As shown in fig. 2, the meaning of the pitch angle and roll angle of the tachograph is given.
In order to effectively identify the automobile, the guideboard, the fence, the lane line, the obstacle and the like which are running right ahead of the vehicle, the position of the skyline in the picture taken by the driving recorder needs to meet certain conditions no matter which vehicle type, and optionally, the position of the skyline needs to be in the middle of the picture and the skyline needs to be parallel to the upper edge and the lower edge of the picture. On the basis, in the driving process of the vehicle, the picture shot by the automobile data recorder is used as an analysis basis, the pitching adjusting angle and/or the rolling adjusting angle of the automobile data recorder are determined according to the position of the skyline in the picture, the influence of the vehicle type cannot be caused, and the obtained automobile data recorder visual angle adjusting result is more accurate. And the adjustment process only needs the picture shot by the automobile data recorder, and the data on the vehicle bus does not need to be acquired, namely the attitude angle of the vehicle does not need to be calculated, so that the data processing process is simpler.
In some embodiments of the invention, the pitch adjustment angle is obtained by a method as shown in fig. 3:
s201, determining the target position of the skyline in the picture; the vehicle event data recorder can be input into a control module of the vehicle event data recorder after the vehicle event data recorder is installed, for example, the middle position of a picture is used as the target position of the vehicle event data recorder, or the vehicle event data recorder is used for testing, the actual environment of the road is shot in the testing process, and then the most appropriate target position is selected and stored in the control module in advance.
S202, if the position of the skyline in the picture is closer to the direction of the sky than the target position, the pitching adjusting angle is used for controlling the upward adjustment of the view angle of the automobile data recorder; referring to fig. 4, in a picture 300 taken by a tachograph, a skyline 303 is formed at the intersection between the sky 301 and the road surface 302, the road surface includes two edge lines, namely a first edge line 304 and a second edge 305, and the center of the road surface also includes a lane line 306.

And S203, if the position of the skyline in the picture is closer to the direction of the road surface than the target position, the pitching adjusting angle is used for controlling the downward adjustment of the visual angle of the automobile data recorder. Steps S202 and S203 are performed in parallel. Referring to fig. 4, in one picture, if the skyline is closer to the road surface, i.e. lower, the view angle of the car recorder is higher, and the pitch angle should be adjusted to lower the view angle.
Obviously, adjust the pitch angle of vehicle event data recorder through this scheme, only need obtain the picture that vehicle event data recorder shot can, need not confirm the attitude angle of vehicle, also be applicable to in any motorcycle type moreover.
In some embodiments of the present invention, the position of the skyline in the picture is obtained by extracting the skyline in the picture as follows: inputting the picture into a skyline recognition model, and obtaining the position of the skyline on the picture according to the output result of the skyline recognition model; the skyline recognition model is obtained by machine learning training using a plurality of sets of training data, each set of training data comprising: a sample picture including a skyline and a label identifying a location of the skyline in the sample picture.

In some embodiments of the invention, the roll adjustment angle may be obtained by a method as shown in fig. 5:
s401: and analyzing the road surface in the picture to obtain the position of at least one edge line of the road surface in the picture. As shown in fig. 4, the road surface edge may include a first edge line 304 and a second edge line 305.
S402: and determining the rolling adjusting angle of the automobile data recorder according to the angle between the skyline and the sideline.
If the rolling angle of the automobile data recorder does not need to be adjusted, namely the skyline cannot be inclined, the direction of the road surface boundary line is fixed, and the included angle between the skyline and the boundary line should be maintained at a certain angle theoretically. If the angle is changed, it indicates that the shooting angle of view of the automobile data recorder rolls at the moment, and the rolling angle needs to be adjusted, and the adjusted rolling angle is required to meet the requirement that the included angle between the skyline and the sideline is maintained at a proper angle, and the proper angle can be stored in a control module of the automobile data recorder in advance, for example, the automobile data recorder is installed and then runs on the road surface, and a proper angle range is determined after the picture shot by the automobile data recorder is analyzed.

And once the roll angle of the automobile data recorder changes, the included angle between the skyline and the edge lines on the two sides of the road surface is unbalanced, the roll angle of the automobile data recorder should be adjusted, and the unbalance degree is reduced.
In some embodiments of the invention, the position of the road surface edge line on the picture is obtained by: inputting the picture into a side line recognition model, and obtaining the position of the road side line on the picture according to the output result of the side line recognition model; the sideline recognition model is obtained by machine learning training by using a plurality of groups of training data, and each group of training data comprises: the pavement marking device comprises a sample picture of a pavement and a label for marking the position of a border line of the pavement in the sample picture.
The machine learning model is trained by adopting a large number of sample pictures in advance through an artificial intelligence method, so that the machine learning model can have the function of automatically extracting the edge line in the picture, and therefore, in the process of adjusting the visual angle of the driving recorder, the edge line can be automatically extracted to obtain the position of the edge line in the picture as long as the picture shot by the driving recorder is input into the trained model.
In some embodiments of the invention, the roll adjustment angle may be obtained by a method as shown in fig. 6:
s501: and analyzing the position of a horizontal reference line in the picture. As shown in fig. 4, for the picture taken by the car recorder, the position of the horizontal reference line 307 can be determined, for example, according to the road edge line, according to the building appearing in the picture, and the like.
S502: and determining the rolling adjusting angle of the automobile data recorder according to the included angle between the skyline and the horizontal reference line.
If the rolling angle of the automobile data recorder does not need to be adjusted, namely the skyline does not incline, and the direction of the horizontal reference line is fixed, the included angle between the skyline and the horizontal reference line should be maintained at a certain angle theoretically. If the angle is changed, it indicates that the shooting angle of view of the automobile data recorder rolls at the moment, the rolling angle needs to be adjusted, the adjusted rolling angle is required to meet the included angle between the skyline and the horizontal reference line and is maintained at a preset angle, and the preset angle can be stored in a control module of the automobile data recorder in advance, for example, the automobile data recorder is installed and then runs on the road surface, and a picture shot by the automobile data recorder is analyzed and then determined to be within an appropriate angle range.
