Embodiment Construction
[0056] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0057]Figure 1a It is the display principle of AR-HUD, which uses augmented reality imaging technology to overlay digital images in the real world we see, so that the information projected by the head-up display can be integrated with the real driving environment. As shown in Figure 1, a virtual image is generated at the virtual image plane throug...

The embodiment of the invention relates to the technical field of head-up reality, in particular to a virtual image calibration method based on augmented reality head-up display, and the method comprises the steps: enabling an optical machine to generate a virtual image; moving the camera device and the curtain to enable the curtain and the virtual image to coincide at a first position, and obtaining an image shot by the camera device at the moment; obtaining window position information of the virtual image according to the image; and according to the position of the camera device, the first position and the window position information of the virtual image, obtaining a corresponding relationship between a virtual position and a real object position. According to the embodiment of the invention, the curtain and the virtual image are overlapped by moving the camera device and the curtain, so that the window position information of the virtual image is obtained. And then according to theposition of the camera device, the overlapping position of the curtain and the virtual image, and the position information of the window, obtaining the corresponding relationship between the virtual position on the virtual image and the position of the real object in the real scene. Calibration steps are few, and procedures are simple.
Description
technical field [0001] The embodiment of the present invention relates to the technical field of head-up display, and in particular to a method for calibrating a virtual image based on an augmented reality head-up display, a control device and a head-up display device. Background technique [0002] Augmented Reality Head Up Display technology (AR-HUD, Augmented Reality Head Up Display) is widely used in the process of car driving. AR-HUD can make the virtual image seen by the driver through the windshield and the objects around the car or the road. The real scene overlaps to form the effect of augmented reality, so that the driver can observe the real environment and obtain prompt information at the same time, which is convenient for the driver to drive the car. [0003] AR-HUD needs to display the corresponding prompt information (graphics or text) at the corresponding position of the virtual image, so it is necessary to use the calibration method to check the correspondenc...
