Embodiment 1

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

[0024] In step S101, obtain the read and write request of the key information in the car video;

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

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

[0027] Divide the data type of key information into two parts: immutable data type and variable data type. In this way, the number of reads and writes of the invariant data type will be greatly reduced, thereby greatly reducing the probability of data block corruption.

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

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

Embodiment 2

[0039] This embodiment describes the implementation process of being divided into a constant data storage area and a variable data storage area before the step S103 of the vehicle-mounted video repair method, and the details are as follows:

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

[0041] The storage device may 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, and the like.

[0042] For ease of description, a disk is taken as an example, and the disk is divided into blocks, and the block size is adjusted 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 synthesized into a block group for management. At the same time, the super block information and...

Embodiment 3

[0045] figure 2 It is the implementation flowchart of repairing the vehicle video provided by the present embodiment, and is described in detail as follows:

[0046] S201, calling the data in the invariable data storage area when the on-board video is damaged;

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

[0048] Among them, the data in the unchanging data storage area is called, the key information is reconstructed, and the data blocks in the vehicle video are repaired through the key information.

[0049] Taking the repair of car video as an example, the details are as follows:

[0050] A very important piece of information in car video is time information. Therefore, the data organization structure of the car 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, which is used to store all video data information of the day, including: video channe...

Abstract

The invention belongs to the technical field of vehicle-mounted video restoration, and provides a restoration method and device for a vehicle-mounted video. The restoration method for the vehicle-mounted video comprises the steps that a read-write request of key information in the vehicle-mounted video is acquired; the type of data in the read-write request is detected; when the data are invariant data, the data are stored in an invariant data storage zone; when the data are variable data, the data are stored in a variable data storage zone. According to the method and device, because it is avoided that the key information is repeatedly written and read, upper and lower correlated video frames can be restored through the stored key information when the vehicle-mounted video is damaged, the difficulty of restoring the vehicle-mounted video is lowered, and the success rate of restoring the vehicle-mounted video 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. 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 is generated. When a traffic accident or traffic dispute occurs, the responsible party can be judged by viewing the on-board video, so the on-board video is effective evidence for resolving traffic accidents or traffic disputes. [0003] However, in the existing vehicle video monitoring system, the vehicle video is easily damaged, and the repair of the damaged vehicle video is difficult and has a low success rate. The reason is that the existing vehicle video adopts the FAT32 file system to manage the disk data. The FAT32 file repeatedly r...
