Embodiment 1

[0051] The image source for displaying FPV information is the display screen of the smartphone.

[0052] This embodiment utilizes the principle of reflection to generate the FPV information virtual image 5, which is realized by the semi-reflective and semi-transparent layer 9 in the visual screen 6.

[0053] A piece of Fresnel lens 3 is arranged between the smart phone and the visual screen 6, and the position of the lens can be changed to adjust the virtual image distance.

[0054] The light valve in the visual screen 6 adopts an electrically controlled liquid crystal layer 8, and the light transmission characteristics are changed by electric signals.

[0055] The smart phone is connected with the information center, that is, the remote controller 13 wirelessly with WIFI. The built-in sensor of the mobile phone collects the head motion signal, which is transmitted to the remote controller 13 by WIFI. Finally, it is used to control the viewing direction of the onboard camera...

Abstract

The invention discloses a head-mounted display device with multiple flight point views. The head-mounted display device comprises a wearing unit and an FPV (First-person Point View) information display unit, an imaging lens and a visual screen mounted on the wearing unit, the visual screen comprises a semi-reflection semi-transmitting layer, the FPV information display unit obtains and displays the FPV information sent from an aircraft, light of a displayed image passes the imaging lens, is then reflected by the semi-reflection semi-transmitting layer, and is displayed in the visual field of a wearer in the form of a virtual image, and natural light, as TPV (Third-person Point View) information, generated by the aircraft penetrates the semi-reflection semi-transmitting layer of the visual screen, and is transmitted to the eyes to generate a real image. The head-mounted display device can provided multiple flight point views and display TPV and FPV information simultaneously, and further, an operator can select to display or shut down any point view information to switch the point views under the condition that the display device is not taken off.

Description

technical field [0001] The invention relates to a head-mounted display device used in conjunction with unmanned aerial vehicles and aircraft model flights, in particular to a head-mounted display device with multiple flight viewing angles. Background technique [0002] In the flight of unmanned aerial vehicles and model aircraft, the operator usually observes and manipulates the aircraft visually from the Third-person Point of View (TPV), so as to perform takeoff, landing and near-field flight. At a relatively long distance (or beyond the visual distance), the operator will obtain the video and sensor signals returned by the airborne camera through the First-person Point of View (FPV) video glasses (or the display screen of the ground station), so as to control The aircraft flies. This way of relying on video glasses (or ground station) to obtain information to control flight is FPV flight. During the actual flight, the operator must shift the line of sight and wear (remov...
