Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
A first embodiment of the present invention provides a method for data processing in a vehicle, as shown in fig. 1, and is applied to a vehicle event data recorder, where the vehicle event data recorder is an execution subject of the method for data processing in a vehicle according to the present invention. The method comprises the following steps:
step 101: monitoring an abnormal driving event for representing the abnormal driving state of the vehicle.
Specifically, the abnormal driving event represents that the driving state of the vehicle is abnormal. Further, in the present application, the abnormal driving event is an event in which an abnormality occurs in the driving state of the vehicle in the artificial driving behavior, and both the rapid deceleration and the rapid deceleration belong to the abnormal driving event. In this application, contain acceleration sensor among the vehicle event data recorder, can perceive the speed condition of vehicle through acceleration sensor to, vehicle event data recorder monitors through acceleration sensor to rapid acceleration and rapid deceleration. When there is a sudden acceleration or deceleration, an abnormal driving event is indicated.
After step 101 is completed, step 102 is performed: and when the abnormal driving event is monitored, acquiring event information corresponding to the abnormal driving event and a driving record image corresponding to the abnormal driving event.
Specifically, the event information includes various information among a driving state of the vehicle, a geographical position of the vehicle, and an event occurrence time. Accordingly, when the abnormal driving event is monitored, the event information corresponding to the abnormal driving event is acquired, and the method comprises the following steps: various information of a driving state of the vehicle when the abnormal driving event occurs, a geographical position of the vehicle when the abnormal driving event occurs, and a time when the abnormal driving event occurs is acquired. The automobile data recorder comprises an acceleration sensor and a GPS module, the driving state of the vehicle can be acquired through the acceleration sensor, and the geographical position of the vehicle can be acquired through the GPS module.
Meanwhile, when the abnormal driving event is monitored, the driving record image corresponding to the abnormal driving event can be obtained. Specifically, in the present application, the driving record image of the preset time period including the abnormal driving event is obtained, and since the rapid acceleration and the rapid deceleration are instantaneous, in the first embodiment, the preset time period may be a preset time period with the abnormal driving event as a starting time, for example, the time when the abnormal driving event occurs is 10:00, and the preset time period may be the last 1 minute from 10:00, that is, 10:00 to 10:01, so that the driving record image of the time period of 10:00 to 10:01 is obtained. In the second embodiment, the preset time period may be a preset time period with the abnormal driving event as the termination time, for example, the time of the abnormal driving event is 10:00, and the preset time period may be the first 1 minute of 10:00, that is, 09:59 to 10:00, so as to obtain the driving record image of the time period of 09:59 to 10: 00. In the third embodiment, the preset time period may be a preset time period with the abnormal driving event as an intermediate time, for example, the time of the abnormal driving event is 10:00:00, and the preset time period may be a time period including the abnormal driving event and the first 30 seconds and the last 30 seconds of the abnormal driving event, that is, 09:59:30 to 10:00:30, so as to obtain the driving record image of the time period of 09:59:30 to 10:00: 30.
Furthermore, when the driving recording image is obtained, a playing jump time point which takes the abnormal driving event occurrence time as the initial playing time of the image is established in the driving recorder image. For example, if the time when the abnormal driving event occurs is 10:00:00 and the preset time period corresponding to the driving recording image is 09:59:30-10:00:30, a play jumping time point is established in the driving recording image, and the play jumping time point is 10:00: 00.
According to the method and the device, the playing jump time point which takes the abnormal driving event occurrence time as the initial playing time of the image is established in the automobile data recorder image, so that the abnormal driving event occurrence time can be quickly jumped to when the automobile data recorder image is played, and a user can conveniently and quickly check the abnormal driving event.
After step 102 is completed, step 103 is performed: and establishing a corresponding relation between the event information and the driving record image, generating a video index file and storing the video index file.
Specifically, event information corresponding to an abnormal driving event and a driving record image corresponding to the abnormal driving event have a one-to-one correspondence relationship, and therefore, a correspondence relationship is established between the event information and the driving record image, and a recording index file is generated. For example, there is a first abnormal driving event corresponding to the first event information and a second abnormal driving event corresponding to the second event information. The first event information includes "hard acceleration," geographic location a, and event occurrence time 10: 00. The second event information includes "rapid deceleration", geographic position B, and event occurrence time 11: 00. The first abnormal driving event corresponds to the first driving recording image. The second abnormal driving event corresponds to the second driving record image. Then, a corresponding relationship between the first event information and the first driving recording image is established, and a corresponding relationship between the second event information and the second driving recording image is established, so as to generate a video index file, wherein the video index file comprises the corresponding relationship. And then, storing the video index file in the local driving recorder.
After step 103 is completed, step 104 is performed: and receiving a searching operation of a user based on the event information and/or the name of the driving record image, acquiring a target driving record image corresponding to the searching operation based on the video index file, and feeding the target driving record image back to the user.
Specifically, in the first embodiment, the user may perform a search operation on the driving record image based on the event information. In a second embodiment, the user may perform a search operation on the driving record image based on the name of the driving record image. In a third embodiment, the user can perform a search operation on the driving record image based on the event information and the name of the driving record image.
For the first embodiment, specifically, first, a search operation performed by a user based on event information is received, target event information is determined, then, a target driving record image corresponding to the target event information is searched based on the video index file, and finally, the target driving record image is fed back to the user. In a first embodiment, the user may perform the search based on a variety of information among the driving state of the vehicle, the geographic location of the vehicle, and the time of occurrence of the event. For example, the user performs a search operation with "rapid acceleration" and the geographic position a as the query conditions, so that the determined target event information includes "rapid acceleration" and the geographic position a, then searches the event information including both "rapid acceleration" and the geographic position a in the video index file, and takes the driving record image corresponding to the searched event information meeting the conditions as the target driving record image. The invention supports the simultaneous inquiry of various information in the event information and is convenient for the user to accurately position the driving record image.
Specifically, for the second embodiment, when the correspondence between the event information and the driving record images is established, the correspondence includes names of the driving record images, and thus, the recording index file includes names of the driving record images. Therefore, after receiving a search operation of the user based on the name of the driving record image, the name of the target image can be determined, then, based on the video index file, the target driving record image corresponding to the name of the target image is searched, and finally, the target driving record image is fed back to the user. For example, the user performs a search operation using "11-month 27-day video 1" as a search condition for the name, searches for a driving record image named "11-month 27-day video 1" in the video index file, and sets the searched driving record image as a target driving record image.
For the third embodiment, the third embodiment is a combination of the two embodiments, and those skilled in the art can implement the third embodiment by referring to the two embodiments, which are not described herein again.
Further, for the target driving recording image, the target driving recording image includes a play skip time point. Accordingly, in step 104, the target driving recording image including the play jumping time point is fed back to the user, so that the user jumps to the abnormal driving event occurrence time point based on the play jumping time point to start playing the target driving recording image when playing the target driving recording image. For example, if the playing jumping time point in the target driving recording image is 10:00:00, the user will directly jump to 10:00:00 to start playing when playing the target driving recording image.
In addition, the method of data processing in the vehicle of the invention further includes:
counting a counter for representing the occurrence frequency of the abnormal driving event when the abnormal driving event is monitored;
based on the counter, the number of times of occurrence of the abnormal driving event at the present time is determined.
Specifically, a counter for counting the number of occurrences of an abnormal driving event is provided in the drive recorder. The counter will count up once each time an abnormal driving event is sensed. The number of times of the abnormal driving event at the current moment can be determined through the counter. For example, if the count value of the counter is 10, it indicates that the number of times of the abnormal driving event occurred by the current time is 10.
