1. a kind of submarine pipeline ROV feels video post-process method, including:

  • Step 1, original video files are felt to ROV and establishes the corresponding data mapping tables in each direction, the data mapping tables packetThe information of point containing pipeline location, the one-to-one relationship of video file name and video time location information;

    Step 2, the file for searching the inverted order in video file, is converted to the file of positive sequence, and update the data mapping table;

    Step 2.1, all records in data mapping tables are read, according to the pipeline location point of the identical adjacent record of video file nameThe difference of information determines the direction of line walking, searches the file that records corresponding video file as inverted order opposite with line walking direction;

    Step 2.2, each frame for preserving inverted order file successively, is spliced into the video file of positive direction in reverse order;

    Step 2.3, mapping table is updated the data;

    Step 3, the data mapping tables of different directions are compared, missing record is searched, regarding for missing is made up with the video in other directionsFrequency file section;

    Establish unified mapping table;

    Step 3.1, all records in the data mapping tables of all directions are read, are compared, are present in when determining different eachDirection mapping table is recorded as missing record;

    Step 3.2, according to missing record and corresponding direction, described lack is found from the mapping table that other directions have the recordForget the video file section for recording other corresponding directions, the video file section in other directions found is copied into regarding for missingIn frequency file;

    Step 3.3, mapping table is updated the data, the data mapping tables in three directions are merged into a unified mapping table;

    Step 4, unified mapping table is read, search for and deletes Video Redundancy part, and updates mapping table;

    Step 4.1, all records in unified mapping table are read;

    Step 4.2, record is classified according to video file name;

    Step 4.3, to every a kind of video file, the numberical range of the corresponding pipeline location point information of video file is calculated;

    Step 4.4, judge the numberical range of the pipeline location point information of each classification with the presence or absence of intersection;

    Step 4.5, if there is intersection, then redundant video section is deleted;

    Step 4.6, unified mapping table is updated.
