Method for directly assigning and displaying true three-dimensional simulation regions

Abstract

The invention provides a method for directly assigning and displaying true three-dimensional simulation regions. The method comprises the following steps of: directly connecting a storage unit of a three-dimensional visual image storage with a display storage region of each projector, which is divided in advance, and carrying out assignment control by a synchronous signal; simultaneously assigning all the display storage regions which are divided in advance by contents which are stored in the three-dimensional visual image storage and respectively correspond to the display storage region of each projector according to the synchronous signal; and after completing assigning the display storage regions of all the projectors, synchronously controlling and displaying to realize rapid and synchronous display of a plurality of projectors. By the method, on-line assignment and image calling of the divided display regions are realized by hardware, rapid and synchronous display of a plurality of projectors is reliably realized and the problem of the speed bottleneck of a method for performing simulation by a software method is solved.

Description

technical field [0001] The invention relates to a direct assignment and display method of a true three-dimensional simulation area, belonging to the technical field of true three-dimensional simulation and parallelism. Background technique [0002] True 3D simulation has important applications in aviation, aerospace, transportation and other fields, and has always been valued by scientific researchers. As early as 1960, people proposed a comprehensive simulation technology based on computers, graphics and image processing, multi-sensors, networks and ergonomics, 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, Networ...

Problems solved by technology

However, since true 3D simulation requires spherical nonlinear distortion correction and requires multiple projectors to be stitched together, issues such as image calling, assignment of video memory to each projector, and synchronization of multi-channel images make it difficult to guarantee real-time performance.
