Embodiment 1

[0037] Refer figure 1 A structural diagram of a virtual image distance measurement system provided by the embodiment of the present invention is shown. The virtual image is used to measure the virtual image of the display device 20, including the imaging device 101, reference object 102, and measuring device 103;

[0038] The imaging device 101 has a first imaging position S1 and a second imaging position S2, and the display device 20 is located on the optical axis of the imaging device 101; in the second imaging position S2, the reference object 102 is located on the optical axis of the imaging device 101;

[0039] When the imaging device 101 is confocated to the virtual object in the preset mode, the imaging device is confocated in the first imaging position S1, and the virtual object is clearly imaging in the imaging device 101;

[0040] The reference object 102 is configured to move along the optical axis in the second imaging position S2 and in the focus state of the imaging ...

Embodiment 2

[0057] Refer Figure 4 The step of determining a method of determining a virtual image distance provided by the embodiment of the present invention is shown. The virtual image distance measurement system is applied to an embodiment, the method comprising:

[0058] Step 301, when the photographing device 101 is in the first imaging position S1, the virtual object displayed by the display device 20 is focused in the preset mode, so that the virtual object is clearly imaging in the imaging device 101.

[0059] In this embodiment, the display device 20 displays a virtual object, and when the imaging device 101 is located on the optical axis of the photographing device 101, the imaging device 101 is focused on the virtual object in the preset mode. The object is clearly imaged in the photographing device 101.

[0060] Alternatively, the shooting parameters of the photographing device 101 are the longest focal length and the maximum aperture in the preset mode. That is, in the preset mod...

Abstract

The invention provides a virtual image image distance measuring system and a method for determining the virtual image image distance. The system includes a shooting device, a reference object and a measuring device; the shooting device is used to focus on the virtual object in a preset mode when it is in the first shooting position, so that the virtual object can be clearly imaged in the shooting device; the reference object is used to When the shooting device is in the second shooting position and in the focusing state, move along the optical axis until the image is clearly imaged in the shooting device; the measuring device is used to calibrate the distance between the reference object and the shooting device when the reference object is clearly imaged in the shooting device The distance between is the virtual image distance of the virtual object. The embodiment of the present invention makes the method for determining the image distance of a virtual image simple and easy to operate, can meet the detection and correction requirements of display devices such as virtual reality equipment and augmented reality equipment, and solves the problem of high equipment requirements for determining the image distance of a virtual image in the prior art.

Description

Technical field [0001] The present invention relates to the field of virtual technology, and more particularly to a method of determining a virtual image distance measurement system and a virtual image pitch. Background technique [0002] Virtual Reality, VR) and Enhancement Reality (AR) are like a virtual image, where the measurement of the virtual image is very important. Because the virtual image is directly affected by the effect of anti-distortion and spatial position depth, it is visually close to the consumer feel of the display device. If the virtual image is incorrect, it will directly affect the matching of the hardware and software parameters and the final effect of the display device. [0003] Currently, it is determined that the virtual image is mainly: 1. The imaging formula is obtained according to the imaging formula of the optical system. 2. Take a photo of the display device using a transmissive camera, and the spacing and virtual image distance are obtained by ...
