Abstract

The invention discloses a testing method and device for near-to-eye display equipment and a storage medium. The method comprises the steps of adjusting the entrance pupil plane of an image capturing module to be aligned with the exit pupil plane of a near-to-eye display optical system after the entrance pupil plane of the image capturing module is located in the eye box region of the near-to-eye display equipment to form a detection light path, acquiring a picture with a complete test image as a test picture, acquiring a corresponding relation between the test picture and imaging parameters of the test image, acquiring pixel coordinate parameters of pixels meeting a limit value on an image boundary on the test picture based on a preset pixel brightness parameter limit value of the test picture, and calculating and outputting a measurement result of the field of view of the near-to-eye display equipment. According to the testing method provided by the invention, the test efficiency is improved by acquiring the complete test picture, detecting the view field boundary and calculating and outputting the view field degree. The testing device provided by the invention only needs least equipment and system settings, and the test platform is easy to build.

Description

technical field

[0001] The invention relates to the field of near-eye display optical systems, in particular to a test method and a test device for the field of view of an optical display screen for near-eye display. Background technique

[0002] A near-eye display device (NED, Near-Eye Display) refers to a display device that creates a virtual image within the field of view of one or both eyes. At present, this technology is widely used in virtual / augmented reality display (VR / AR) products, and its application development momentum is very rapid. Among them, the field of view (FOV, Field of View) is a very important performance index: the improvement of the field of view can better display the picture and directly affect people's visual experience; it can also provide a better immersive experience and increase the sense of reality .

[0003] Since the near-eye display device forms a virtual image with a larger field of view, the test method of the field of view test in the...
