Advantage is, by the relative position that the memory address of memory goes recording of video to originate, and produce direction bitmap according to storage address information, can the basic running orbit of display-object object video effectively intuitively, when user only needs basic orientation information, this kind of method can save a large amount of time, improves user's work efficiency.When user needs more to further investigate destination object, the result of this kind of method is that more deep research provides foundation.Especially provide foundation for follow-up video is concentrated, can greatly reduce video concentrates operand, improves working, case handling efficiency (will conduct further description in Figure 18-20).In addition, adopt latitude, longitude information to determine memory address, simplifying calculating (such as: without the need to judging relative direction), saving memory space.
Figure 18 shows that another kind of structure Figure 112 ' of video frequency abstract retrieval server 112 according to an embodiment of the invention.The element that Figure 18 label is identical with Fig. 4 has similar function.In the embodiment of Figure 18, video frequency abstract retrieval server 112 comprises video and concentrates module 1802.Just because of this, the intelligence actual combat System's composition of video frequency abstract retrieval server 112 ' video concentration systems is comprised.In this video concentration systems, other portions and the structure except video frequency abstract retrieval server 112 ' all can adopt the dependency structure of Fig. 1 to Figure 17.
Video concentrates module 1802 selects to comprise described target video object in described multiple video video according to bitmap; The frame of video comprising described target video object of predetermined number is gathered each video of video of selecting, to produce multiple frame of video group from described; According to the described multiple frame of video group of described traffic direction splicing that described bitmap shows, to form concentrated video.As in the embodiment of Fig. 6 or Figure 14, video concentrates module 1802 can directly get rid of video monitoring devices 107, thus, saves the time that video is concentrated, improves the efficiency that video is concentrated, accelerate user's case handling efficiency further.
In one embodiment, video concentrates module 1802 and also comprises acquisition module 1804.N number of frame of video is gathered backward the first frame that acquisition module 1804 occurs from described target video object at each video, and gather forward M frame of video the last frame occurred at each video from described target video object, wherein, M and N is positive integer.In one embodiment, the duration that occurs in each video of the value of described M and N and described target video object is proportional.Advantage is, proportional by arranging the duration that M and N and target video object occur in each video, can reduce the collection of redundant image, save the time that video is concentrated, improve video thickening efficiency.
Figure 19 shows that the flow chart of video concentration method 1900 according to an embodiment of the invention.In step 1902, gather multiple videos in multiple geographical position.In step 1904, select target object video.In step 1906, described multiple video is stored in multiple memory address by geographical position according to described multiple video respectively.In step 1908, judge the traffic direction of described target video object according to described multiple memory address, and produce the bitmap that mark has described traffic direction.In step 1910, in described multiple video, select according to described bitmap the video comprising described target video object.In step 1912, gathered the frame of video comprising described target video object of predetermined number each video of video of selecting, to produce multiple frame of video group from described.In step 1914, according to the described multiple frame of video group of described traffic direction splicing that described bitmap shows, to form concentrated video.Wherein, step 1906 can adopt the method flow of Fig. 8 to Figure 10 or Figure 16 to Figure 17.
The flow chart of another video concentration method 1912 according to an embodiment of the invention shown in Figure 20.Figure 20 is further describing the step 1912 in Figure 19.In step 2002, the first frame occurred at each video from described target video object, gather N number of frame of video backward.In step 2004, gather forward M frame of video the last frame occurred at each video from described target video object, wherein, M and N is positive integer.In one embodiment, the duration that occurs in each video of the value of described M and N and described target video object is proportional.
Advantage is, by the relative position that the memory address of memory goes recording of video to originate, and produce direction bitmap according to storage address information, can the basic running orbit of display-object object video effectively intuitively, when user only needs basic orientation information, this kind of method can save a large amount of time, improves user's work efficiency.When user needs more to further investigate destination object, the result of this kind of method is that more deep research provides foundation.Especially provide foundation for follow-up video is concentrated, can greatly reduce video concentrates operand, improves working, case handling efficiency.In addition, proportional by arranging the duration that M and N and target video object occur in each video, the collection of redundant image can be reduced, save the time that video is concentrated, improve video thickening efficiency.
Embodiment and accompanying drawing are only the conventional embodiment of the present invention above.Obviously, various supplement, amendment and replacement can be had under the prerequisite not departing from the present invention's spirit that claims define and invention scope.It should be appreciated by those skilled in the art that the present invention can change in form, structure, layout, ratio, material, element, assembly and other side under the prerequisite not deviating from invention criterion according to concrete environment and job requirement in actual applications to some extent.Therefore, be only illustrative rather than definitive thereof in the embodiment of this disclosure, the scope of the present invention is defined by appended claim and legal equivalents thereof, and is not limited thereto front description.
