Description

Technical Field

[0001] This invention relates to the field of vehicle driving action monitoring technology, and in particular to a driving warning method and system based on vehicle driving action recognition. Background Technology

[0002] With the increasing number of cars on the road, people are paying more and more attention to driving safety, especially since most mid-to-high-end and new energy vehicles are equipped with autonomous driving or cruise control functions. If an accident occurs with these vehicles, it is often difficult to understand the driver's actual driving situation without sufficient vehicle driving data and driver operation records. Determining whether the accident was caused by a malfunction in the vehicle itself or by driver error is also difficult. Therefore, various driving monitoring products have emerged on the market that monitor whether the driver is pressing the accelerator or the brake pedal. These products mostly use cameras to record the driver's foot movements. After an accident, the video recordings are reviewed to determine the actual driving situation at the time of the accident. While these types of driving monitoring products have initially solved the problem of recording drivers' foot movements, every driver wants to avoid traffic accidents, not just rely on video evidence after an accident. Furthermore, existing foot pedal monitoring products on the market are independent recording devices that only operate when the vehicle is started. This leads to uncertainties in event and time recording, making it difficult to guarantee consistency between the recorded driving time and the actual accident time. Even memory card malfunctions can prevent the determination of accident liability. They also cannot identify the accuracy of the driver's actions based on the current driving conditions, nor can they pre-set recognition conditions for foot movements to determine if the driver's actions match the current driving scenario. Finally, they cannot issue early driving safety warnings to the driver. Summary of the Invention

[0021] The method further includes: when identification signal six, identification signal five, and identification signal two are identified simultaneously, and the acquired vehicle status data matches the preset driving event database parameters, the preset driving event database parameters are invoked to issue an audio and visual warning to the driver.

[0048] The technical solution of the present invention will be further described below with reference to the accompanying drawings, but the present invention is not limited to these embodiments.

[0049] Example 1

[0050] like Figures 1 to 3As shown, this invention proposes a driving warning method based on vehicle driving action recognition. The method includes: acquiring images of the vehicle control pedals; acquiring images of the accelerator and brake pedals directly from a camera installed under the steering wheel dashboard in neutral position; transmitting the acquired images to an event recording and warning processing device 4; the event recording and warning processing device 4 having preset brake pedal recognition areas and accelerator pedal recognition areas; and the driver being able to drag the preset brake pedal recognition areas and accelerator pedal recognition areas to corresponding positions on the vehicle control pedal images to complete the setting of the brake pedal recognition areas and accelerator pedal recognition areas.

[0051] Furthermore, since different drivers wearing different shoes may interfere with recognition, the event recording and warning processing device 4 can be customized with different brake pedal and accelerator pedal depressing states. This can be achieved by capturing images of different foot positions or different shoes to preset pedal depressing states, thereby enhancing image recognition capabilities. Preferably, the OpenCV corner feature point extraction and matching algorithm is used for image recognition.

[0052] When the brake pedal is detected to be depressed in the brake pedal recognition area, the vehicle control pedal status recognition module 1 sends out a recognition signal.

[0053] When the accelerator pedal is detected to be pressed in the accelerator pedal recognition area, the vehicle control pedal status recognition module 1 sends out recognition signal 2.

[0054] It acquires and identifies images inside the vehicle, and when it detects that there are people inside the vehicle, it sends out an identification signal. The camera with a millimeter-wave sensor combined with Azcom's proprietary algorithm can detect the activities of people inside the vehicle.

[0055] The system acquires and identifies images in front of the vehicle. When movement of the image in front relative to the vehicle is detected, an identification signal is emitted. The system identifies images in front of the vehicle through motion detection and human detection. Motion detection is a signal emitted by the camera based on changes in the pixels of the monitored image. Human detection is a signal emitted by an intelligent algorithm based on the identification and analysis of the image within the frame.

[0056] The system acquires and identifies sounds emitted from inside the vehicle. When the identified sound matches a preset sound condition, it issues an identification signal five. The preset sound condition is set using speech synthesis technology. For example, if the preset sound condition is "brake brake", the corresponding identification signal five is issued. As long as the sound matches the preset sound condition, the identification signal is triggered. Since the preset sound condition is limited, identification is only required for the preset sound condition, avoiding the waste of system resources and impact on operating speed caused by using speech recognition technology.

[0057] Acquire vehicle status data and send out identification signal six. The vehicle status data includes battery power, vehicle speed, brake status, accelerator status, turn signal status, high and low beam status, seat belt status, and handbrake status.

[0058] When any one or more of the identification signals 1, 2, 3, 4, and 5 are received, the received identification signal and the start time of its transmission are recorded, and a timer is started until no more identification signals are received. The duration is recorded, and the vehicle control pedal image, the vehicle interior image, the vehicle front image, and the sound are stored as a data association based on time. For example, if the time of the vehicle control pedal image is 10:01:03, the time of the vehicle interior image is 10:02:06, and the time of the vehicle front image is 10:00:04, then the vehicle control pedal image, the vehicle interior image, and the vehicle front image are uniformly corrected and recorded based on the system time of the event recording and early warning processing device 4, which is 10:01:05.

[0059] When the identification signal is received, the received identification signal, the start time of the identification signal, the duration, and the vehicle status data are recorded, and the vehicle control pedal image, the vehicle interior image, the vehicle front image, the sound, and the vehicle status data are stored in a time-based association.

[0060] The system determines whether the received identification signal, its start time, duration, and vehicle status data match the parameters of a preset driving event database. This database includes preset condition parameters such as accidental accelerator pedal press and speeding events, as well as preset warning action parameters. Based on these parameters, the system determines whether the received identification signal matches the parameters and whether the start time and duration of the identification signal reach parameter thresholds.

[0061] If so, the preset warning action corresponding to the preset driving event database will be matched, and the warning prompt will be fed back to the driver with sound and image.

[0062] If not, the received identification signal and the start time and duration of the identification signal are tracked to determine whether they exceed the preset safety parameter range of the preset driving event database. If they exceed the preset safety parameter range, the driver is prompted with sound and image that the current driving scenario cannot be identified and to pay attention to safe driving. The system also confirms whether to update the identification signal data received in the current scenario to the preset driving event database parameter record. The recorded parameters can be used for subsequent warning identification.

[0063] When recognition signal six, recognition signal five, and recognition signal two are simultaneously detected, and the acquired vehicle status data matches the preset driving event database parameters, the preset driving event database parameters are invoked to issue an audio and visual warning to the driver. For example, if recognition signal six indicates the car is accelerating, recognition signal five indicates "brake," and recognition signal two indicates the accelerator pedal is pressed, the preset driving event database parameters are invoked to issue an audio and visual warning to the driver that "you have pressed the wrong accelerator pedal, please press the brake instead."

[0064] The identification signal 1, identification signal 2, identification signal 3, identification signal 4, and identification signal 5 are digital identification codes or letter identification codes. The preset driving event database determines whether the parameters match the digital identification code or the letter identification code. The identification signal 6 is vehicle status data. Using identification codes as identification signals enables unified and rapid management of each identification module without occupying the device's processor memory and other resources for identification and calculation, thereby accelerating the efficiency of identification, early warning, and linkage.
