Problems solved by technology
In web browsing, there are usually many controls on a webpage, such as a webpage with many text input boxes. For ordinary users, it is difficult to accurately fill in each text input box.
Especially with the development of augmented reality technology, users will use AR glasses to browse the web. If you want to fill in the text input box in the web page in the AR display interface, it is often difficult to fill in due to spatial positioning errors.

Embodiment Construction
[0053] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, and are only for explaining the embodiments of the present invention, and should not be construed as limiting the embodiments of the present invention.
[0054] Such as figure 1 As shown, the present invention takes the upper left corner of the display screen as the origin, extends to the right as the positive X direction, extends downwards as the positive direction of the Y axis, and points to the inside of the display as the positive direction of the Z axis.
[0055] Next, introduce the establishment of the real world coordinate system xyz. Such as figure 1 , the uvw coordinate system is the coordinate system of the virtual w...

The invention relates to the field of augmented reality, and relates to a spatial positioning method for a web page widget in AR. The method comprises the following steps: obtaining the visual windowcoordinates of the control in a PC browser according to the page coordinates of the control on the web page; obtaining the browser coordinates of the control in the browser according to the coordinates of the visual window; the screen coordinates of the control on the PC display screen are calculated according to the browser coordinates and the origin of the browser coordinates. The real world coordinates of the control in the real world are calculated according to the screen coordinates. According to the real world coordinates, the coordinates of the corresponding points of the control projection on the camera projection plane of the AR device are calculated by using the preset three-dimensional registration algorithm to complete the spatial positioning. The invention also provides an ARsystem. By acquiring and transforming the coordinate information of the web page widget in a plurality of coordinate systems, the invention ensures that the web page widget can realize accurate spatial positioning in the AR.
Description
technical field [0001] The invention relates to the field of augmented reality, in particular to a spatial positioning method and an AR system for web page controls in AR. Background technique [0002] Augmented Reality (AR for short) is a technology that calculates the position and angle of camera images in real time and adds corresponding images, videos, and 3D models. The goal of this technology is to put the virtual world on the screen. the real world and interact with it. [0003] With the development of AR technology, there are more and more interactions between AR and the Internet. In web browsing, there are usually many controls on a webpage. For ordinary users, it is difficult for ordinary users to accurately fill in each text input box on a webpage with many text input boxes. Especially with the development of augmented reality technology, users will use AR glasses to browse the web. If you want to fill in the text input box in the web page in the AR display inte...
