During electric power deficiency, MICRO USB interfaces 220 can be used to connect charging equipment or connection external power source.
The RJ45 interfaces 230, for the image information that is obtained the camera device with wired connection mode and described
Image evidence information transfer corresponding to doubtful cheating is to cloud server；The WIFI antennas 240, for wirelessly to connect
Connect the image evidence information transfer corresponding to the image information and the doubtful cheating that mode obtains the camera device
To cloud server；
The cloud server is used to receive image information and the doubtful cheating institute that the camera device obtains
Corresponding image evidence information.
The usage scenario of the video capture device for being used to invigilate of the present invention is described in detail below.As Fig. 1-4 institute
Show, video capture device 1 is placed on examination scene first, then start the power supply of base 320, open video capture device 1.
Then, controller 40 can control the movement of roller 321 so as to drive video capture device 1 to find optimum photographing position.Controller
40 further according to examination scene spatial information, the area and height at scene of such as taking an examination, the middle bar 312 of adjustable telescopic rod 310 and interior
Bar 311 is stretched, and finds optimal shooting height.Then, according to the arrangement at the live examinee seat of taking an examination, the control of controller 40 the
The central area that one camera 120 and second camera 130 are shot is gathered in the most region of examinee, and shooting comprehensively as far as possible
Examination scene, do not stay monitoring dead angle.If shoot less than place, can by controller 40 control roller 321 do not timing
It is live that mobile and dynamic shoots examination.
Now, the image information that camera device 10 is shot is sent to high in the clouds clothes by way of wireless connection or wired connection
Business device or other cloud devices, the shooting picture of the first camera 120 and second camera 130 can be subjected to panoramic mosaic exhibition
Show.When receiving module 401 receives the image information that the camera device 10 is shot, sending module 402 can be by described image
Information is sent to computing module, and then computing module 403 can analyze image information, judge whether doubtful cheating, when
It is determined that when doubtful cheating be present, memory module 404 can store doubtful cheating information, and computing module 403 can calculate this
The corresponding examination field regions information of doubtful cheating.Then, controller 40 can be according to the examination field regions information
The zoom shot of zoom camera 130 is controlled, to obtain the image evidence information corresponding to the doubtful cheating.It is described
204 exportable alarm signal of prompting module, is reminded examinee, alerted or is disciplined as a warning, to prevent cheating.
The present invention can have found cheating in time and collect evidence, and improve invigilator's efficiency, reduce the workload of invigilator personnel, can
Auxiliary even substitutes invigilator personnel.
