Method and system for locating hotspot icons in 3D line roaming

Abstract

The invention discloses a line three-dimensional roaming hotspot icon positioning method and system. The method comprises the following steps: obtaining a total display time length of a hotspot icon,and screen width and height values, and mapping the time length and screen coordinates to a unified interval; manufacturing a controller 1 and a controller 2, wherein the controller 1 is used for generating an x coordinate positioning curve of the hotspot icon according to the x coordinate increment of the hotspot icon relative to a target point within a display time, the controller 2 is used forgenerating a y coordinate positioning curve of the hotspot icon according to the y coordinate increment of the hotspot icon relative to the target point within the display time, horizontal axes of thecontrollers 1, 2 represent time changes of the hotspot icon, and the vertical axes represent displacement changes of the hotspot icon relative to the x and y coordinates of the target point; and whenthe line roams into a hotspot icon display time period, displaying the hotspot icon, and positioning the hotspot icon to a target point area according to the positioning curve. By adoption of the line three-dimensional roaming hotspot icon positioning method and system disclosed by the invention, a relatively ideal tracking and positioning effect can be achieved can be achieved without using thecomplicated image capture technology.

Description

technical field [0001] The invention relates to a method and a system for realizing the location of a three-dimensional roaming hotspot icon of a line, and belongs to the field of network technology. Background technique [0002] With the development of virtual reality technology, the demand for virtual reality in all walks of life is also increasing. Virtual roaming is to present the actual or virtual scene on the user's computer or mobile device through computer graphics technology, so that people can visit and tour the scene. As one of the important branches of virtual reality technology, the application field covers a wide range. At present, virtual roaming implementation technology is mainly divided into the following two forms: [0003] 1) Real 3D scene roaming: use computer 3D graphics technology to realize virtual scene roaming. [0004] 2) Pseudo 3D video scene roaming: 3D rendering is used to render movies or real-time shooting movies, and roaming is realized by ...

Problems solved by technology

[0009] a. For the true 3D scene, because the true 3D has a three-dimensional coordinate system, it is easy to locate the target area in the three-dimensional space. However, the 3D space has the characteristics of being near large and far small. When the user is far away, the hotspot icon is too small to be seen. When the distance is too short, it will affect the user experience, even if it is adapted, there will be performance consumption problems

[0010] b. For pseudo 3D, the principle is based on video playback. Image tracking technology is required to locate the target area, which requires high performance consumption and high algorithm requirements. If the target area has a single color, there will be inaccurate positioning. For roaming, real-time display is required. Low-end devices don't perform well enough
