Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
In general, prior art is the broadcasting speed arranging monitor video according to the motion conditions of the object in monitor video picture when playback monitor video, when the speed of the object in video pictures is larger, the broadcasting speed of suitable reduction monitor video, when the speed of object is less, the broadcasting speed of suitable raising monitor video, to improve the effect of viewing monitor video.But, not all dynamic menu that during checking monitoring video, we pay close attention under normal conditions, we more pay close attention to certain region in video pictures under normal circumstances, and prior art all goes to consider from whole video pictures, can not emphasis be carried out check in selection portion split screen region from monitor video.The embodiment of the present invention just proposes a kind of method of broadcasting monitor video newly, by receiving the input information of user, the part picture area that can user selected to pay close attention in whole video pictures region is as target area, then the speed of the direct object according to occurring in target area controls the broadcasting speed of video, and the speed of other objects outside target area need not be considered, better can watch the relevant information of the object in target area, improve monitor video viewing effect, improve and check efficiency, make user's energy fast finding to the relevant information of the object paid close attention to.
Fig. 1 shows the schematic block diagram of the method for the broadcasting monitor video according to the embodiment of the present invention.Method shown in Fig. 1 can be performed by the player on computer or other-end equipment.The method of Fig. 1 comprises:
110, receive the first input information of user, this first input information is used for select target region from the video pictures of described monitor video.
Should be understood that before the first input information receiving user, first first can open monitor video by player, and demonstrate the video pictures of monitor video, so that next therefrom select the region paid close attention to according to the video pictures region of display.Above-mentioned reception user first input information mode have multiple, such as, user can by the associative operation button on player or mouse selection portion split screen region in video pictures region, with this, the first input information is input to player.Specifically, user can select a part as target area from whole video pictures region by the line tool in player, the region that this target area i.e. user pay close attention to, translucent blocking can be carried out, with the outstanding target area that will check for the video pictures outside target area.Such as, for monitoring the video obtained at traffic intersection, major trunk roads region in video pictures can be selected as target area when playing, alpha-mask is then carried out, so that check the passage situation of the vehicle on major trunk roads in the video pictures region such as pavement for major trunk roads both sides.
120, determine whether there is moving object in target area.
Such as, when checking that traffic intersection monitors the monitor video obtained, major trunk roads region in video pictures can be selected as target area, after determining target area, just can check or determine whether have vehicle or pedestrian to pass through in major trunk roads region, and need not consider in the video pictures outside major trunk roads, whether have vehicle or pedestrian to pass through.
If there is not moving object in 130 target areas, this monitor video of F.F..
In general, usually can comprise a large amount of tableauxs in monitor video, such as, take in the monitor video obtained morning at traffic intersection, because vehicle is fewer, in monitor video, usually can comprise a large amount of tableauxs.If when wanting when checking this monitor video to view in target area the video pictures comprising moving object fast, need the tableaux fast skipped in video, the mode of F.F. at this moment can be adopted to play this monitor video.The speed of F.F. can be arranged according to actual conditions, such as, can be that the first fast forward speed plays monitor video, when playing above-mentioned monitor video with the first fast forward speed when F.F., video pictures can not produce hopping sense, and can and have the video pictures of moving object to be connected nature.
The mode of above-mentioned fast-forward play monitor video can have multiple concrete way of realization.Such as, when determining that target area does not have moving object, the speed being greater than normal speed can be adopted to play monitor video, and wherein, normal speed is the speed corresponding with the acquisition rate of monitor video.Specifically, if the acquisition rate of video is 30 frames/second, so normal speed also can be 30 frames/second, when target area does not have moving object, the speed of 60 frames/second can be adopted to play this monitor video, and like this, the totalframes due to whole monitor video is certain, so at this moment, broadcasting speed is exactly original 2 times, that is can skip the video pictures not having moving object in target area with less time.Should be understood that the acquisition rate of monitor video can be 24 frames/second, 25 frames/second, 30 frames/second etc., can think with this monitor video of normal speed forward if broadcasting speed is consistent with acquisition rate when playing this monitor video.In addition, the normal speed of the broadcasting of monitor video also can be different with acquisition rate, such as, when the acquisition rate of monitor video is 30 frames/second, normal speed can be set as 25 frames/second.Can think that when the speed of monitor video actual play is greater than normal speed F.F. (fast) is play, can think that when the speed of monitor video actual play is less than normal speed slow-motion (at a slow speed) is play.
