Drawings
Other features, objects and advantages of the invention will become more apparent upon reading of the detailed description of non-limiting embodiments with reference to the following drawings:
FIG. 1 is a flow chart of the method of the present invention.
Detailed Description
The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the invention, but are not intended to limit the invention in any way. It should be noted that it would be obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit of the invention. All falling within the scope of the present invention.
According to the screen deformation detection method of the VR device, the screen deformation refers to any deformation of the screen of the image displayed to the wearer by the VR glasses, such as whole stretching, partial stretching, whole compression and partial reduction, which are illegally performed by an intruder. Since the visual field range that can be observed by the glasses of the wearer is certain (not referring to the field adjustable by the rotating head, but referring to the inherent visual field range in the case that the eyes are kept inconvenient), when the image is stretched or shrunk, the information of the image edge is correspondingly deviated from the visual field range or other information is added to the image edge. For example, a monolithic bridge in a real scene is narrow, and if the width of the monolithic bridge is increased due to distortion of the screen after the image is falsified, the wearer may easily step on the monolithic bridge with the increased width.
The picture deformation detection method of the VR equipment comprises the following steps:
a step of acquiring a real image: the VR glasses acquire real-time images of the real environment in front of the VR glasses through the camera to obtain real images; specifically, the VR glasses are provided with the cameras, and the cameras shoot real-time pictures, for example, front or rear cameras arranged on a smart phone are utilized when a WeChat video chat is conducted. The orientation of the camera that VR glasses have sets up with the dead ahead coaxial arrangement of VR glasses or parallel arrangement. The angle of view in front of the VR glasses depends on the viewing angle of the camera, and for example, if the lens of the camera is a wide-angle lens, the angle of view in front of the VR glasses is larger than that of a standard lens. Therefore, although the VR glasses wearer cannot directly observe the real environment with the glasses, the wearer can indirectly observe the real-time real environment in front because the VR glasses are the image of the real environment acquired by the real-time real camera, and the visual effect is similar to that of AR glasses.
A number image detection step: detecting the real image, and detecting whether a set number of laser spots can be detected in the real image within a set time period; if yes, the real image is considered to be not deformed and tampered; if not, prompting the wearer that the real image is deformed and tampered or the possibility of deformation and tampering exists;
the laser facula is formed by irradiating an emergent beam of a laser transmitter serving as a physical energy transmitter to a real environment; the physical energy emitter is arranged on the VR glasses; in particular, the light spot of one or more physical energy emitters falls at the edge of the real image. Once the real image is illegally stretched, the laser spots at the edge of the real image are out of the visual field, so that the number of the spots in the real image is found to be different from the set number.
The set number is set by the wearer.
A distributed image detection step: detecting the real image, and detecting whether laser spots in a set distribution relation can be detected in the real image within a set time period; if so, the real image is considered not to be tampered; if not, prompting the wearer that the real image is deformed and tampered or the possibility of deformation and tampering exists;
wherein, set for the distribution relation by VR glasses person of wearing through following mode and set for: the mechanical structure for determining the emission angle of the physical energy emitter is manually adjusted by a VR glasses wearer and is not controlled by the control software; and/or, a plurality of physical energy emitter mounting positions are arranged on the VR glasses, and one or more physical energy emitters are detachably mounted on the mounting positions. Particularly, when the VR glasses are disconnected, the VR glasses acquire the current distribution relation of the laser spots as the set distribution relation.
The set number is set by the wearer in the following way: mounting positions of a plurality of physical energy emitters are arranged on the VR glasses, and one or more physical energy emitters are detachably mounted on the mounting positions; the installation of the physical energy emitters on the installation positions causes the change of the resistance values on the circuits in the VR glasses, so that the installation number of the corresponding physical energy emitters is obtained according to the resistance values, and the installation number is used as the set number. In particular, the current limiting resistor is connected to the circuit, and when the physical energy emitter is connected to the circuit, the physical energy emitter is connected to the parallel resistor of the current limiting resistor, so that the resistance value of the circuit is changed.
