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.

Embodiment Construction

[0015] Use FPGA-EP1C12 to realize 1280*1024 three-dimensional visual image memory and two 800*600 display memories; store the division and overlap of two projector display storage areas in FPGA; combine the storage unit of three-dimensional visual image memory with The display storage areas of the two pre-divided projectors are directly connected, and the synchronization signal is used for assignment control;

[0016] The content stored in the 3D visual image memory corresponding to the display storage area of ​​each projector is assigned to all pre-divided display storage areas at the same time according to the synchronization signal;

[0017] Automatically update the output address corresponding to each projector display storage in the 3D visual image memory, and wait for the next synchronization signal to continue assigning values ​​to each projector display storage area until the assignment is completed;

[0018] After the assignment of the display storage area of ​​all projector...

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 display method of a true three-dimensional simulation area, belonging to the field of true three-dimensional simulation and parallel technology. 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 put forward comprehensive simulation technology based on computer, graphics and image processing, multi-sensor, network and ergonomics, usually expressed as "virtual reality" (or virtual environment, environment, spiritual environment, etc.). In a sense, virtual reality technology is an extension of computer vision simulation technology, and is the crystallization and reflection of highly developed computer technology in various fields. It not only includes graphics, image processing, pattern recognition, Network technology, parallel processing technology, artif...
