Problems solved by technology

[0007] The technical problem of the present invention is to overcome the deficiencies of the prior art and provide a control method for virtual 3D display on a 2D screen based on environmental sensors (hereinafter referred to as the 2D virtual 3D method). The cost of the screen and equipment limitations make it impossible to popularize the 3D visual experience. The existing 2D flat-panel electronic display equipment is fully utilized to save costs while allowing users to obtain a better visual experience.

Embodiment Construction

[0029] The technical solutions of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] Such as figure 1 Shown, the specific implementation steps of the present invention are as follows;

[0031] Ensure that the graphical program interface, environmental sensors, etc. are initialized successfully and can be called normally.

[0032] Step 1) Establish a Cartesian coordinate system for the screen, which is usually defined as follows: the X axis is parallel to the plane where the screen is located and points to the intuitively upward direction, the Y axis is parallel to the plane where the screen is located and points to the intuitively right The plane is vertical and pointing to the user side is the z-axis, and the center of the screen (generally the center of gravity) is the origin. The X axis, the Y axis, and the Z axis form a right-handed coordinate system. Obtain initial data for ea...

Abstract

The invention discloses a control method for realizing virtual 3D (3-dimension) display on a 2D (2-dimension) screen on the basis of an environment sensor. The method is characterized in that the technology utilizes the embedded environment sensor of electronic equipment to obtain the positions of the eyes of a user relative to a display screen through calculation, the coordinate conversion is carried out through an equation to obtain the image coordinates of objects displayed on the display screen, and in addition, the results are introduced into a pattern program interface to be bloated and displayed, so the operator in the corresponding observation position can feel the virtual 3D imaging effect. Through using the method, the problem that the 3D visual perception cannot be popularized because of limitation of the manufacturing cost of the 3D screen and the equipment in the existing market is solved, the existing 2D plane electronic display equipment in the prior art is sufficiently utilized, the cost is saved, and meanwhile, the user obtains better visual experience.

Description

technical field [0001] The invention relates to a screen display control method, in particular to a control method for virtual 3D display on a 2D screen based on environmental sensors. Background technique [0002] With the continuous development of the computer field, in today's informatization, the application of computers is not limited to flat display methods. From the release of 3D movies to the continuous appearance of naked-eye 3D screens, the computer field will usher in a shift from 2D to A new twist in 3D. [0003] Through the application of 3D technology in the market, it is not difficult to find people's demand for 3D technology experience. First of all, 3D technology is different from conventional two-dimensional flat display technology. Through the improvement of equipment and display effects, it creates a realistic visual effect, allowing users to achieve a real and good user experience. In addition, the application of 3D in the movie market and game market ...
