201. first driving image information is acquired, and the first driving image information comprises a driver.
The first driving image information can be acquired by a vehicle-mounted terminal arranged in a vehicle, the vehicle-mounted terminal can be an image acquisition device with a shooting function, an acquisition object of the image acquisition device is a driver, and the image acquisition device can be a camera built in a driving recorder or a camera which is arranged at other positions and can acquire images of the driver. The camera can be a 3D camera or a 2D camera, the 3D camera can acquire depth information of an image, and the body posture and driving behavior of a driver can be detected more accurately in an image detection engine based on the image depth information; the 2D camera acquires image information, can detect in an image detection engine based on the 2D image information, and is low in hardware cost; in some possible implementations, the image capturing device may also be a camera of the user end, and at this time, the user end needs to be adjusted to an angle and a posture capable of capturing the image of the driver.

And judging whether the similarity between the extracted characteristic value of the driving behavior and the characteristic value of the dangerous driving behavior in the dangerous driving behavior database is greater than or equal to a preset threshold, if so, determining that the driving behavior is the dangerous driving behavior, and if not, determining that the driving behavior is not the dangerous driving behavior. The dangerous driving behavior database stores characteristic values of various dangerous driving behaviors, and the dangerous driving behavior database can be understood as an independent database or a storage area for storing the characteristic values of the dangerous driving behaviors in a large database. If yes, go to step 105, otherwise go to step 106.

Referring to fig. 3, fig. 3 is a schematic flowchart illustrating a specific process of step 202 in the embodiment of fig. 2, as shown in fig. 3, including the following steps:
301. and carrying out image segmentation on the first driving image information through an image segmentation algorithm to obtain a plurality of image segmentation areas.
The image segmentation may be one or a combination of methods such as threshold-based segmentation, edge-based segmentation, region-based segmentation, cluster analysis-based image segmentation, wavelet transform-based segmentation, mathematical morphology-based segmentation, and artificial neural network-based segmentation. In the embodiment of the present invention, threshold-based segmentation is preferred, and the image may be segmented by using a histogram, that is, the grayscale histogram of the image is divided into several classes by using one or several thresholds, and pixels in the image whose grayscale values are in the same class are considered to belong to the same feature. The image in the first driving image information is segmented into a plurality of image segmentation areas by an image segmentation algorithm, such as: hand and steering wheel area, foot and pedal area, head and seat area, face area, other areas, etc.
302. And detecting the driving behaviors of the image segmentation areas, and extracting the image segmentation areas containing the driving behaviors to obtain the second driving image information.
The plurality of image segmentation regions are the image segmentation regions obtained in step 301, the detection of the driving behavior of the image segmentation regions may be performed by comparing pixel thresholds of the image segmentation regions, and the pixel thresholds may be understood as pixel thresholds of the template, such as: the method comprises the steps of taking pixel values on templates of a hand and a steering wheel as pixel threshold values, respectively calculating the pixel value of each image segmentation region when detecting a plurality of image segmentation regions, comparing the pixel value with the pixel threshold values, and calculating the similarity between the pixel value of each image segmentation region and the pixel threshold value, if an image segmentation region with the similarity between the pixel value and the pixel threshold value being greater than 98% exists, determining that the image segmentation region comprises the hand and the steering wheel, and taking the image with the maximum similarity as a second driving image when the image segmentation regions exist in a plurality.
Therefore, the first driving image is subjected to image segmentation, the obtained second driving image comprises the driving behaviors, and when the second driving image is detected, other background images can be prevented from being detected, so that the detection calculated amount is reduced, and the detection speed of dangerous driving behaviors is improved.
The image segmentation may be performed on the in-vehicle terminal device, on the user terminal device, or in the server.
Referring to fig. 4, fig. 4 is a schematic flow chart of another warning method for dangerous driving behavior according to an embodiment of the present invention, as shown in fig. 4, including the following steps:
400. the current driving environment condition is acquired.
The driving environment conditions include urban driving environment, highway driving environment, daytime driving environment, night driving environment, provincial or national road driving environment, rural road driving environment, and the like.
The driving environment condition can be judged according to the image acquired by the image acquisition device, for example, when the acquired image contains residential buildings or more pedestrians, the driving environment can be considered as an urban driving environment; when the acquired image contains a speed limit sign of the highway or a service area sign, the highway driving environment can be considered to be adjusted; when the light for acquiring the image is good, the driving environment in the daytime can be considered; when the light of the acquired image is not good, the driving environment at night can be considered; when the acquired image contains a provincial road or national road mark, the image can be regarded as a provincial road or national road driving environment; when the acquired image includes the field and crops, the environment can be considered as a rural road driving environment.
