The present application discloses an image projection method, apparatus, device and storage medium and relates to the field of intelligent transportation, and the specific implementation thereof is: acquiring a first camera coordinate of an area to be calibrated in a camera coordinate system of an AR camera on a vehicle, where the area to be calibrated is located within a photographing range of the AR camera; acquiring a relative conversion relationship between a first extrinsic parameter matrix of the AR camera and a second extrinsic parameter matrix of a head-up display on the vehicle; determining, according to the first camera coordinate and the relative conversion relationship, a second camera coordinate of a projection symbol corresponding to the area to be calibrated in a coordinate system of the head-up display; and controlling, according to the second camera coordinate, the head-up display to project an image including the projection symbol.

A laminated glazing for a head-up display (HUD). The laminated glazing has an outer glass pane and an inner glass pane, which are bonded to one another via a thermoplastic intermediate layer. The intermediate layer in the vertical course (C) between a lower edge L and the upper U edge of the laminated glazing is variable at least in sections between two virtual points P1 and P2 taken along the vertical course (C). The calculated surface area (S) surrounded a straight line connecting a first value V1 defined by a position (d(1)) and a thickness (Tk(1)) of the virtual point P1 and the last value V2 defined by a position (d(2)) and a thickness (Tk(2)) of the virtual point P2 is above 10.000 mm×μm.

An apparatus may include a first emitter and a second emitter. The first emitter may be configured to emit visible light comprising first heads up display information to be displayed to a driver of a vehicle. The second emitter may be configured to emit infrared light comprising second heads up display information to be displayed to one or more rear seat passengers of the vehicle.

A test fixture (10) for heads-up windshields (12) wherein aspherical devices (26) compensate for complex curvatures and optical aberrations in a heads-up display surface (16) of the windshield. A movable test grid (20) adjusts the elevation of preferred camera settings and a pivotal mounting of the test grid (20) enhances ghost image reduction and improves camera image resolution. A filter (36) limits interference of secondary ghost images (caused by IR coatings) with compliance assessment of the windshield.

A heads-up display includes a windshield (10) with a standardized wedge profile and an embedded reflective polarizer (20) for p-polarised light and a display (40). The reflective polarizer is disposed between, and spaced apart from, opposing outermost first and second major glass surfaces (11, 12) of the windshield. The heads-up display forms a virtual image for viewing by the eye of a passenger. An image emitted by the display may include a first image ray emitted from a predetermined region of the display and incident on the outermost first major glass surface of the windshield at an angle of incidence greater than about 60 degrees, with at least 90% of the incident first emitted image ray polarized in a plane of incidence of the first emitted image ray.

An object of the present invention is to provide a half-mirror film for displaying a projection image having high adhesiveness, a laminated glass in which wrinkle generation of the half-mirror film is suppressed or furthermore has high adhesiveness, and an image display system using the laminated glass. The problem is solved by providing a half-mirror film for displaying a projection image including a transparent support; and a selective reflection layer reflecting light in a wavelength selective manner, in which the transparent support has an absolute value of 10 nm or less of an in-plane phase difference at a wavelength of 550 nm and a heat seal layer disposed on an opposite surface of a surface having the selective reflection layer, the heat seal layer contains a thermoplastic resin, and a mixed layer in which components of the transparent support and the heat seal layer are mixed is formed between the transparent support and the heat seal layer.

The present application discloses a method of displaying images on a vehicle. The method includes disclosing user information, including an image to be displayed, to an exchange application, transmitting the image to a controller configured to receive user information, instructing, by the controller, an electronic display to display the image to display the image to a viewer outside of the vehicle, and displaying the image, by the electronic display, to the viewer outside of the vehicle. The electronic display is disposed on or integrated into a window of the vehicle and configured to move in unison with the vehicle to display the image. The electronic display is configured to be transparent to a viewer inside of the vehicle. The controller is in communication with the electronic display.

A vehicle and a method for controlling the vehicle are provided. The vehicle includes a first camera configured to capture a front image of the vehicle; a head-up display configured to project an image onto a windshield of the vehicle; an input device configured to input a boundary line for setting an area in which the image is projected from the windshield; and a controller configured to determine a projection area in which the image is projected based on the inputted boundary line, to determine an interest area of the front image based on the determined projection area and a speed of the vehicle, and to display the determined interest area in the determined projection area on the head-up display.

A display system which controls a display of display content, includes: a processor; and a memory having stored thereon instructions executable by the processor. The instructions includes: performing image correction involving a change in a display position of the display content based on image correction data stored in advance; detecting an attitude change amount of a moving body; calculating, after the image correction is performed, a vibration correction amount of the display position of the display content based on the attitude change amount of the moving body and an image correction error of the image correction caused by vibration correction processing of correcting a display deviation caused by an attitude variation of the moving body; and controlling the display position of the display content based on the vibration correction amount.
