Problems solved by technology

[0003] At present, a kind of virtual reality glasses scheme is: including the upper screen and the right screen arranged at a certain angle to each other, and a transflective optical element is arranged between the upper screen and the right screen, and the light of the upper screen is reflected by the optical element Entering the left eye, the light from the right screen reaches the right eye through the transmission of the light splitting element, but because the semi-transparent and semi-reflective optical element has a certain thickness, when the incident light enters the optical element, the thickness of the optical element causes the same Multiple reflections and transmissions in optical element 30
As attached to the manual Image 6 As shown, when the incident light A1 emitted from the upper screen enters the optical element 30, the left eye should only see the reflected light C1, but because the optical element 30 has a certain thickness, it causes multiple reflections, causing the audience to see the reflection Light rays C2, C3; the incident light A1 emitted from the right screen enters the optical element 30. The right eye should only see the transmitted light B1, but it sees the transmitted light B2 due to multiple transmissions, and due to the reflected light C1, C2, C3 is reflected into the left eye successively; and the transmitted light rays B1 and B2 are transmitted into the right eye successively, so that both the left eye and the right eye will see image retention

[0019] see figure 2 , is a schematic structural diagram of an unmanned aerial vehicle system 200 provided by an embodiment of the present invention. The UAV system 200 includes a wearable display device 100 and a camera 80 for taking pictures from the first perspective of the UAV. The camera 80 is communicatively connected to the wearable display device 100 . The wearable device 100 includes: a first screen 10 , a second screen 20 , an optical element 30 , a first eyepiece 40 , a second eyepiece 50 , a first shade 60 and a second shade 70 . In this embodiment, the camera 80 is set on one side of the second screen 20, and is used to take pictures from the first angle of view of the unmanned aerial vehicle. The first screen 10 and the second screen 20 can be used to present the camera 80 shooting screen.

[0020] The first screen 10 and the second screen 20 are arranged at a predetermined angle to each other. In this embodiment, the first screen 10 and the second screen 20 a...

[0032] The second embodiment is basically the same as the first embodiment, except that the wearable device 300 of the second embodiment does not include the first shading member 60 and the second shading member 70, but includes a fixed frame 90, so The fixed frame 90 includes a first frame 91 and a second frame 92 facing each other in parallel and a third frame 93 vertically connecting the first frame 91 and the second frame 92, and the first screen 10 is arranged on the inner wall of the first frame 91, The second screen 20 is disposed on the inner wall 93 of the third frame, and the optical element 30 is disposed at the bisector of the angle formed by the first frame 91 and the third frame 93 and abuts against the second frame 92 . When the viewer wears the wearable device 300, a video image with a three-dimensional effect can be presented to the viewer.

Abstract

A wearable display device, comprising: a first screen, a second screen at a certain angle to the first screen, an optical element arranged between the first screen and the second screen, a first eyepiece and a second eyepiece, the The optical element can partially reflect and partially transmit the light emitted by the first screen or the second screen, the first eyepiece is used to watch the image of the first screen, and the second eyepiece is used to watch the image of the second screen, so The surface of the optical element is provided with an anti-reflection film, and the thickness of the anti-reflection film changes with the change of the incident angle formed between the light emitted by the first screen or the second screen and the optical element, so as to eliminate the optical element Ghosting caused by multiple reflections or transmissions of light.

Description

technical field [0001] The invention relates to a virtual reality technology, in particular to a wearable display device and an unmanned aerial vehicle system. Background technique [0002] With the development of science and technology, more and more glasses or helmet products are emerging in the fields of audio-visual playback, video games, and first-person drone flight. These products are roughly divided into virtual reality and augmented reality in terms of principle and user experience. Two categories. Virtual reality, the specific meaning is: the comprehensive use of computer graphics system and various reality and control interface devices to provide immersive technology in an interactive three-dimensional environment generated on the computer. Representative products include Oculus Rift and Sony Morpheus . Augmented reality is a new technology developed on the basis of virtual reality. It is a technology that increases users' perception of the real world through in...
