Abstract:
Disclosed are a method and a device for adjusting a virtual reality image. The method comprises: acquiring first three-dimensional coordinates and a first attitude orientation of a positioning component ( 101 ); converting the first three-dimensional coordinates into second three-dimensional coordinates, and converting the first attitude orientation into a second attitude orientation ( 102 ); converting the second three-dimensional coordinates into target three-dimensional coordinates in a virtual space, and converting the second attitude orientation into a target attitude orientation in the virtual space ( 103 ); determining a projection plane in the virtual space ( 104 ); perspectively projecting a virtual object in the virtual space onto an imaging area in the projection plane to generate a two-dimensional image ( 105 ); and displaying the two-dimensional image on a display screen of a display module ( 106 ). The method and device allow the projection plane to be determined on the basis of the position and attitude orientation of a virtual reality device in the reality space and the two-dimensional image to be produced, thereby adjusting the virtual reality image provided by the virtual reality device according to the changes in position and attitude orientation of the virtual reality device in the reality space.

Claim (Index 1):
A method for adjusting a virtual reality image, comprising:\n acquiring first three-dimensional coordinates and a first attitude orientation of a positioning component of a virtual reality device in a reality space coordinate system, wherein, the reality space coordinate system is a three-dimensional coordinate system established by taking a specified point in the reality space as an origin; converting the first three-dimensional coordinates into second three-dimensional coordinates according to a preset first transformation relation, and converting the first attitude orientation into a second attitude orientation, wherein the second three-dimensional coordinates are coordinates of a focal point of a display module of the virtual reality device in the reality space coordinate system, and the second attitude orientation is the attitude orientation of the display module in the reality space coordinate system; converting the second three-dimensional coordinates into target three-dimensional coordinates in a virtual space according to a preset second transformation relation, and converting the second attitude orientation into a target attitude orientation in the virtual space; taking a point indicated by the target three-dimensional coordinates in any specified coordinate system in the virtual space as a projection center, and determining a projection plane in the virtual space according to the target attitude orientation; perspectively projecting the virtual object in the virtual space onto an imaging area in the projection plane to generate a two-dimensional image; and displaying the two-dimensional image on a display screen of the display module.
