Detection method and system of near-to-eye display optical system, platform and electronic equipment

Abstract

The invention discloses a detection method and system of a near-to-eye display optical system, a platform and electronic equipment. The detection method of the near-to-eye display optical system comprises the steps of adjusting the pose of a detection camera to a pose to be detected according to an image of a first virtual target plate which is obtained by the detection camera and displayed by the near-to-eye display optical system so as to enable the optical center of the detection camera to be located at the center position of an eye box of the near-to-eye display optical system, wherein the optical axis of the detection camera points to the view field center of the near-to-eye display optical system; adjusting the pose of the spectrograph to the pose to be detected according to the relative pose between the detection camera and the spectrograph; and detecting a photometric index of the near-to-eye display optical system through the spectrograph.

Description

technical field [0001] The invention relates to the technical field of near-eye display, in particular to a detection method of a near-eye display optical system, a system and a platform thereof, and electronic equipment. Background technique [0002] In recent years, near-eye display optical systems such as AR (Augmented Reality, Augmented Reality) glasses or VR (Virtual Reality, Virtual Reality) glasses, etc. have created rich visual experience for human beings. Since the photometric index is an important index to evaluate the display effect of the near-eye display optical system, it usually includes brightness, brightness uniformity, contrast, GAMMA curve, color coordinates, color temperature and spectral energy distribution, etc.; therefore, before putting into service, the near-eye The photometric indicators of the display optical system are tested to check the product quality. [0003] At present, the photometric indicators of traditional flat panel display devices ar...

Problems solved by technology

However, this technical solution requires additional design and calibration of complex optical paths, resulting in high measurement costs and large system errors

In addition, this technical solution will not be able to see the entire virtual picture due to the small field of view of the camera. It is necessary to adjust the camera position several times to obtain a complete virtual image through image stitching technology, and then find the corresponding detection position. It will not only increase the complexity and difficulty of detection, but also introduce new errors, resulting in relatively low detection accuracy of photometric indicators
