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
The present invention relates to the indirect assignment display packing in a kind of true three-dimensional artificial zone, belong to true three-dimensional artificial and concurrent technique field.
Background technology
True three-dimensional artificial all has important use in fields such as Aeronautics and Astronautics, traffic, is paid attention to by scientific research person always.As far back as nineteen sixty, people have just proposed based on computing machine, graph and image processing, multisensor, and the comprehensive simulating of network and human engineering technology is expressed as " virtual reality " (or virtual environment, face the border, clever border etc.) usually.In a sense; Virtual reality technology is the extension of computing machine Scene Simulation; Be crystallization and the reflection of computer technology in the application process in various fields of high development; It not only comprises high-performance calculation technology such as graphics, Flame Image Process, pattern-recognition, network technology, parallel processing technique, artificial intelligence, and relates to fields such as mathematics, physics, communication, even relevant with subjects such as meteorological, geographical, aesthetics, psychology and sociologys.The rise of virtual reality technology is for new research field has been started in the development of human-computer interaction interface, for the application of intelligence engineering provides new interface tool, for the large-scale data visualization of all kinds of engineerings provides new describing method.When needs are handled a large amount of abstract datas; This The Application of Technology; Improved people and utilized computing machine to carry out the mode that project data is handled, obtained in fields such as military affairs, medical science, design and amusements using widely, and brought huge economic benefit.
In recent years, very three-dimensional 360 ° of panorama emulation become the focus of virtual reality emulation personnel research.Because of its big field range, high-immersion, the visual effect that has more telepresenc has obtained more concern based on the analogue system of spherical projection.Yet, because true three-dimensional artificial need carry out the sphere correction of non-linear distortions, and need a plurality of projector splicings, image call, make for the problem such as synchronous of each projector video memory assignment, multichannel image in fact to be difficult to guarantee real-time.
Summary of the invention
In order to improve online viewing area assignment and image call speed to dividing; The present invention proposes the indirect assignment display packing in a kind of true three-dimensional artificial zone; This method with the storage unit of three-dimensional vision video memory with directly link to each other according to the demonstration storage area of ready-portioned each projector in advance; Give all ready-portioned in advance viewing areas (showing storage) assignment with the corresponding content of demonstration storage area that leaves three-dimensional vision video memory and each projector in simultaneously according to synchronizing signal, realize that the quick, synchronous of a plurality of projector shows;
The present invention solves the technical scheme that its technical matters adopts, the indirect assignment display packing in a kind of true three-dimensional artificial zone, and its characteristic may further comprise the steps:
1 with the storage unit of three-dimensional vision video memory with directly link to each other according to the demonstration storage area of ready-portioned each projector in advance, carry out assignment control with synchronizing signal;
2 will leave three-dimensional vision video memory and each projector in the corresponding content of demonstration storage area give all ready-portioned in advance demonstration storage area assignment simultaneously according to synchronizing signal;
Automatically upgrade the address that shows the corresponding output of storage with each projector in the 3 three-dimensional vision video memories, wait for that next synchronizing signal continues each projector is shown the storage area assignment, finish until assignment;
After 4 all projector showed that the storage area assignment is accomplished, synchro control showed, realizes that the quick, synchronous of a plurality of projector shows.
Principle of the invention structured flowchart such as Fig. 1, shown in Figure 2.
The present invention has realized online viewing area assignment and image call to dividing through hardware, reliably realizes quick, the demonstration synchronously of a plurality of projector, has solved software approach simulation speed bottleneck problem.

Fig. 1 is the indirect assignment display packing structured flowchart in the true three-dimensional artificial of the present invention zone;
Fig. 2 is that the three-dimensional vision video memory shows the storage area assignment graph for each projector;
Fig. 3 is that the three-dimensional vision video memory shows the enforcement structural drawing of storage area for 2 projector.
Embodiment
Adopt FPGA-EP1C12 to realize 1280*1024 three-dimensional vision video memory, 2 800*600 display-memories; In FPGA, deposit division and intersection that two projector show storage area; With the storage unit of three-dimensional vision video memory with directly link to each other according to the demonstration storage area of ready-portioned two projector in advance, carry out assignment control with synchronizing signal;
Give all ready-portioned in advance demonstration storage area assignment with the corresponding content of demonstration storage area that leaves three-dimensional vision video memory and each projector in simultaneously according to synchronizing signal;
Automatically upgrade the address that shows the corresponding output of storage with each projector in the three-dimensional vision video memory, wait for that next synchronizing signal continues each projector is shown the storage area assignment, finish until assignment;
After all projector showed that the storage area assignment is accomplished, FPGA showed with synchro control, realizes that the quick, synchronous of 2 projector shows.
The example block diagram of practical implementation is as shown in Figure 3.
