Abstract
The invention discloses a method for managing space-time correlation multi-channel video, which belongs to the fields of content-based video management, video retrieval, video processing and the like. Aiming at multi-channel video data acquired by outdoor scene acquisition, entertainment, sports rebroadcasting, video monitoring and the like, on the premise of ensuring that each video stream or each video file can be independently used, a real-time interactive set space-time sequence is allowed during external planning or playing by adding space-time information corresponding to a video frame, the multi-channel video playing combination is controlled, organic combination and picture complementation of multi-path video are realized, and the method also can be used for compounding the existing video and specific content video and is an interactive allowing multi-channel video management method. The method comprises a video space-time information organizing mode, a multi-space-time correlation method and a space-time correlation-based video combination method.
Description
Technical field
The present invention belongs to fields such as content-based video management, video frequency searching, Video processing.Multi-channel video data at acquisitions such as outdoor scene collection, amusement, physical culture relay, video monitorings, guaranteeing under the prerequisite that each video flowing or video file can use separately, by adding the space time information of corresponding frame of video, permission empty sequence when real-time, interactive is set from outside planning or when playing, the control multi-channel video is play combination, realize the organic assembling of multi-channel video and the complementation of picture, also can be used for realizing the compound of existing video and certain content video, is a kind of mutual multi-channel video management method that allows.
Background technology
In image data collection, security monitoring etc. are used, usually shoot with video-corder as equipment by multichannel and work simultaneously, the video data of being gathered all exists overlapping and redundant on time and space, when needs are watched the video of particular moment special scenes, in order to obtain comprehensive information, have to watch successively each video or it is carried out layout is required content after the montage, when similar demand is arranged, all to repeat similar work, the time-consuming and flexibility requirement that is difficult to satisfy the demands of complex operation.When video data is managed, existing method mainly is that each video flowing, video file, tape, CD etc. are marked, also have being exactly that video is divided into a plurality of segments as drama by the correlation of content indicates and manages, the MPEG committee has proposed the Managed Solution of related content, but because the restriction of describing method, also the product that is not described in detail and manages by content frame can be used.The multi-channel video dispatching method that existing multi-angle is switched in physical culture is relayed can be used, mainly be to use, but be different from the said also multi-channel video management method based on space time correlation of off-line definition of real-time edition of supporting among the present invention for manual operations in real time such as directors.The present invention is by independently arriving the space time information of each frame in detail to every road videograph, consistency by consistency on the time point of outside and locus, permission freely switches in the video of a plurality of associations same time point or locus, both supported multi-channel video management, the interactive operation in the time of also can realizing watching video data based on space-time.
Summary of the invention
The present invention includes the organizational form, multi-space correlating method of video space time information and based on three aspects of video combined method of space time correlation, execution sequence as shown in Figure 1.
For supporting many video managements based on space time correlation, must write down the space time information of scene that every section video writes down, no matter adopt absolute fix or relative positioning, this space time information should be able to be unified in the well-determined space-time framework.When information available comprises locus, the shooting of time, the apparatus for making a video recording of video acquisition the scene of gathering with respect to apparatus for making a video recording towards etc., this recording of information can detailedly arrive record frame by frame, also can be at a group of pictures, for settling relatively-stationary apparatus for making a video recording, also can closely write down once and get final product, should comprise following content (only be signal, order and actual name be not as the qualification to summary of the invention):
1. zero-time/frame number, 2. duration/frame number, 3. spot for photography, the sensing when 4. taking, 5. far away/close shot, 6. other descriptive informations whether.
Wherein, 1. and function 2. be the position of scene on time shaft of determine taking, density and mode according to the space time information record can adopt fixed intervals, also can adopt random fashion, for fixedly shoot with video-corder look like equipment only the record start time promptly with enough; 3. be the explanation in place when gathering video, position that can apparatus for making a video recording is a measuring point, and the scene that also can be taken is a measuring point, can adopt mode such as gps coordinate to realize that to the every group of video that will manage, specific mode should be unified according to convenience degree; 4. indicate photographed scene and shoot with video-corder the relativeness of picture between the equipment, and 3. in conjunction with realizing shooting with video-corder mutually that equipment is gathered the description of route or being the video acquisition point distribution at center with the target that is taken; The variation of lens focus when 5. being used to distinguish video acquisition, people's subjective factor during the reflection shooting; Other to the greatest extent information can include in 6. and make additional remarks.
The present invention does not limit the recording mode of space time information, can adopt the mode of plug-in file or embedded data, determines specific embodiments by practical application.
Space time correlation is the watching in sequence of user expectation when playing.The method of space time correlation and video combination is as follows:
1. at first determine the datum mark of space time information, at the space time information of each video as one group of vector in the time-space domain, p=(t, n, x1, y1, z1, x2, y2, z2, s), the acquisition time point of t for writing down in certain space-time information wherein, this temporal and spatial sampling point of n mark be from which video, (x1, y1, z1) spot for photography, (x2 for writing down, y2, the sensing during z2) for shooting, s is far away/close shot sign;
According to current assigned address, direction and far and near scape watch point (t, xa, ya, za, xb, yb, zb, s0), search is pressed close to this most and is watched a little sampled point in temporal and spatial sampling set, this is individual process very fast;
3. after determining closest approach, need analyze, determine its video sequence number of representative separately, the sequence number that is designed into as one group, is finished preliminary association other sampled points in closest approach and the neighborhood thereof;
4. the time of considering is unidirectional passage, need do further screening to the video that enters preliminary relation integration, only can selecting during operation, forward advances the time, for guaranteeing the level and smooth of video, select one with current video the locus and towards on immediate point be standby point, determine its video sequence number, as preparing video;
5. next is watched a little according to the sequential search of 2-4, if next standby corresponding good and current alternate video sequence number of video sequence number is consistent, switches to the preparation video, otherwise continuation broadcast current video, and repetition 2-5 is operated to end.
Multi-channel video based on the scene relating of space time information as shown in Figure 2, the viewing effect of video combination rear video is as shown in Figure 3.
