Calibration method, calibration device and calibration system for near-eye display optical system

Abstract

A calibration method for a near-eye display optical system, a calibration device and a calibration system, wherein the calibration method includes: acquiring an image of a test image formed by an image source on a display unit; and obtaining the test image based on the image of the test image The position correspondence between the position of the source image in the image source and the imaging plane of the detection camera; based on this correspondence, the image of the test target collected by the detection camera is processed to obtain the test target The position of the source image corresponding to the target image in the image source is relative to the position information between the imaging planes of the detection camera; and processing the source image corresponding to the test target image with the virtual imaging model in the image The position information of the source relative to the imaging plane of the detection camera and the position information of the test target relative to the near-eye display optical system are used to obtain virtual image imaging parameters of the near-eye display optical system. In this way, automatic calibration is realized.

Description

technical field [0001] The invention relates to the field of near-eye display optical systems, in particular to a calibration method, a calibration device and a calibration system for a near-eye display optical system. Background technique [0002] In recent years, near-eye display optical devices such as Virtual Reality and Augmented Reality have created unique sensory experiences for humans. Before the related products are put into service, the performance parameters of many sensors on the device must be calibrated, as well as the relative positional relationship between the sensors to ensure that users have a good visual experience. [0003] Take the common augmented reality head-mounted display devices on the market as an example. Due to errors in the equipment manufacturing process, the performance parameters of each sensor of the head-mounted display device and the positional relationship between them are often inconsistent with the design values, resulting in many pr...

Problems solved by technology

However, these calibration methods often only calibrate a single parameter, and the calibration efficiency is low

Even, in some calibration methods, human assistance is required, regardless of the high cost, which is not conducive to the development of calibration in the direction of industrial automation
