Embodiment 1

[0023] figure 1 It is an implementation flowchart of a vehicle video repair method provided by an embodiment of the present invention, and the details are as follows:

[0024] In step S101, obtain a read and write request for key information in the vehicle video;

[0025] In step S102, the type of data in the read and write request is detected;

[0026] Among them, the types include invariant data types and variable data types.

[0027] The data type of key information is divided into two parts: invariant data type and variable data type. In this way, the number of reads and writes of the unchanging data type will be greatly reduced, and the probability of data block damage will also be greatly reduced.

[0028] In step S103, when the type of the data is an invariant data type, store the data in an invariant data storage area;

[0029] Wherein, when the type of the data is an invariant data type, the invariant parameters are stored in the invariant data storage area, and the invariant p...

Embodiment 2

[0039] This embodiment describes the implementation process of dividing the invariable data storage area and the variable data storage area before step S103 of the on-vehicle video repair method. The details are as follows:

[0040] In the storage device, all data blocks are divided into a constant data storage area and a variable data storage area.

[0041] The storage device can be any existing storage device, such as a magnetic disk, random access memory, flash memory, read-only memory, programmable read-only memory, electrically erasable programmable memory, registers, etc.

[0042] To facilitate the description, take the disk as an example, divide the disk into blocks, and adjust the block size according to the size of the disk. That is, the block size of the disk can be calculated by obtaining the disk size. Then a fixed number of blocks are combined into a block group for management. At the same time, super block information, block group description information, and root dir...

Embodiment 3

[0045] figure 2 It is the implementation flow chart of repairing in-vehicle video provided by this embodiment, which is detailed as follows:

[0046] S201: When the in-vehicle video is damaged, call data in the invariant data storage area;

[0047] S202: Repair the vehicle-mounted video according to the data.

[0048] Among them, call the data in the invariable data storage area, reconstruct the key information, and repair the data block in the vehicle video through the key information.

[0049] Take repairing car video as an example, the details are as follows:

[0050] A very important information of car video is time information. Therefore, the data organization structure of vehicle video here is divided into three levels.

[0051] 1. The root directory is used to store all date information in this disk;

[0052] 2. Time index information, used to store all the video data information of the day, including: video channel number, inode node, data type, video start and end time, video s...

Abstract

The present invention is applicable to the technical field of on-board video restoration, and provides a method and device for on-board video restoration. The on-board video restoration method includes: obtaining a read and write request for key information in the on-board video; detecting the type of data in the read and write request ; When the type of the data is an invariable data type, store the data in an invariable data storage area; when the type of the data is a variable data type, store the data in a variable data storage in the area. The invention avoids repeated reading and writing when reading and writing key information, so that when the vehicle video is damaged, the stored key information can be used to repair the upper and lower related video frames, thereby not only reducing the difficulty of vehicle video repair, but also improving Success rate of in-vehicle video restoration.

Description

Technical field [0001] The invention belongs to the technical field of in-vehicle video, and particularly relates to a method and device for repairing an in-vehicle video. Background technique [0002] With the popularity of monitoring equipment, many vehicles are equipped with monitoring equipment. Through the monitoring equipment, the information during the driving of the vehicle is recorded to generate on-board video. When a traffic accident or traffic dispute occurs, the responsible party can be judged by viewing the on-board video. Therefore, the on-board video is an effective evidence to resolve the traffic accident or traffic dispute. [0003] However, in the existing in-vehicle video surveillance system, the in-vehicle video is easily damaged, and the repair of the damaged in-vehicle video is difficult and has a low success rate. The reason is that the existing vehicle-mounted video uses the FAT32 file system to manage disk data. FAT32 files repeatedly read and write the ...
