Abstract

The invention discloses a method and a device for determining positions of pixels on a VR display screen in a camera image, comprising: acquiring an image obtained by a camera capturing a pattern displayed on the VR display screen through a VR lens, wherein the pattern is formed by the VR display screen lighting the pixels at equal interval; determining the first position information of each bright pixel in the image and the second position information on the VR display, and establishing a correspondence between the first position information and the second position information; determining the third position information of each dark pixel point in the image in the area surrounded by each four closely adjacent bright pixel points; selecting any three bright pixel points based on each area,and determining first position information and second position information respectively corresponding to the three bright pixels by using the correspondence; and determining fourth position information of the dark pixels in the VR display screen according to the third position information of the dark pixels, and the first position information and the second position information corresponding to each of the three bright pixels.

Description

technical field [0001] The invention relates to the technical field of VR equipment testing, and more particularly, to a method for determining the position of a pixel point on a VR display screen in camera imaging, and a device for determining the position of a pixel point on a VR display screen in camera imaging. Background technique [0002] For the test of the lens in the VR (Virtual Reality, virtual reality) device, in order to better reflect the product status, it is necessary to establish a corresponding relationship between the image of the VR display screen shot by the camera through the lens in the VR device and the VR display screen. [0003] There is a large error in the correspondence between the camera imaging and the VR display screen established by using the existing technical solution. For example, the error of the camera imaging coordinate system corresponding to the VR display screen coordinate system is more than 5 pixels (pixel points). [0004] Therefo...
