A system and method of detecting display fit measurements and/or ophthalmic measurements for a head mounted wearable computing device including a display device is provided. An image of a fitting frame worn by a user of the computing device is captured by the user, through an application running on the computing device. One or more keypoints and/or features and/or landmarks are detected in the image including the fitting frame. A three-dimensional pose of the fitting frame is determined based on the detected keypoints and/or features and/or landmarks, and configuration information associated with the fitting frame. The display device of the head mounted wearable computing device can then be configured based on the three-dimensional pose of the fitting frame as captured in the image.

The first attachment may include an engaging portion capable of engaging with a use's head and a first attaching portion that attaches the engaging portion to the joint portion. The second attachment may include a fixing portion fixable to headwear covering the user's head and a second attaching portion that attaches the fixing portion to the joint portion.

A head-mounted display includes an image display device displaying an image, a mounting member that is fixed to a head of a user, a first ball joint capable of moving and holding the image display device relative to the mounting member and a second ball joint. The first ball joint can move the image display device relative to the mounting member with a first degree of freedom or a third degree of freedom smaller than the first degree of freedom. A socket can selectively change a degree of freedom of the first ball joint between the first degree of freedom and the third degree of freedom.

A headset includes a housing, an optical assembly disposed in the housing, and an adjustment assembly coupling the optical assembly to the housing. The optical assembly includes a first lens and a second lens spaced from the first lens by a first distance. The adjustment assembly includes an interpupillary distance adjustment mechanism and an eye relief distance adjustment mechanism. The interpupillary distance adjustment mechanism is configured to adjust the first distance between the first lens and the second lens along a first axis. The eye relief distance adjustment mechanism configured to adjust the optical assembly a second distance along a second axis orthogonal to the first axis.

A head-up display apparatus includes: an image display apparatus generating image light to be projected; an optical system performing predetermined correction to the image light emitted from the image display apparatus; and a concave mirror reflecting the image light corrected by the optical system to project it onto a windshield or combiner. The image display apparatus includes: a solid light source; a collimating optical system converting, into parallel light, the light from the solid light source; a lighting optical system configured by an optical member that polarizes a direction of a light beam generated by the collimating optical system and simultaneously expands a width of the light beam; and a display apparatus, the image display apparatus being configured to be arranged across and opposite the optical system on an optical axis of the concave mirror.

Embodiments of this application relate to the technical field of optical design, and disclose a method for adjusting field of view angle applied to a waveguide plate in a near-eye display equipment, the waveguide plate forms a tilt angle relative to horizontal direction of human face, the method firstly acquires refractive index, bottom angle of the waveguide plate and a required field of view angle, then calculates the tilt angle of the waveguide plate according to the refractive index and bottom angle of the waveguide plate and the field of view angle, and finally, adjusts the tilt angle to make sure the near-eye display equipment with the field of view angle; the method disclosed by this application enables the waveguide plate to realize low refractive index and large field of view angle at the same time, and features better imaging, lower cost and better stability.

A control method for an imaging system is provided. The imaging system includes a display device and a dimming lens disposed on a display side of the display device. The dimming lens is capable of moving toward or away from the display apparatus to adjust an object distance from the display device to the dimming lens. The control method includes: determining the object distance when the dimming lens moves to a set position; according to the object distance, determining an image distance from a virtual image, generated by a display image of the display device through the dimming lens, to the dimming lens; and according to the determined image distance and a correlation between the image distance and a resolution of the display image, determining a resolution corresponding to the determined image distance, and controlling the display device to display the display image at the determined resolution.

A head-up display includes a display panel, a reflective optical element, a controller, and an obtainer. The display panel displays a first image. The reflective optical element reflects image light from the first image displayed by the display panel. The controller controls a position at which the first image is displayed on the display panel. The obtainer obtains, as positional information, a position of an eye of a user. The controller changes the position at which the first image is displayed on the display panel in accordance with the positional information.

A head-up display system includes a first projection module that projects a first image to display the first image in a forward direction not directly facing a user, a second projection module that projects a second image to display the second image in a forward direction directly facing the user, and a reflective optical element that reflects at least a part of the first image and at least a part of the second image.
