Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
The embodiment of the invention provides a driving recording method, which is applied to a driving recorder with a plurality of cameras, and as shown in fig. 1, the method comprises the following steps:
step 101: acquiring a driving video obtained by a plurality of cameras of a driving recorder corresponding to shooting; specifically, in the running process of the vehicle, the driving videos obtained by shooting the plurality of cameras of the driving recorder are obtained.
Step 102: and synthesizing the driving videos into a three-dimensional driving video based on the timestamps of the driving videos.
In particular, the plurality of cameras may be integrated into a terminal device, which may be disposed at an upper portion of a roof of the vehicle, for recording a driving picture in a plurality of directions of the vehicle. The plurality of cameras may be disposed in a dispersed manner, and may be disposed in, for example, the front of the vehicle or the rear of the vehicle, or on both sides of the vehicle, for recording from a plurality of directions.
In practical application, the camera can swing up and down, left and right according to the command, so as to change the shooting angle of the camera, and the camera can shoot according to the specified shooting angle. In addition, the camera can adjust the focal length automatically based on the command so as to shoot according to the specified shooting focal length.
In practical application, the running speed of the vehicle can be acquired, when the running speed of the vehicle is not zero, the camera is controlled to be started for shooting, and when the running speed of the vehicle is zero, the camera is closed so as to save power. In addition, in order to realize the full-time monitoring of the vehicle, the camera can be started at full time intervals, so that the 7 × 24-hour omnibearing real-time monitoring of the vehicle can be realized.
In this embodiment, the cameras are arranged at a plurality of positions of the vehicle, and shooting is performed from different directions of the vehicle, so that the problems of shooting blind areas and deformation of shot pictures caused by recording from a single direction by a single camera can be avoided. Meanwhile, the driving videos shot by the cameras are synthesized into the three-dimensional driving video, so that the driving condition of the vehicle can be comprehensively restored, the driving data of the vehicle can be comprehensively recorded, and an important basis is provided for the driving safety diagnosis of the vehicle.
Further, in an embodiment, the method of step 101 includes:
acquiring the running speed of a vehicle;
determining shooting focal lengths and shooting angles of the multiple cameras according to the running speed;
and obtaining the driving videos shot by the plurality of cameras correspondingly based on the shooting focal length and the shooting angle.
In practical applications, in different driving processes of a vehicle, situations may occur in which a long-range view and a short-range view need to be shot. For example, in a wider area with a faster driving speed, in order to ensure that a comprehensive vehicle situation is shot, that is, a proper shooting range is shot, a picture at a longer distance may need to be shot, while for an area with traffic jam, a smaller vehicle speed and a shorter vehicle distance, a picture at a shorter distance may need to be shot in order to reasonably record a driving environment. Namely, when the vehicle speed is high, shooting can be carried out with a large focal length to obtain a long-range video; when the vehicle speed is slow, shooting can be performed with a small focal length, and a close-range video is obtained. In addition, for the shooting of cooperation distant view and close-range view, still can be based on the shooting demand, adjust and shoot the angle. For example, when a long shot needs to be shot, the camera can be adjusted to a smaller angle, and shooting is performed in a direction close to the original shooting angle, namely close to the horizontal direction; when a close shot needs to be shot, the camera can be adjusted to a large angle, namely, the camera is adjusted downwards, and shooting is carried out in a way of overlooking.
Further, in an embodiment, the step of determining the shooting focal lengths and the shooting angles of the plurality of cameras according to the driving speed includes:
judging whether the running speed is greater than a first threshold value or not, if not, setting the shooting focal lengths and the shooting angles corresponding to the multiple cameras as a first shooting focal length and a first shooting angle; if so, setting the shooting focal lengths and the shooting angles corresponding to the multiple cameras as second shooting focal lengths and second shooting angles;
wherein the first focal length is smaller than the second focal length, and the first angle is larger than the second angle.
Here, the first threshold, the first focal length, the first angle, the second focal length, and the second angle may be set on a case-by-case basis.
In practical application, the shooting focal length and the shooting angle of the camera can be determined according to the running speed, and the shooting focal length and the shooting angle of the camera can be adjusted directly based on the shooting picture of the camera.
Specifically, in an embodiment, the acquiring driving videos obtained by a plurality of cameras of the driving recorder corresponding to shooting includes:
acquiring a driving picture obtained by each camera in the plurality of cameras corresponding to shooting; the driving picture is a video picture in an initial driving video shot by the camera at an initial shooting focal length and an initial shooting angle.
Identifying the driving pictures obtained by shooting each camera, and determining the shooting focal length and the shooting angle corresponding to each camera; specifically, a driving picture obtained by each camera corresponding to shooting is identified by using an identification model so as to determine the shooting focal length and the shooting angle of each camera; when the driving picture shot by a certain camera identified by the identification model is a vehicle head scene, the shooting focal length of the camera can be set to be a first focal length so as to clearly shoot a close-range scene; when the driving picture shot by a certain camera identified by the identification model is the vehicle tail scene, the shooting focal length of the camera can be set to be the second focal length so as to clearly shoot the distant scene.
