If there are multiple tracking cameras all can carry out track up to destination object, tracking control unit carries out track up according to preset strategy select target tracking camera and by described target following video camera to destination object.
Wherein, described preset strategy refers to: tracking control unit distributes the table of comparisons according to tracking camera free memory and timeslice, determine target following video camera and by described target following video camera, destination object is carried out to track up, wherein, the pre-configured tracking camera free memory of described tracking control unit and timeslice are distributed the table of comparisons.
Wherein, described video data information comprises: movable information; The behavioural information of moving target; The face information of moving target.
Wherein, described analysis result comprises: the direction of motion of moving target; The behavior of moving target; Face recognition result.
Wherein, the behavior of described moving target comprises: teacher is in the face of student's direction and show drawing board, page of data, books.
The present invention also provides a kind of on-line synchronous classroom intelligent tracking system, comprising: one or more tracking cameras, one or more image collection video camera, behavioural analysis processor, tracking control unit; Wherein, described tracking camera is connected with described tracking control unit; Described behavioural analysis processor is connected with described image collection video camera, described tracking control unit respectively;
Described image collection video camera, for collecting the video data information of moving target and the described video data information of collecting being sent to described behavioural analysis processor;
Described behavioural analysis processor, for the described video data information receiving is analyzed, obtains analysis result and described analysis result is sent to described tracking control unit;
Described tracking control unit, for according to the described analysis result obtaining, determines that corresponding tracking camera carries out track up to destination object.
The on-line synchronous classroom intelligent tracking system structure chart that Figure 1 shows that the embodiment of the present invention 1, comprising: tracking camera A, tracking camera B, tracking camera C, tracking camera D; Image collection video camera E, image collection video camera F; Behavioural analysis processor, tracking control unit.
Tracking camera A, tracking camera B, tracking camera C, tracking camera D are distributed in multiple positions in classroom, for example: on the wall of dais one side, on the wall on opposite, dais, on the wall of both sides, classroom, particular location can be determined as required flexibly.
Image collection video camera E, image collection video camera F can install in multiple positions in classroom, (comprising: movable information for the video data information of collecting moving target (comprising: teacher, student); The behavioural information of moving target; The face information of moving target) and the video data information of collecting is sent to behavioural analysis processor; In the present embodiment, adopt two image collection video cameras, when actual deployment, can dispose as required one or more.
Behavioural analysis processor is analyzed the video data information receiving, and obtains analysis result and analysis result is sent to tracking control unit; Wherein, analysis result comprises: the direction of motion of moving target; Face recognition result; Wherein, if the direction of motion is to move upward, represent that student stands up; If move downward, represent that student sits down; If be non-moving up and down, represent walking about of teacher or student, may be move ahead, may be also to retreat.If detect face, represent that moving target is in the face of image collection video camera; If do not detect face, represent moving target back to or side facing to image collection video camera.
As shown in Fig. 2 (Figure 2 shows that the on-line synchronous classroom intelligent tracking system structure chart of the embodiment of the present invention 2), when motion, the identification of faces direction:
1) when showing the video data information that behavioural analysis processor provides from image collection video camera F that moving target is to the face data that moving target is not provided A direction motion and the video data information that provides from image collection video camera E, can judge that this moving target is towards A direction and proal, now do not consider that moving target is that transverse movement is (if consider the transverse movement of moving target, image collection video camera E to face wall on install again an image collection video camera G or image collection video camera F to face wall on an image collection video camera H is installed again, image collection video camera G or H collect the face information of this moving target equally, so that behavioural analysis processor determines this moving target is towards which direction).
2) when drawing moving target the video data information that behavioural analysis processor provides from image collection video camera F to the motion of C direction and not detecting face data; The video data information providing from image collection video camera E, draw target to the motion of B direction and detect face data, can judge that this moving target is Backward Right.
Analysis result also comprises: the behavior of moving target, for example: teacher is in the face of student's direction and show the data such as drawing board, page of data, books, now, tracking control unit determines that corresponding tracking camera is to close-up shot of teacher, thus can from take picture see clearly teacher show data in information.
Tracking control unit, according to the described analysis result obtaining, determines that corresponding tracking camera carries out track up to destination object.
If only there is a tracking camera to carry out track up to destination object, tracking control unit determines that this tracking camera is target following video camera and by described target following video camera, destination object is carried out to track up.
If there are multiple tracking cameras all can carry out track up to destination object, tracking control unit carries out track up according to preset strategy select target tracking camera and by described target following video camera to destination object.
Wherein, preset strategy refers to:
Tracking control unit distributes the table of comparisons according to tracking camera free memory and timeslice, determines target following video camera and by described target following video camera, destination object is carried out to track up; Wherein, the pre-configured tracking camera free memory of described tracking control unit and timeslice are distributed the table of comparisons.
| Tracking camera free memory X (unit: G) | Timeslice is distributed | Tracking camera | Priority |
| 0＜X≤1 | 2 seconds | Tracking camera 1 | The 3rd priority |
| 1＜X≤2 | 6 seconds | Tracking camera 2,3 | The second priority |
| X＞2 | 10 seconds | Tracking camera 4 | The first priority |
Table 1: tracking camera free memory and timeslice are distributed the table of comparisons
Wherein, in table, the scope of tracking camera free memory X, timeslice distribution can be carried out the setting of numerical value according to actual needs, do not do any restriction at this.
As above described in table, first by the tracking camera 4 of the first priority, destination object is carried out to track up 10 seconds, if take completely in 10 seconds, finish; If also do not take completely in 10 seconds, by destination object being carried out to track up 6 seconds one of in the tracking camera 2 or 3 of the second priority, if take completely in 6 seconds, finish; If also do not take completely in 6 seconds, by the tracking camera 1 of the 3rd priority, destination object is taken 2 seconds.
