Problems solved by technology

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

Embodiment Construction

[0016] Use FPGA-EPIC12 to realize 1280~1024 three-dimensional visual image memory and two 800~600 display memories; store the division and overlapping parts of two projector display storage areas in FPGA; store the storage unit for three-dimensional visual image storage according to The display and storage areas of the two projectors that have been divided in advance are directly connected, and the synchronization signal is used for assignment control; The divided display storage area is assigned; the three-dimensional visual image memory automatically updates the address corresponding to the output of each projector display storage, and waits for the next synchronization signal to continue assigning each projector display storage area until the assignment is completed; all projections After the assignment of the storage area of ​​the projector display is completed, the FPGA uses synchronous control of the display to realize the fast and synchronous display of the two project...

Abstract

The invention provides a direct assignment display method in a true three-dimensional simulation area. The method comprises the following steps of: directly connecting storage units of a three-dimensional visual image memory with pre-divided display storage areas of each projector, and performing assignment control by using synchronizing signals; assigning the contents, corresponding to the display storage areas of each projector, of the three-dimensional visual image memory to all pre-divided display storage areas at the same time according to the synchronizing signals; and when the assignment of the display storage areas of all projectors is completed, synchronously controlling the display to realize the rapid and synchronous display of a plurality of projectors. By the method, the assignment and the image call of the divided display areas are realized on line by hardware; the rapid and synchronous display of the plurality of projectors is realized reliably; and the problem of the simulation speed bottleneck of 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, it was proposed based on computer, graphics and image processing, multi-sensor, network and man-machine programming [0003] The comprehensive simulation technology 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 vision simulation technology, and it is the crystallization and reflection of highly developed computer technology in various fields. It not only includes graphics, image processing, pattern recognition, network T...
