Abstract
The present invention discloses a method for searching a video recording quickly. The method includes the following steps of selecting a plurality of key points on a line, recording positioning information corresponding to the key points, and performing one-to-one correspondence on the key points and list nodes, wherein geographical positions of the key points are corresponding to different numbers respectively; blending the key points into a vehicle video recording, and establishing a one-to-one correspondence relationship between video frames in a storage address of the video recording and the list nodes; when accidents or faults occur, providing, by a driver or a passenger, a general accident site and vehicle driving direction information, converting the accident site and the vehicle driving direction information into specific key point positioning information according to the one-to-one correspondence relationship; and calculating corresponding key points by using a key point algorithm, and quickly looking up the video recording corresponding to the accident site from the video recordings. According to the method, the key points on the line are set and are blended in the video recording, thereby burying a clue for looking up a video recording of a later event, and facilitating searching of a lot of video recordings.
Description
Technical field
The invention belongs to technical field of video image processing, relate generally to a kind of video record method for fast searching.
Background technology
Video monitoring is the important component part of safety and protection system, directly perceived with it, accurately, abundant with information content in time and be widely used in many occasions.In recent years, along with computer, network and image procossing, the developing rapidly of transmission technology, Video Supervision Technique there has also been significant progress.In video monitoring system is applied, video search is a kind of necessary functions, i.e. searches satisfactory video file according to the search condition specified in whole video file set, and user can check required video file by the function of video search.
But, file memory method of the prior art file by date, is placed in different files by type, owing to DVR upper channel is many, kind of event is many, when recording a video for a long time, a lot of video file may be there is on hard disk, be easily caused lookup speed slow.Add existing video file searching method, when a large amount of different types of video files are scanned for by video monitoring system, search speed is slow, and search step is complicated, takies multi-system resource simultaneously, affect other function of system, live video video recording can not be transferred timely, it is impossible to meet current high definition, in a large number for event reduction and investigation and evidence collection, the requirement of complex search video file, wastes substantial amounts of human and material resources.In addition, due also in video monitoring system, user more concerned be the video file of associated external event, the most various warning video files, to segment search the most further, increase search complexity further, it is less useful for user quick, accurately, search easily positions satisfactory video file, and want the manual video to correlating event time point to carry out location playback, accuracy rate is low, and it is difficult to operation, the most existing video searching method can not meet current high definition, in a large number, the requirement of complex search video file, the video record searching method that such a is new is extremely the most urgent.
Summary of the invention
In order to solve above-mentioned technical problem, the present invention provide a kind of can timely and effective, convenient, accurate, the video record file retrieving spot, incident time period, for event reduction and investigate and collect evidence provide video record method for fast searching the most easily.
The technical scheme is that
A kind of video record method for fast searching, comprises the following steps:
Several geographical position are selected on the line according to user's request, detection data according to vehicle-mounted acceleration transducer, obtain orientation and direction that vehicle runs, the vehicle uplink and downlink in diverse geographic location and same geographical position correspondence respectively is become the key point of difference numbering, record location information corresponding to key point and location information is numbered, key point, location information are stored with tabular form respectively, key point and list node carry out one_to_one corresponding, and list node and location information carry out one_to_one corresponding；
In vehicle traveling process on the line, when vehicle carries out video record, key point being mixed in recording a video into automobile video frequency, the frame of video in the storage address of video record sets up one-to-one relationship with list node；
When accident or fault occur, driver or passenger propose the site of an accident substantially and vehicle traffic direction information, according to one-to-one relationship, the site of an accident and vehicle traffic direction information are changed into specific key point location information；
Specific key point location information after conversion, utilize key point algorithm, calculate the key point of correspondence, according to the one-to-one relationship of key point with list node, and the one-to-one relationship of list node and video record, video record is quickly searched the video record that the site of an accident is corresponding.
As preferably, described key point algorithm comprises the following steps:
(1) spacing of specific key point location information and each location information is calculated successively；
(2) if being smaller than a certain set point, then it is assumed that the location information that specific key point positions information corresponding with key point is same interval；
(3) find out the list node that in step (2), key point is corresponding, find out, according to the storage address of video record corresponding to list node, the video record that the site of an accident is corresponding.
As preferably, described geographical position is place corresponding as interval using a certain regular length on the locality on circuit or circuit.
As preferably, described location information includes the longitude of key point, latitude and azimuth.
As preferably, location information corresponding to described key point is by GPS described point machine or vehicle-mounted GPS equipment collection.
The invention has the beneficial effects as follows:
The present invention arranges and is mixed by circuit key point among video record, changed by place gps coordinate, search clue is buried for the retrieval of late events video record, so facilitate the search to high-volume video record, can be timely and effective, convenient, accurately, retrieve spot, the video record file of incident time period, it is the most convenient to provide for event reduction and investigation and evidence collection, also meet current high definition simultaneously, in a large number, the requirement of complex search video record file, save substantial amounts of manpower and materials, solve that present stage search is slow and the problem of complicated time length.
