Embodiment Construction

[0027] refer to Figure 1~4 , the present invention realizes the three-dimensional panorama simulation of 360° horizontally and 180° vertically, creates a realistic panorama environment close to reality for the observer, and can roam in real time inside the scene at the same time.

[0028] The whole panoramic simulation system consists of two parts, software and hardware, such as figure 1 shown. The scene generation part uses a professional graphics workstation for simulation image generation, nonlinear distortion correction, and scene scheduling management; the projection display part includes a spherical projection screen and projectors for each channel. The software system adopts the professional simulation modeling tool Creator and the visual simulation driver software Vega. In the environment of Microsoft Visual C++6.0, the model database is built and imported into the Multigen-Vega operating environment to realize interaction and visual simulation.

Abstract

The invention provides a simulation method for concurrent computation. The invention designs a visual-view transformation and multi-channel display controller. The method comprises the following steps of: presetting a display and storage units corresponding to projectors in Ramdisk according to different projection curves of all projectors in three-dimensional space; sending each extracted frame plane figure to an image processor from an interface of a visual-view generating system; processing each extracted frame plane figure by the image processor to realize the three-dimensional transformation and nonlinear distortion correction of the plane figures from plane projection to a spherical surface; then synchronously writing zones corresponding to the three-dimensional curves into the Ramdisk display and storage unit corresponding to each projector according to the three-dimensional curves corresponding to all projectors according to refreshing signals to accomplish three-dimensional display. The design scheme for image processing operation and display output control in a concurrent computation mode greatly improves the processing speed of the system and ensures the requirement of a virtual reality simulation system on real-time performance.

Description

technical field [0001] The invention relates to a 360° spherical display panorama simulation system adopting a parallel computing method. Background technique [0002] Virtual reality technology is a comprehensive technology based on computers, graphics and image processing, multi-sensors, networks and ergonomics proposed in the 1960s. It is usually expressed as "virtual reality" (or virtual environment, virtual environment, spiritual environment, etc.). In a sense, virtual reality technology is an extension of computer visual simulation technology, and it is the crystallization and reflection of highly developed computer technology in the application process of various fields. It not only includes graphics, image processing, pattern recognition, Network technology, parallel processing technology, artificial intelligence and other high-performance computing technologies, and involve mathematics, physics, communication and other fields, and even related to meteorology, geogra...
