Description
Technical field
The present invention relates to image acquisition technologies, more specifically to a kind of video recording screening arrangement.
Background technique
With the continuous progress of science and technology with development, the video recording equipment that individual carries increasingly is minimized, hidden to other people
Take on the sly etc. illegally making video recording makes one to be difficult to discover, and this behavior illegally recorded a video not only causes serious shadow to party
It rings, or even will cause serious classified information leakage.
The some video recording interference methods used now have: one is for wireless transmission function wireless camera,
The wireless transmission of this camera is interfered, to interfere the work of total camera, but for the nothing of self-contained storage hard disk
Line camera, although video recording is stored, so still getting video recording not over wireless transmission locally；It is a kind of
It is using physical method using smoking device, prevents the target illegally recorded a video from protecting needs, this method is easy to be examined
Feel, and is inconvenient to use in the biggish region of flow of the people, and smoking device volume is larger, is not easy to personal carrying；There are also one kind
It is to interfere household WIFI camera using the interference to WIFI, still fall within the form of air interference in itself.
Video recording interference method or device as described above all have limitation, not square on the one hand because volume great Yi is noticeable
Just implement；On the other hand video recording can only be interfered to transmit, the storage of video recording and itself itself can not be interfered.Therefore, city at present
There is not yet itself the photosensitive effective video recording countermeasure set that can be recorded a video with direct interference on face.
Summary of the invention
Deficiency in view of the above technology, the present invention provide a kind of video recording screening arrangement, which can be imaged with direct interference
Itself, normal Video data can not all be obtained by being whether locally stored or transmitting wirelessly, and the device volume is small, power consumption
It is low.
The present invention is achieved through the following technical solutions:
A kind of video recording screening arrangement, including pedestal and the sweep mechanism being mounted on the base, which is characterized in that above the pedestal
Master board and direction motor are installed, disk is installed above the direction motor, drive laser is installed above the disk
The sweep mechanism of arraymotion；The sweep mechanism includes pitching motor, scanning frame and the laser being mounted in scanning frame
Array, the pitching motor scan frame by being slidably connected；Cover is also equipped on the pedestal.
Preferably, the master board, direction motor, disk, sweep mechanism are installed in cover；The side
To the main shaft of motor by bearing clutch disk, the disk is described to sweep by connecting rod cam slide mechanism connection scanning frame
It retouches frame and pitching motor is connected by screw rod slide block mechanism.

Preferably, the main control chip uses STM32F103 chip.
Preferably, the laser array is using near-infrared laser transmitting probe as array element.
Preferably, the cover uses the light transmission dark glass cover in semicircle shape.
Compared with prior art, beneficial effects of the present invention:
1. the present invention is based on optical principle, with the near-infrared light waves of invisible wave band, in the object week for needing to prevent video recording
It encloses and generates stronger scanning light beam face set, and be scanned in particular directions according to set mode, when strong optical scanning is arrived
When the camera illegally recorded a video, since the optical lens of camera front end has wide-angle characteristic, light beam collection is further enhanced
It closes, so that light intensity is much larger than on the saturation threshold of imager chip, and CMOS or CCD sense in the imaging circuit of common video recording equipment
In optical chip spectral characteristic, when light intensity reaches photoelectricity saturation threshold or more, the output distortion of sensitive chip will cause, thus
Imaging front just interferes video recording equipment work, and the image for obtaining video recording is almost complete white video recording, realizes finder screen
The purpose covered；
2. the interference illegally recorded a video on specific direction may be implemented in the present invention, individual privacy information caused by illegally recording a video is prevented
Leakage；
3. the present invention can shield the video recording equipment of nearly all model, itself can be imaged by direct interference, make local deposit
Storage and wireless transmission can not all obtain normal Video data；
4. video recording interference of the present invention also based on black light, has the characteristics of not noticeable, to facilitate arrangement；In addition, of the invention
Also has the characteristics that small in size, power consumption.

Specific embodiment
Below by embodiment, the present invention is described in further detail.
As shown in Figure 1, 2, a kind of video recording screening arrangement, including pedestal 1 and the sweep mechanism being mounted on pedestal 1, pedestal 1
Master board 7 and direction motor 4 are installed in top, are equipped with disk 3 above direction motor 4, the main shaft of direction motor 4 passes through bearing
Clutch disk 3, disk 3 are slidably connected sweep mechanism by connecting rod cam mechanism；Sweep mechanism includes pitching motor 5 and scan box
Frame 6, pitching motor 5 scan in frame 6 by screw rod slide block mechanism connection scanning frame 6 and are equipped with laser array 8.
Sweep mechanism mainly drives laser array 8 to move back and forth, and scanning light beam is formed, when 4 continuous rotation of direction motor
When, frame 6 is scanned under the action of connecting rod cam mechanism, is moved reciprocatingly around rotation center, and reciprocating motion sweeps laser array 8
The angle retouched is 75 degree of angles.
Laser array 8, as array element, forms the battle array of 100x5 using 770~880nm near-infrared laser transmitting probe
Column, pop one's head in spacing 5mm, and each mutual angle in central axes of popping one's head in successively increases, the laser that array projects in space from centre to two sides
