A virtual reality fog screen generating device

Abstract

The invention provides a virtual reality fog screen generating device which comprises a transduction cavity, a steam curtain cavity, an air curtain cavity and an intelligent control system which are arranged from inside to outside in a sleeving mode. An ultrasonic transduction chamber is arranged at the bottom in the transduction cavity, and a pressure and temperature adjusting chamber is arrangedabove the ultrasonic transduction chamber; a plurality of sets of transduction modules arranged side by side are arranged in the ultrasonic transduction chamber, steam fog ducts are arranged on the two sides outside the transduction cavity, and the bottoms of the steam fog ducts are converged, communicated and connected with a steam curtain nozzle set; air curtain ducts are arranged on the two sides outside the steam curtain cavity, the bottoms of the air curtain ducts are connected with air curtain nozzle sets, and the air curtain nozzle sets are arranged on the left side and the right sideof the steam curtain nozzle set. The intelligent control system comprises an embedded automatic control system and a convolution edge calculation system. The innovative cavity and culvert pipe are adopted to form an air curtain-steam curtain-air curtain structure, the ultrasonic transduction module is adopted to achieve efficient liquid-steam conversion, the holographic fog curtain which is stablein output, large in size and high in anti-interference capacity is achieved, and fog curtain output can be dynamically adjusted according to the complexity degree of image content.

Description

technical field [0001] The invention belongs to the field of projection technology, in particular to a virtual reality fog screen generating device. Background technique [0002] The current fog screen output device has a simple structure and no automatic control; the vertical size of the screen type output is small, the screen shape output is uneven, and the effective area for carrying images is very limited and rough; the lower part of the fog screen is scattered and difficult to form, and the visual effect is relatively poor , it is difficult to display a complete output image; it is easily disturbed by site temperature, wind speed, and wind direction; the output form generally adopts the form of pressure injection, which greatly pollutes the humidity of the site environment; The degree of complexity adjusts the reflectivity of the fog film, so that it cannot better present the clear details of complex images, and it is difficult to apply it to commercial holographic inte...