In addition, can also be from whole frame pictures of monitor video, extract some key frames play during fast-forward play monitor video.Such as, a monitor video has 3000 frames, normal playback speed is 30 frames/second, normal speed is so adopted to finish the time that this monitor video needs 100 seconds altogether, when fast-forward play, from 3000 frames, extract 1500 frames play, each second still plays 30 frames, so only needs the time of 50 seconds just can play this monitor video.Therefore, on the whole, when F.F., the frame number of broadcasting each second is equivalent to 60 original frames, and the broadcasting speed that is during F.F. is original twice.When F.F., be not that the key frame of extraction is more few better, if the key frame therefrom extracted when playing is very few, so video pictures there will be jump or incoherent phenomenon.Therefore, can also be therefrom extract 2000 frames to play when F.F., the frame number that each second plays changes 40 frames into, also be like this within the time of 50 seconds, finish this video, but because the frame number play increases to some extent than upper a kind of mode, therefore, the effect of broadcasting may be better.Therefore, when fast-forward play monitor video, the speed play not is be the bigger the better, the key frame extracted neither be more few better, ensure that the picture of monitor video does not produce jump when playing, and ensure there is no the tableaux of moving object and have the dynamic menu of fortune merit object to want transition nature.
If there is moving object in 140 target areas, according to the broadcasting speed of the speed determination monitor video of this moving object, play monitor video with this broadcasting speed.
Should be understood that above-mentioned moving object can be one also can be multiple, when moving object is one, can arranges the broadcasting speed of monitor video, and then play this monitor video according to this broadcasting speed with the movement velocity of this moving object.When above-mentioned moving object is multiple, can considers according to the movement velocity of multiple moving object the broadcasting speed that video is set, and then play this video according to this broadcasting speed.
The movement velocity of above-mentioned moving object can calculate in several ways, such as, can be defined the movement velocity of moving object by the frame number of movement in the same pixel compartments 1 inherent video pictures in second at the same position of calculating moving object, the movement velocity of moving object can adopt the unit of frame/second to represent.
In the embodiment of the present invention, according to the input Information Selection target area of user, the video pictures of the target area that energy quick position is paid close attention to user, and the broadcasting speed of monitor video is determined according to the speed of the object in target area, the broadcasting speed of monitor video and the speed of object can be made to match, improve the view result of monitor video.
Alternatively, as an embodiment, when comprising the different moving object of multiple speed in target area, can receive the second input information of user again, this second input information is used for selection portion partial objectives for object from multiple moving object; Finally the direct speed according to the target object in target area determines the broadcasting speed playing monitor video, and plays this monitor video with this broadcasting speed.
In the embodiment of the present invention, by selection portion componental movement object from multiple moving object as target object, directly the speed playing monitor video can be set according to the speed of target object, the broadcasting speed of video is more mated with the speed of target object, improve control precision and result of broadcast, make user can better check the relevant information of target object.
Specifically, when there is multiple moving object in target area, if the speed of these moving objects is also different, so in order to observe the relevant information of componental movement object wherein, can from target area, an object be selected to observe again.More targeted at checking monitoring video like this, better effect can be obtained.Above-mentioned second input information can be that user carrys out select target object by mouse click from the moving object target area, when the method playing this monitor video is performed by player, when player just can determine which moving object is target object after receiving this second input information, then the direct speed according to target object removes the broadcasting speed controlling monitor video.
Alternatively, as an embodiment, after have selected target object, can also receive the 3rd input information of user, the 3rd input information is used for carrying out convergent-divergent to the target object in video pictures.Specifically, when the method playing this monitor video is performed by player, user can pass through mouse select target object, then information is inputted by the mode of rolling pulley to player input the 3rd, player is after receiving the 3rd input information, reduce or the video pictures at amplification target object place, such as, can amplified video picture when target object is less in video pictures, video pictures can be reduced, so that check the relevant information of target object when target object is larger in video pictures.
Alternatively, as an embodiment, after have selected target object, the broadcasting speed of monitor video can be determined according to the movement velocity of target object.Specifically, when the speed of this target object is less than first threshold, determine to play above-mentioned monitor video with First Speed; When the speed of target object is greater than Second Threshold, determine to play above-mentioned monitor video with second speed; When the speed of target object is greater than first threshold and is less than Second Threshold, determine with the above-mentioned monitor video of normal speed forward, wherein, this normal speed is the broadcasting speed corresponding with the acquisition rate of video, first threshold is less than Second Threshold, First Speed is greater than normal speed, and second speed is less than normal speed.Should understand, here normal speed can consistent with the acquisition rate of video also can be inconsistent, as long as ensure the effect of monitor video when playing better, specifically, when the acquisition rate of monitor video is 30 frames/second, normal speed can be set to 30 frames/second, and normal speed also can be set to 25 frames/second.Will also be understood that, here target object can be one also can be multiple, when target object is multiple, it is that the speed of all objects represented in target object is all less than first threshold that the speed of target object is less than first threshold, and it is that the speed of all objects represented in target object is all greater than Second Threshold that the speed of target object is greater than Second Threshold.
