Abstract
The invention provides a privacy protection method for a high-altitude parabolic monitoring camera, and belongs to the technical field of electronic engineering. The method is realized based on a fixing device and a privacy protection sheet, wherein the privacy protection sheet is mainly a transparent lens, and partial area on the lens is in an opaque state; fixing device fix the privacy protection piece at the front end of surveillance camera head, the position of whole privacy protection piece and its and the camera distance between, make the opaque region on the privacy protection piece just shelter from owner's window position in the video image. The invention can protect the privacy of owners while detecting high-altitude falling bodies and monitoring high-altitude parabolic behaviors.
Description
Technical Field
The invention belongs to the technical field of electronic engineering, relates to a high-altitude parabolic monitoring technology, and particularly relates to a privacy protection method for a high-altitude parabolic monitoring camera.
Background
High altitude parabolas are a significant problem that has to be faced in the urbanization process. Because the high-altitude parabolic behavior has the characteristic of difficult evidence obtaining, the high-altitude parabolic behavior becomes a criminal behavior with lower cost and great harm. The traditional high-altitude parabolic evidence obtaining method is to monitor the building in real time through a camera. This approach is often subject to owner resistance as it can lead to owner privacy disclosure. Some monitoring systems employ a camera mounted at a look-up angle to circumvent this problem. However, the method can not completely avoid privacy disclosure, and can cause the distance between floors in the shot image to be shortened, so that the inter-floor discrimination is reduced, and the difficulty of identification and evidence obtaining is increased.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides a privacy protector for a high-altitude parabolic monitoring camera. According to the invention, the additional equipment with a part of opaque area is added in front of the camera, so that the monitoring image can clearly see the flight track of a falling object, and the window of an owner is not shot
In order to achieve the purpose, the invention adopts the technical scheme that:
a privacy protection method of a high-altitude parabolic monitoring camera is realized based on a fixing device and a privacy protection sheet, wherein the privacy protection sheet is mainly provided with a transparent lens, and partial area on the lens is in an opaque state; fixing device fix the privacy protection piece at the front end of surveillance camera head, adjust the position of privacy protection piece and its and the camera distance between, make the opaque region on the privacy protection piece just shelter from owner's window position in the video image.
The opaque area on the privacy protection sheet is determined by the following method:
step 1: the monitoring camera is fixed outside the building and aligned with the building, so that the monitoring camera can work normally, and the monitoring camera does not move in the using process.
Step 2: and acquiring image information of the building through the camera.
And step 3: and projecting the image information of the building onto the privacy protection sheet. The projection can be physical projection, and projection relation can also be obtained through mathematical calculation; its implementation modes include but are not limited to laser engraving, printing and transfer printing.
And 4, step 4: on the privacy securing sheet, all areas corresponding to the building windows in the projection are set as opaque areas. Means for rendering the opaque regions opaque include, but are not limited to, printing, ablation, pasting, painting, and pre-adding an opaque medium during the lens manufacturing process.
The invention has the following effects and benefits: the invention can protect the privacy of owners while detecting high-altitude falling bodies and monitoring high-altitude parabolic behaviors.

Detailed Description
The following detailed description of the embodiments of the invention refers to the accompanying drawings.
A privacy protection method of a high-altitude parabolic monitoring camera is realized based on a fixing device and a privacy protection sheet, wherein the privacy protection sheet is mainly provided with a transparent lens, and partial area on the lens is in an opaque state; the fixing device fixes the privacy protection sheet at the front end of the monitoring camera, and the opaque area on the privacy protection sheet just shields the position of a window of a proprietor in the video image. The camera privacy protection method is characterized in that an additional device with a part of opaque areas is added in front of a camera, so that the monitoring image can clearly see the flight track of a falling object and does not shoot an owner's window. The method comprises the following steps:
step 1: the monitoring camera is fixed outside the building and is aligned with the building, so that the monitoring camera is positioned at an angle capable of working normally. The angle is guaranteed not to be changed in the subsequent use process through a cement pouring mode.
Step 2: the camera collects image information of the building.
And step 3: the image information of the building is printed on a paper board which is large than the privacy protection sheet. The position of a user window on the paper board is hollowed.
And 4, step 4: the paper is covered on the completely transparent privacy protection sheet original sheet, and after the privacy protection sheet below the hollow part of the paper board is changed into an opaque area in a painting mode, the paper board is removed.
And 5: air-drying privacy protection sheet.
Step 6: fix the privacy protection piece at the front end of surveillance camera head through fixing device, adjust the position of privacy protection piece and its and camera distance between, make the opaque region on the privacy protection piece just shelter from the window position of owner in the video image.
And 7: the privacy protection sheet is fixed in a cement pouring mode, and the position and the angle cannot be changed in the subsequent use process.
And 8: the video information is opened to owners, property and public security organs, so that high-altitude parabolic evidence can be conveniently obtained, and the worry of the owners about privacy problems is eliminated.
The above-mentioned embodiments only express the embodiments of the present invention, but not should be understood as the limitation of the scope of the invention patent, it should be noted that, for those skilled in the art, many variations and modifications can be made without departing from the concept of the present invention, and these all fall into the protection scope of the present invention.
