Embodiment 1

[0042] Such as Figure 4 As shown, this embodiment provides a binocular head-mounted display device, which includes:

[0043] Two display units are respectively used to generate images for the left and right eyes of the user, and the images include a test image and a display image; wherein, each of the test images for the left and right eyes of the user has a test mark, and the two test Marks are gradually increased or decreased in spacing.

[0044] The image acquisition unit is configured to acquire images of both eyes of the user.

[0045] The interpupillary distance analysis unit is used to obtain the critical moment when the interpupillary distance of the user's eyes changes according to the images of the user's eyes when the user watches the test image, and determine the distance between the images viewed by the user's left eye and right eye according to the distance between the two test marks at the critical moment ; Among them, when the distance between the two test m...

Embodiment 2

[0048] This embodiment provides a binocular head-mounted display device, such as Figure 5 to Figure 10 As shown, it includes two display units 1, an image acquisition unit, and an interpupillary distance analysis unit.

[0049] Wherein, the two display units 1 are respectively used to generate images viewed by the user's left eye 8 and right eye 8, which can be conventional display devices such as liquid crystal display unit 1 (LCD) and organic electroluminescent display unit 1 (OLED). . Of course, in order to adapt to the head-mounted display device, the volume of the display unit 1 should be small and should have a relatively high resolution.

[0050] preferred, such as Figure 5 , Figure 8 As shown, the display unit 1 is arranged on the side of the binocular head-mounted display device (such as in the "spectacles"), so its display surface does not face the user's eyes 8, and the images it generates do not directly reach the user's eyes 8. At this time, the binocular h...

Embodiment 3

[0076] This embodiment provides a method for adjusting the image distance of a binocular head-mounted display device, including:

[0077] The two display units generate test images for the user's left eye and right eye respectively, and there is a test mark in each test image, and the distance between the two test marks increases or decreases gradually; image;

[0078] The interpupillary distance analysis unit obtains the critical moment when the interpupillary distance of the user's eyes changes according to the images of the user's eyes, and determines the distance between the images viewed by the user's left eye and right eye according to the distance between the two test marks at the critical moment; wherein, when the distance between the two test marks gradually When it increases, the interpupillary distance of the user's eyes gradually increases before the critical moment and remains stable from the critical moment. When the distance between the two test marks gradually ...

Abstract

The invention provides a binocular head-wearing display device and a method thereof for adjusting image spacing, which belongs to the technical field of head-wearing display. The binocular head-wearing display device can solve the problems of the prior art of complicated operation for image spacing adjustment and poor display effects and viewing experience. The binocular head-wearing display device comprises two display units, an image acquisition unit and an interpupillary distance analysis unit, wherein the two display units are respectively used for generating test images and display images for the left eye and the right eye of a user, the two test images respectively have a test mark, and the spacing between the two test marks is gradually increased or gradually reduced; the image acquisition unit is used for acquiring images in both eyes of the user, and the interpupillary distance analysis unit is used for getting the critical moment when the interpupillary distance changes according to images in the eyes of the user when the user watches the test images and determining the image spacing according to the spacing between the two test marks at the critical moment. In addition, the critical moment is a moment that the interpupillary distance stops increasing gradually and becomes stable or a moment that the interpupillary distance stops being stable and starts to reduce gradually.

Description

technical field [0001] The invention belongs to the technical field of head-mounted displays, and in particular relates to a binocular head-mounted display device and an image spacing adjustment method thereof. Background technique [0002] Head Mount Display (HMD, Head Mount Display), also known as glasses display device, video glasses, portable theater, etc., is a display device that is directly worn in front of the user's eyes in the form of a helmet or glasses. The head-mounted display device can be divided into binocular type and monocular type. The monocular type head-mounted display device only provides images for one eye of the user, while the binocular type head-mounted display device provides different images for both eyes of the user. [0003] Such as figure 1 As shown, the binocular head-mounted display device includes two display units 1 (such as liquid crystal displays) for generating display images, which respectively provide images for the user's left eye 8 ...