The above-described vehicle driving modes include a fuel-saving mode, a sport mode, an off-road mode, a cruise mode, and the like. The above-described driving mode of the vehicle may be acquired from a control system of the vehicle.
401. And acquiring first driving image information acquired by the image acquisition equipment in a timing or real-time manner according to the current environmental driving condition or the vehicle driving mode.
In the step, the image acquisition device can acquire images of the driver at regular time or in real time, and then the image acquisition device transmits the acquired first driving image information to the user terminal device or the server at regular time or in real time.
The above-described timing acquisition or real-time acquisition may be determined according to the current environmental driving conditions.
For example, when the current driving environment condition is an urban driving environment, the first driving image information acquired by the image acquisition device can be acquired in real time because the urban pedestrian volume and the urban traffic volume are large.
When the current driving environment condition is an expressway driving environment, the driver needs to keep high attention all the time due to high vehicle speed on the expressway, and first driving image information acquired by the image acquisition equipment can be acquired in real time.
When the current driving environment condition is a daytime driving environment, the first driving image information acquired by the image acquisition device can be acquired in real time on a road section with high pedestrian flow and high traffic flow, and the first driving image information acquired by the image acquisition device can be acquired at regular time on a road section with low pedestrian flow and low traffic flow.
When the current driving environment condition is a night driving environment, the night driving condition is poor, the driver needs to keep high attention all the time, and the first driving image information acquired by the image acquisition equipment can be acquired in real time.
When the current driving environment condition is a provincial road or national road driving environment, the first driving image information acquired by the image acquisition equipment can be acquired in real time due to the fact that the traffic flow of the provincial road or national road driving environment is small.
When the current driving environment condition is a rural road driving environment, the first driving image information acquired by the image acquisition equipment can be acquired in real time due to the fact that traffic flow of the rural road driving environment is low and signal quality is low.
The above-described timing acquisition or real-time acquisition may be determined according to the current vehicle driving mode.
For example, when the vehicle is in the fuel-saving mode driving, the first driving image information acquired by the image acquisition device can be acquired at regular time because the vehicle speed is not high.
When the vehicle is in a motion mode, the first driving image information acquired by the image acquisition device can be acquired in real time due to the fact that the vehicle speed is high.
When the vehicle is in the off-road mode, the driver needs to keep high attention all the time due to the complex road condition, and the first driving image information acquired by the image acquisition equipment can be acquired in real time.
When the vehicle is in a cruising mode, the association degree between the vehicle and a driver is low due to low vehicle speed, and the first driving image information collected by the image collecting device can be obtained at regular time.
402. And preprocessing the first driving image information to obtain second driving image information, wherein the second driving image information comprises driving behaviors.
403. And performing characteristic detection on the driving behavior of the second driving image.
404. Judging whether dangerous driving behaviors are included or not; if yes, go to step 405, otherwise go to step 406.
405. And sending out early warning prompt of dangerous driving behaviors.
406. And sending out a prompt of normal driving or not sending out any prompt.
In the embodiment of the invention, the collected image information of the driver is detected in a timing or real-time manner, so that dangerous driving behaviors of the driver can be detected in time. In addition, the acquisition mode is determined according to the current environmental driving condition or the vehicle driving mode, the mode of the first image can be switched under different current environmental driving conditions or vehicle driving modes, and the configuration of resources is optimized under the condition that the timeliness of detection is guaranteed.
Referring to fig. 5, fig. 5 is a schematic flow chart of another warning method for dangerous driving behavior according to an embodiment of the present invention, where as shown in fig. 5, the second driving image information includes a face of a driver, and the dangerous driving behavior includes continuous driving, the method further includes the following steps:
501. and performing face detection on the second driving image at the time of T1 to obtain a first face detection result.
The face detection may be performed on the face in the second driving image, and the first face detection result is used to indicate the features of the face at time T1, that is, to indicate who the driver is at time T1. The first face detection result may be a face feature value extracted by an image detection engine.
502. And performing face detection on the second driving image at the time of T2 to obtain a second face detection result.
The second face detection result is used to indicate the face features at time T2, i.e. to indicate who the driver is at time T2. The second face detection result may be a face feature value extracted by an image detection engine.
503. And calculating the similarity of the first face detection result and the second face detection result.
The similarity calculation may be euclidean distance calculation, cosine calculation, pearson correlation coefficient calculation, or the like between the face feature value in the first face detection result and the face feature value in the second face detection result.
