Locomotive video data integrity automatic detection method

Abstract

The invention discloses a locomotive video data integrity automatic detection method comprising the following steps: (1) inputting multiple pieces of to-be-detected video data of a locomotive, acquiring video information corresponding to each piece of to-be-detected video data, and encapsulating each piece of to-be-detected video data in a default encapsulation format; and (2) acquiring and detecting each piece of to-be-detected video data after encapsulation, judging whether each data frame is complete according to the default encapsulation format during detection of each to-be-detected video data, determining whether the corresponding to-be-detected video data is continuous according to the judgment result of each data frame, and recording information of the data frames judged as incomplete data frames and video information corresponding to video data determined as discontinuous video data. The locomotive video data integrity automatic detection method of the invention is advantageous in that implementation and operation are simple and convenient, automatic detection of the integrity of batch video data can be realized, and the efficiency and precision of detection are high.

Description

technical field [0001] The invention relates to the technical field of locomotive video monitoring, in particular to an automatic detection method for the integrity of locomotive video data. Background technique [0002] At present, most of the locomotives are installed with on-board video surveillance systems, which generate a large amount of video data every day. After acquiring the video data, it is necessary to confirm and analyze the data. View the video data to understand the status of the locomotive during operation, and provide a basis for possible later failure and accident analysis. [0003] At present, the video data files generated by the locomotive video surveillance system mainly rely on the personnel of the information technology team of the segment to play them one by one to analyze and view the video, that is, the video data is mainly read in a single file and depends on the video analysis personnel to view the video data one by one. It needs to rely on man...

Problems solved by technology

[0003] At present, the video data files generated by the locomotive video surveillance system mainly rely on the Duanfang information team to play them one by one to analyze and view the video. It needs to rely on manual operation to directly play and view video files one by one. On the one hand, this method of manually inspecting locomotive video files is inefficient and cannot obtain high efficiency. When there are a large number of video files that need to be detected and analyzed, it has to A lot of manpower is invested in this work; on the other hand, the method of relying on manpower to view video data for analysis has problems such as inaccuracy and incompleteness, which are prone to missed detection and missing records, and for the analysis of a single data frame, It is usually impossible to see the problem of a single video data frame by relying on manual inspection. For example, if there is a frame loss or data error in the frame of the video file, it is often impossible to find it directly. Popular video players will automatically record the wrong frame or frame loss in the video Automatically skip to cover up the real situation of the video data file; in addition, after manual detection and analysis of the locomotive video, if it is necessary to go back to the target video, it is impossible to quickly locate the time point when a certain event or a certain state occurred