Shooting is carried out by utilizing the shooting focal length and the shooting angle corresponding to each camera, and the driving videos obtained by the plurality of cameras corresponding to shooting are obtained.
In practical application, the cameras are arranged at different positions, so that different cameras may have different shooting requirements for shooting. For example, a camera at the head of a vehicle may need to take a close-up view to capture the number of preceding vehicle tags, while a camera at the tail of a vehicle may need to take a far-out view to capture the number of rear vehicles and the distance between the rear vehicle and the vehicle. Therefore, based on different shooting requirements, the shooting focal length and the shooting angle of each camera are determined by using the initial shooting picture of each camera, so that the shooting requirements can be better met, and the driving road condition of the vehicle can be more flexibly recorded.
In practical application, in order to avoid repeatedly adjusting the shooting focal length and the shooting angle of the camera and reduce the calculation amount of the processor, the shooting focal length and the shooting angle of the camera can be determined by adjusting the focal length and the shooting angle of the camera once every a period of time. Specifically, a fixed time interval may be set, and the determination of the shooting focal length and the shooting angle of the camera may be performed once at every fixed interval set at intervals. In addition, the adjustment interval of the photographing focal length and the photographing angle may also be determined based on the speed of the vehicle. In the driving process of the vehicle, the vehicle can adjust the vehicle speed in different degrees based on different road conditions, and the adjustment intervals of the shooting focal distance and the shooting angle are determined based on the change of the vehicle speed, so that the actual driving condition of the vehicle can be more closely met.
Further, in an embodiment, the step of obtaining a plurality of driving videos obtained by a plurality of cameras of the driving recorder corresponding to shooting further includes:
acquiring the running speed of the vehicle once every preset time interval;
judging whether the difference between the running speed of the vehicle at the current time and the running speed of the vehicle at the previous time is greater than a preset threshold value or not; if so, executing the step of identifying the driving picture obtained by each camera corresponding to shooting, and determining the shooting focal length and the shooting angle corresponding to each camera; if not, the step is executed, and the running speed of the vehicle is acquired once every preset time interval.
In this embodiment, when the difference between the running speed of the vehicle at the next time and the running speed of the vehicle at the previous time is greater than a preset threshold, identifying a running picture obtained by shooting each camera at the current time, and determining a shooting focal length and a shooting angle corresponding to each camera; when the running speed of the vehicle is changed from slow to fast, the traffic flow is reduced, no obstacle exists in front of the vehicle, and shooting can be carried out by adopting the second focal length.
In practical application, when the road conditions are greatly changed, the running speed of the vehicle is greatly changed, so that the shooting focal length and the shooting angle are adjusted based on the change of the vehicle speed, and the shooting picture of the camera can be closer to the actual driving road conditions.
Further, in an embodiment, the step of synthesizing the driving videos into three-dimensional driving videos based on the timestamps includes:
determining the running speed of a vehicle, and the shooting focal length and the shooting angle of each camera in the plurality of cameras;
based on the driving speed, the shooting focal length and the shooting angle of each camera, converting the driving pictures obtained by each camera corresponding to shooting to obtain standard and uniform driving pictures;
carrying out three-dimensional image synthesis on the driving pictures with the same time in the standard unified driving pictures to obtain a three-dimensional synthesized image;
and performing video synthesis on the three-dimensional synthetic image based on the timestamp to obtain a three-dimensional driving video.
In practical application, due to different driving speeds, different shooting focal lengths and different shooting angles, the images possibly shot cannot be synthesized, or the synthesized images are abnormal and strange, so that the synthesized images can be used for subsequent use, the images shot by each camera can be converted based on the driving speeds, the shooting focal lengths and the shooting angles, and the driving images are converted into standard unified driving images and then synthesized by the standard unified driving images.
Specifically, in an embodiment, the step of converting the driving picture obtained by capturing by each camera based on the driving speed, the capturing focal length and the capturing angle of each camera to obtain a driving picture with a unified standard includes:
obtaining a speed conversion offset for converting the driving picture by the driving speed based on the driving speed;
based on the shooting focal length, obtaining a focal length conversion offset for converting the driving picture by the shooting focal length;
obtaining an angle conversion deflection for converting the driving picture by the shooting angle based on the shooting angle;
and converting the driving picture based on the speed conversion offset, the focal length conversion offset and the angle conversion offset to obtain a standard and uniform driving picture.
Here, the driving speed, the photographing focal length, and the photographing angle may be determined separately, and for the conversion offset of the driving picture conversion, the conversion of the driving picture is implemented using the determined conversion offset.
Here, the driving speed, the shooting focal length, and the shooting angle, and the conversion offset of the driving picture conversion can be determined based on the existing picture processing technology, and are not described in detail here. In addition, the synthesis process based on the conversion offset can also be implemented by using the prior art, and is not described herein again.

The scheme provided by the invention can reduce the recording blind area in the driving recording process, avoid the recorded driving picture deformation and ensure the integrity and the definition of the driving recording picture.