504. Judging whether the driver at the time T1 is the same as the driver at the time T2; if yes, go to step 505, otherwise go to step 506.
And judging whether the time of T1 is the same as the time of T2 according to the similarity obtained by calculation in the step 503. Specifically, a threshold may be preset, so that whether the similarity is greater than the threshold is determined by comparing the similarity with the threshold, and if the similarity is greater than or equal to the threshold, it is indicated that the drivers at time T1 and time T2 are the same, and are the same driver. If the time is less than the time threshold, it is indicated that the driver at the time T1 is not the same as the driver at the time T2, and the driver may be changed by stopping the vehicle halfway. The difference between the time T1 and the time T2 is equal to or greater than a predetermined time, which may be a continuous driving time specified by traffic regulations, for example, 4 hours, or may be set by the driver.
505. If the driving condition is the same, the early warning prompt of continuous driving is sent out.
The early warning prompt of the continuous driving can be a voice prompt, a vibration prompt, a music prompt and the like.
506. If the current state is different from the current state, the current state is kept and no early warning prompt is carried out.
In some possible embodiments, the first detection result and the second detection result may also be driver identity information after identifying the driver. The determination of whether the driver is the same at time T1 and time T2 may be based on driver identification information, which may be information such as name, identification number, age, and the like.
The driver can keep the current state without early warning prompt, so that the condition that the attention of the driver in normal driving is dispersed due to prompt information can be avoided.
Thus, by determining whether the driver at time T1 is the same as the driver at time T2, it can be more accurately determined whether the driver has been driving continuously for a long time.
Referring to fig. 6, fig. 6 is a schematic flowchart illustrating a specific process of step 203 in the embodiment of fig. 2, as shown in fig. 6, including the following steps:
601. and extracting the driving behavior characteristic value of the second driving image.
In the embodiment of the invention, the dangerous driving behaviors comprise illegal driving behaviors, wherein the illegal driving behaviors can be that a user holds a steering wheel with one hand, leaves the steering wheel with two hands, does not watch the front of a road, continuously shakes the body (drunk driving or poisonous driving), places feet on an accelerator and a brake pedal simultaneously, and drives with bare feet, high-heeled shoes, slippers and the like. The driving behavior may include the relationship between the hands and the steering wheel, the relationship between the head and the seat, the relationship between the feet and the pedals, the human face, and the like of the driver. The driving behavior feature value may be extracted by an image detection engine, and specifically, the feature may be extracted by a convolutional neural network in the image detection engine.
602. And calculating the similarity between the driving behavior characteristic value and a preset illegal driving behavior characteristic value.
The driving behavior feature value may be obtained in step 501, and the preset violating driving behavior feature value may be the violating driving behavior feature value stored in the dangerous driving behavior database, and the driving behavior feature value is subjected to traversal comparison with the violating driving behavior feature value in the dangerous driving behavior database, so as to obtain the similarity between the driving behavior feature value and each violating driving behavior feature value in the dangerous driving behavior database. The similarity calculation may be a euclidean distance calculation, a cosine calculation, a pearson correlation coefficient calculation, or the like, between the driving behavior feature value and each of the illegal driving behavior feature values in the dangerous driving behavior database.
603. And judging whether the illegal driving behaviors are included or not based on the similarity of the driving behavior characteristic value and a preset illegal driving behavior characteristic value.
The above determination may be to set a similarity threshold, and determine whether the driving behavior is included by determining a relationship between the similarity between the driving behavior characteristic value and a preset violating driving behavior characteristic value and the similarity threshold, for example: and extracting characteristic values of the hand and the steering wheel, comparing the characteristic values with characteristic values of the illegal driving behaviors that the hand holds the steering wheel with one hand and the two hands leave the steering wheel, and if the similarity between the characteristic values of the hand and the steering wheel and the characteristic values of the illegal driving behaviors that the hand holds the steering wheel with one hand or the two hands leave the steering wheel with two hands is greater than a threshold value, determining that the illegal driving behaviors are contained. And extracting characteristic values of a body (including a head) and a seat, comparing the characteristic values with characteristic values of illegal driving behaviors which are not watched on the front of the road or continuously shaken by the body, and if the similarity between the body (including the head) and the characteristic values of the illegal driving behaviors which are not watched on the front of the road or continuously shaken by the body is greater than a threshold value, determining that the illegal driving behaviors are included.
By comparing the driving behavior with the illegal driving behavior, whether the driver is dangerous driving or not can be quickly judged.
