Abstract

The invention belongs to the technical field of computers, and discloses an application method of oblique photography modeling data in immersive display equipment. The method comprises the following specific steps: designing an oblique photography data generation scheduling module according to a visual system platform architecture of a flight simulator, and establishing a panoramic drawing platform software structure; preprocessing the massive oblique photography models by using a panoramic view real-time generation technology, and constructing view generation contents by using a texture mapping technology; and improving the visual content through a fast approximation anti-aliasing algorithm, and performing image processing. The combination of the preprocessing technology and the texture mapping technology can well solve the problem of delay or lag caused by real-time scheduling of a large-scale natural scene in the immersive display equipment, the resolution of a visual image is improved, and the quick approximate anti-aliasing processing is performed, and then the quality of visual contents is greatly improved.

Description

technical field [0001] The invention belongs to the field of computer technology, and in particular relates to an application method of oblique photographic modeling data in an immersive display device. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] The high-precision modeling of large-scale natural scenes is an important problem to be solved urgently for the visual system of flight simulators. At present, the industry mainly adopts artificial modeling based on satellite images and automatic 3D reconstruction technology of aerial oblique photography. Among them, the aerial oblique photography method realizes the modeling automation of large-scale natural environments. Compared with the traditional manual modeling method, it has the characteristics of high modeling production efficiency, ultra-high resolution, and good visual effects, and its technical maturity gradually reaches the industrial level. ...

AI Technical Summary

Problems solved by technology

However, the natural scenes in the flight simulation scene are complex and have a large amount of content data, which requires very powerful hardware support. Even if advanced scene scheduling algorithms are used, it is still difficult to avoid the problem of picture freeze caused by the limited computing power of the computer.

[0009] Second, the virtual reality headsets currently on the market are still immature and there is a lot of room for improvement

In addition, a lens with magnification function is placed between the human eye and the display. Therefore, when the experiencer watches the screen at a close distance, if the quality of the visual content is not high enough, it is easy to see the aliasing phenomenon during the viewing process. Produce screen door effect, thereby reducing the authenticity of the virtual environment experience and destroying the sense of immersion
