Embodiment 1

[0023] figure 1 It is an implementation flowchart of the vehicle-mounted video file repair method provided by the embodiment of the present invention, and is described in detail as follows:

[0024] In step S101, obtain the cluster linked by the cluster number of the in-vehicle video file that cannot be copied;

[0025] Detect whether the event that cannot copy the vehicle video file has occurred, when an event that cannot be copied occurs, find the vehicle video file according to the event, and in the vehicle video file chain, obtain the cluster linked by the cluster number of the vehicle video file that cannot be copied.

[0026] In step S102, it is judged whether the cluster corresponds to a plurality of vehicle-mounted video files;

[0027] In the in-vehicle video file chain, the in-vehicle video files corresponding to the cluster are acquired, and when the number of corresponding in-vehicle video files is greater than one, it means that the cluster corresponds to multipl...

Embodiment 2

[0035] figure 2 It is an implementation process diagram of step S104 of the vehicle-mounted video file repair method provided by the embodiment of the present invention, and is described in detail as follows:

[0036] In step S201, according to the order of generation time, obtain the vehicle video file with the earliest generation time;

[0037] In step S202, the on-board video file with the earliest generation time is written into the cluster number.

[0038] Wherein, the cluster numbers of the plurality of vehicle video files are truncated, and the cluster numbers are written into the vehicle video files with the earliest generation time.

[0039] Release the cluster allocated to a plurality of vehicle video files, write the cluster number in the vehicle video file with the earliest generation time, and then redistribute the cluster number in the vehicle video file allocation table, for the earliest vehicle video files except the generation time Car video files are writt...

Embodiment 3

[0042] This embodiment mainly describes the implementation process of marking bad clusters, which is detailed as follows:

[0043] When the number of write failures of the cluster number exceeds a preset number of times, the cluster is marked as a bad cluster.

[0044] The user can pre-configure the preset number of times of storage, for example, 3 times, and when the number of failures to write the cluster number exceeds the preset number, the cluster will be deleted. After writing to this location again next time, skip it directly to prevent future write operations from being impossible after encountering a bad cluster in the file system.

[0045] In this embodiment, since bad clusters are marked, the situation that the in-vehicle video file cannot be written is avoided, and the validity and reliability of the in-vehicle video file are guaranteed.

Abstract

The invention is applicable to the technical field of vehicular videos and provides a repairing method and device of vehicular video files. The method includes: acquiring the clusters of the cluster number links of vehicular video files which cannot be copied; judging whether the clusters correspond to a plurality of vehicular video files or not; if so, acquiring the generating time of the vehicular video files; repairing the cluster number into the cluster number of the vehicular video file with the earliest generating time. By the method, the circumstance that vehicular video files are deleted when the vehicular video files cannot be copied, the vehicular video files are saved completely, and the usability of the vehicular video files is increased.

Description

technical field [0001] The invention belongs to the technical field of vehicle-mounted video, and in particular relates to a method and device for repairing a vehicle-mounted video file. Background technique [0002] With the popularization of monitoring equipment, many vehicles are equipped with monitoring equipment. Through the monitoring equipment, the information during the driving process of the vehicle is recorded and the vehicle video file is generated. When a traffic accident or traffic dispute occurs, the responsible party can be judged by viewing the car video file, so the car video file is effective evidence for solving the traffic accident or traffic dispute. [0003] However, the existing on-vehicle video file monitoring system will not repair the in-vehicle video file if it cannot be copied, but will only choose to delete it, resulting in incomplete preservation of the on-vehicle video file and low usability. The reason is that the existing vehicle-mounted vid...
