Drawings

Detailed Description
In order to more clearly illustrate the embodiments of the present invention, the following description will explain the embodiments of the present invention with reference to the accompanying drawings. It is obvious that the drawings in the following description are only some examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be derived from them without inventive effort.
Example (b): the invention provides a vehicle end event related driving recording method, which is specifically realized in the following way:
the driving recording images are shot and stored through a camera carried by the vehicle or a driving recorder carried by the vehicle. The driving record image at least comprises a front and rear image of the vehicle, and can comprise an in-vehicle monitoring image.
And after the shot driving recording images are obtained, continuously storing the driving recording images to a buffer storage area in real time.
Furthermore, after the driving record image is shot, the image is preprocessed, and then the preprocessed image is stored in the buffer storage area. In the embodiment, the preprocessing may specifically include image compression, extraction, and streaming sorting, thereby improving the storage efficiency and subsequent calculation efficiency of the image.
Meanwhile, judging whether a key event to be recorded occurs according to the vehicle state, the passenger state and the short-distance object state; the vehicle state is an evaluation index of the safety risk of the vehicle, the passenger state is an evaluation index of the safety risk or the abnormality of passengers in the vehicle, and the close object state is an evaluation index of the risk that an object possibly collides with the vehicle.
Specifically, the vehicle state includes in-vehicle temperature information and vehicle system information, and the judgment criterion is as follows: and when the temperature in the vehicle exceeds a preset specified temperature range or an abnormal error report is sent by a vehicle system, determining that a key event related to the vehicle state occurs.
The passenger state comprises the health state and the behavior state of passengers in the vehicle, and the judgment criterion is as follows: when the life health indication of a certain passenger in the vehicle is analyzed according to the monitoring in the vehicle, or the behavior is analyzed to be abnormal (such as fighting), and the like, the key event related to the state of the passenger is judged to occur. Furthermore, the vital health signs of the passengers can be acquired and analyzed by health monitoring equipment such as a smart watch worn or worn by the passengers, and the health monitoring equipment triggers the judgment of the key event after detecting the abnormality.
The close object state is specifically an object with collision hidden danger near the vehicle, and the judgment criterion is as follows: when the sensing sensor of the vehicle senses that an object exists around the vehicle, the object enters a specified range near the vehicle and has collision hidden danger, the key event related to the close object state is judged to occur. The perception sensor can be a visual camera, a millimeter wave radar, an ultrasonic radar, a laser radar and the like.
Further, in order to further improve the accuracy of the above-mentioned close object state judgment, the specified range is set to vary according to the kind of the close object. When the short-distance target is judged to be a person or a bicycle through the data of the perception sensor, the specified range is set to be a fixed distance near the vehicle. When the short-distance target is judged to be other vehicles or objects through the data of the perception sensor, the specified range is set as the collision time multiplied by the relative speed between the vehicle and the short-distance target. The arrangement can reduce the misjudgment and avoid the situation that the video generated by the misjudgment occupies too much storage space.
When the key event is judged to occur, selecting a preset time range before and after the occurrence time of the key event, and transferring the driving image in the time range to a key event storage area. The part of the driving recording images record video data before and after an accident, and have great value for determining responsibility of the traffic accident.
Besides the occurrence time of the key event, the video generally has no great value, so that the ordinary driving recording images can be stored in a buffer storage area in a continuous covering mode, and the old driving recording images are gradually covered according to the time sequence after the buffer storage area is full. Therefore, the timeliness of the valuable driving recording image is improved, data of the key event storage area can be preferentially called for inspection after an accident occurs, and the accident analysis efficiency is improved.
In addition, for the key events judged for different reasons, different time range spans can be set for the driving record images triggered by the key events respectively, so that the storage space is saved, and the complete driving record images are provided as much as possible. For example, for determining a key event triggered by an abnormal vital signs of passengers, since some acute diseases generally have a period of onset, in-car videos which are stored for five minutes before and after the key event occurs can be stored in a key event storage area. For vehicle collision, the front and back processes are generally short, and sufficient information can be provided only by transferring one minute of video.
And further. When a plurality of key events occur simultaneously and the unloading time ranges overlap, only the maximum value in each unloading time range corresponding to the plurality of key events is required to be used as the actual unloading time range.
The embodiment also provides a vehicle end event related driving recording system, which applies the method, and the system structural diagram and the interaction relationship among the system structural diagram are shown in fig. 1, and the system comprises an image preprocessing module, an event filtering module, an image processing module, an image caching module and a key event image storage module;
the image preprocessing module is used for acquiring and preprocessing the driving record images and sending the preprocessed driving record images to the image caching module and the event filtering module;
the event filtering module receives the driving record images, analyzes the vehicle state, the passenger state and the short-distance object state according to the driving record images, judges whether a key event occurs or not, and filters the time without the key event; and after receiving the filtering result, the image preprocessing module sends the time information corresponding to the key event to the image processing module.
The image processing module is used for sending the corresponding time range to the image cache module according to the time information corresponding to the key event, calling the driving record image in the specified time range from the image cache module, and transferring the driving record image to the key event image storage module.
It should be noted that the above-mentioned embodiments are merely illustrative of the preferred embodiments and principles of the present invention, and those skilled in the art will appreciate that there are variations in the specific embodiments based on the ideas provided by the present invention, and these variations should be considered as the scope of the present invention.
