognition model that can identify pedestrians and non-motor vehicles based on the input image screen. When a pedestrian or non-motor vehicle is identified, the corresponding recognition result can be output. As for the specific algorithm and structure used in the specific visual recognition model, the present invention does not make specific limitations here.

[0060] Preferably, see Figure 3 , Figure 4 , the infrared detection module 3 includes an infrared sensor and a signal transmitter, and a signal receiver is provided on the central control module;

[0061] The infrared sensor is arranged on the door handle on the inner side of the vehicle door to determine whether the door handle is blocked; when it is detected that the door handle is blocked, the infrared sensor controls the signal transmitter to send a first detection signal to the signal receiver of the central control module.

[0062] By setting an infrared sensor, such as an infrared sensing sensor, near the door handle on the inside of the vehicle, with the detection area of ​​the infrared sensor aligned with the door handle position on the inside, when the infrared sensor detects that an object (hand) blocks the door handle, the infrared sensor controls the signal transmitter to send a recognition signal to the central control module, and then the central control module controls the camera module to turn on and perform image acquisition and corresponding recognition according to the received recognition signal. The infrared detection module is installed near the door handle inside the vehicle to accurately identify the intention of the person in the vehicle to open the door, and control the camera to start detection. The camera is controlled to be in standby mode at other times, which greatly reduces the power consumption of the equipment, reduces the frequency of battery replacement, and improves the user experience.

[0063] The infrared detection module 3 and the central control module 1 / camera module 2 are connected wirelessly.

[0064] Preferably, the central control module 1 further includes:

[0065] Based on the machine vision detection technology, the hazard source is identified according to the acquired reflection image to obtain a hazard source identification result, and when the hazard source is not identified, a second prompt signal is sent to the prompt module 4.

[0066] In one scenario, regarding the safety situation outside the vehicle door, the central control module 1 controls the prompt module 4 to issue a prompt sound to remind the user to pay attention to the situation outside the vehicle door based on the result that no pedestrians and non-motor vehicles are identified, so as to improve the user experience.

[0067] Preferably, the prompt module 4 includes a buzzer.

[0068] The buzzer is used to emit a first prompt tone according to the received first prompt signal; and,

[0069] A second prompt tone is emitted according to the received second prompt signal.

[0070] According to different situations of detecting and not detecting pedestrians and non-motor vehicles, different prompt sounds can be set according to needs to remind users in the car.

[0071] Preferably, the prompt module includes an MP3 module; the MP3 module can play corresponding prompt information in a multimedia manner.

[0072] Preferably, see Figure 5 , the camera module 2 includes a camera 21, a telescopic rod 22, a rotating pan / tilt head 23 and a fixed bracket 24;

[0073] The camera 21 is arranged on a rotating pan-tilt platform 23, and the shooting angle of the camera 21 can be adjusted by the rotating pan-tilt platform 23; the rotating pan-tilt platform 23 is fixedly connected to one end of the telescopic rod 22, and the other end of the telescopic rod 22 is fixedly connected to the fixed bracket, and the fixed bracket 24 is fixedly connected under the window on the inner side of the front door of the vehicle.

[0074] In one scenario, with respect to the way in which the camera module 2 is set on the inside of a vehicle door, the present invention further particularly proposes a specific structure of the camera module 2. When installing the camera module 2, the fixing bracket 24 is first fixedly set below the interior glass window (car window) in front of the vehicle by gluing or matching the bracket, wherein the specific position and angle of the camera are adjusted according to the setting angle of the rearview mirror on the same side of the vehicle. First, the length of the telescopic rod 22 is adjusted to adjust the height of the camera so that the horizontal height of the camera can exceed the lower edge of the car window to ensure that the camera has enough space and angle to shoot the reflected image; after completing the height setting, the horizontal angle and vertical angle of the specific lens of the camera are adjusted by adjusting the rotating pan-tilt head 23 according to the relative position of the camera and the rearview mirror, so that the rearview mirror can be within an appropriate range in the reflected image to ensure the effect of reflecting the image and the subsequent visual recognition based on the reflected image.

[0075] By installing the camera module 2 at the inner position of the front door of the vehicle and cooperating with the vehicle rearview mirror to obtain the reflected image of the side and rear of the vehicle, the influence of external factors on the performance of the product is reduced. It can avoid the situation that the traditional product is placed on the rearview mirror of the car, which is likely to be blocked by the door when the door is opened and affected by the light in different environments such as reflection, dark environment, etc. In addition, installing the product in the car can effectively avoid damage to the product caused by collision and extrusion, and greatly reduce the possibility of component loss.