Specifically, when the speed of target object is lower than first threshold, can think that the movement velocity of target object is lower, if at this moment still play this monitor video with normal broadcasting speed, significantly can feel that the movement velocity of moving object is too slow, viewing effect is not good.For this situation, viewing effect can be promoted by the broadcasting speed increasing video.In like manner, when the speed of target object is larger, if when still playing this video with normal broadcasting speed, significantly can feel the excessive velocities of target object, even there will be the phenomenon that picture jumps, be unfavorable for carrying out careful observation to the motion conditions of target object, at this moment can promote viewing effect by the broadcasting speed reducing video.Such as, the acquisition rate of a monitor video is 30 frames/second, so when the speed of target object is less than 30 frames/second, plays this monitor video with the broadcasting speed of 40 frames/second; When the speed of target object is greater than 40 frames/second, play this monitor video with the broadcasting speed of 25 frames/second; When the movement velocity of target object is greater than 30 frames/second and is less than 40 frames/second, play this monitor video with the normal speed of 30 frames/second.
The method of the broadcasting monitor video of composition graphs 1 pair of embodiment of the present invention is described above, is described in detail below in conjunction with the method for the concrete condition shown in Fig. 2-4 to the broadcasting monitor video of the embodiment of the present invention.
210, open video player, call in the monitor video that will play, enter the video pictures (as shown in Figure 2) playing monitor video.Should be understood that this video player can be arranged in computer, also can be arranged in the electronic equipment that other support playing function, the monitor video will first will play before playing monitor video imports in the playback equipments such as computer.
220, as shown in Figure 3, click " draw and the determine region " option on the window of video player upper left side, select target region, opens intelligent play mode, and as seen from Figure 3, the target area selected is the subregion of the road in left side in video pictures.When select target region, can be first utilize mouse to click " draw and determine region " option, and then rolling mouse select a part of region as target area in video pictures.
After selecting target area, just can adjust the broadcasting speed of monitor video according to whether having in target area moving object, when there is not moving object in target area, this video of F.F.; When there is moving object in target area, determine according to the movement velocity of moving object the broadcasting speed playing monitor video.
230, from the multiple objects target area, select an object as target object, control the broadcasting speed of video according to the movement velocity of target object.As shown in Figure 4, can an automobile below select target region as target object, specifically, can utilize mouse from the multiple objects target area, directly directly select an object as target object.
Specifically, when the speed of target object is less than first threshold, play monitor video with First Speed; When the speed of target object is greater than Second Threshold, play monitor video with second speed; When the speed of target object is greater than first threshold and is less than Second Threshold, with normal speed forward monitor video, wherein, first threshold is less than Second Threshold, and First Speed is greater than normal speed, and second speed is less than normal speed greatly.Should understand, here normal speed can consistent with the acquisition rate of video also can be inconsistent, as long as ensure the effect of video when playing better, specifically, when the acquisition rate of monitor video is 30 frames/second, normal speed can be set to 30 frames/second, and normal speed also can be set to 25 frames/second.That is the speed being greater than normal speed can be adopted monitor video is play when the speed of target object is less, the speed being less than normal speed can be adopted to play this monitor video when the speed of the object in target area is larger, be convenient to the relevant information of object observing object like this, realize good result of broadcast.
240, after selected target object, in order to the motion conditions of clearer object observing object, the broadcasting speed of monitor video not only can be adjusted according to the speed of target object, can also according to the motion conditions being carried out better object observing object by the target object in scaling video picture.As shown in Figure 4, here mouse can be moved to target object by image zooming, then corresponding zoom operations is carried out to target object, Fig. 4 and Fig. 3 contrast can significantly be found out, target object is only had in target area in Fig. 4, and in Fig. 3 in target area except target object below, also there is non-targeted object, and the video pictures that the video pictures that occupies of the target object in Fig. 4 occupies than the target object in Fig. 3 is large, therefore can the motion conditions of better object observing object by the video pictures after Fig. 4 convergent-divergent.