The time period is set by the wearer;
the time period comprises a camouflage time window and an actually measured time window;
the disguised time windows and the measured time windows appear alternately in the time period, the time lengths between different disguised time windows are different, the time lengths between different measured time windows are different,
the physical energy emitter only emits energy in the measured time window and does not emit energy in the camouflage time window;
if the laser spots with the set number and the set distribution relation are detected in the actually measured time window and the laser spots are not detected in the disguised time window, the real image is considered to be not tampered; otherwise, the wearer is prompted that the overlay image is tampered or that there is a possibility of tampering.
An image output step: and outputting the real image to display equipment of VR glasses for display. In particular, the detection of the number and the distribution relation of the laser spots can be observed and detected by a wearer, and the laser spots can also be identified by software from an image displayed by VR glasses through the image.
The mechanical structure for determining the emission angle of the physical energy emitter is manually adjusted by a VR glasses wearer and is not controlled by the control software; and/or, a plurality of physical energy emitter mounting positions are arranged on the VR glasses, and one or more physical energy emitters are detachably mounted on the mounting positions. Specifically, since the structure for determining the emission angle of the physical energy emitter is a mechanical structure (for example, a mount of a laser emitter with adjustable left and right pitching angles), and is not controlled by software, it is blocked in information transmission that an intruder knows the emission angle of the energy emitter by reading software code information or data information, for example, the intruder cannot know at which position on a desktop a laser beam emitted by the laser emitter serving as the physical energy emitter forms a spot. Similarly, the installation positions of the plurality of physical energy emitters are arranged on the VR glasses, the installation positions of the physical energy emitters can be changed by a VR glasses wearer, and the installation positions of the physical energy emitters can also be changed, so that the intruder cannot know the position of the laser beam emitted by the laser emitter serving as the physical energy emitter to form the light spot. Furthermore, the mechanical structure and the installation position can be manually adjusted by a wearer, so that the emission direction of the energy emitter can be considered to be random for an intruder, and the intruder cannot restore and display the laser spot correctly after stretching or compressing the picture.
If necessary, the method also comprises a notification step: and informing the designated contact person that the VR glasses have been invaded illegally according to the instruction of the wearer.
The picture deformation detection method of the VR device provided by the invention is an embodiment of a picture deformation detection system of the VR device, and a person skilled in the art can realize the picture deformation detection system of the VR device by executing the step flow of the picture deformation detection method of the VR device.
According to the screen deformation detection system of the VR device, the screen deformation refers to any deformation of the screen of the image displayed to the wearer by the VR glasses, such as whole stretching, partial stretching, whole compression and partial reduction, which are illegally performed by an intruder. Since the visual field range that can be observed by the glasses of the wearer is certain (not referring to the field adjustable by the rotating head, but referring to the inherent visual field range in the case that the eyes are kept inconvenient), when the image is stretched or shrunk, the information of the image edge is correspondingly deviated from the visual field range or other information is added to the image edge. For example, a monolithic bridge in a real scene is narrow, and if the width of the monolithic bridge is increased due to distortion of the screen after the image is falsified, the wearer may easily step on the monolithic bridge with the increased width.
The picture deformation detection system of the VR equipment comprises:
a real image acquisition module: the VR glasses acquire real-time images of the real environment in front of the VR glasses through the camera to obtain real images; specifically, the VR glasses are provided with the cameras, and the cameras shoot real-time pictures, for example, front or rear cameras arranged on a smart phone are utilized when a WeChat video chat is conducted. The orientation of the camera that VR glasses have sets up with the dead ahead coaxial arrangement of VR glasses or parallel arrangement. The angle of view in front of the VR glasses depends on the viewing angle of the camera, and for example, if the lens of the camera is a wide-angle lens, the angle of view in front of the VR glasses is larger than that of a standard lens. Therefore, although the VR glasses wearer cannot directly observe the real environment with glasses, the VR glasses can indirectly observe the real environment in front of the wearer due to the fact that the image of the real environment is acquired by the real-time real camera, the wearer can indirectly observe the real environment in real time, the visual effect is similar to that of the AR glasses, but the virtual object is not superposed in the real scene, two virtual scene images, namely the real image and the laser sensing real image, acquired from the real scene are superposed, and the visual observation effect of the real image is identical or basically identical to that of the real scene.
