AI Technical Summary

Benefits of technology

This patented technology describes how a simplified version of a flight simulator (FSS) called Aeronautical Virtual Sand Table System was developed for reducing complex displays on buildings during training sessions. It achieves this by simplifying its construction without requiring any extra hardware like head mounted monitors or depth cameras. Its technical feature includes displaying images from different angles at once instead of just showing them all over again when they are displayed next after being captured. Additionally, there were no physical constraints placed upon these systems making their installation less complicated than previous designs. Overall, this new type allows users to see things clearly even if only looking around constantly.

Problems solved by technology

In this patented technical problem addressed by this patents are how to create an immersive experience that can be visually simulated through computer-generated graphics (CG). Current methods require complex hardware or involve complicated software processes which increase costs while still providing limited flexibility with regards to scenes being mapped onto screens during simulation time.

Embodiment 1

[0038] A virtual sand table system in the air, such as figure 1 and figure 2 As shown, the technical solutions adopted are as follows:

[0039] The air virtual sand table system includes:

[0040] A sand table pattern import module for importing the complete sand table pattern to be displayed into the air virtual sand table system;

[0041] A device quantity detection module used to detect the number of display devices required for the scene;

[0042] A device quantity judging module for judging whether the number of display devices satisfies the display of the sand table pattern based on the total size of the sand table pattern;

[0043] An equipment numbering module for numbering the display equipment after the equipment quantity judging module judges that the quantity of the display equipment satisfies the display of the sand table pattern;

[0044] After the equipment quantity judging module judges that the number of displayed equipment does not satisfy the display of...

Embodiment 2

[0053] A method for displaying virtual sand table in the air, such as image 3 As shown, the technical solutions adopted are as follows:

[0054]The air virtual sand table display method includes:

[0055] A sand table pattern import step for importing the complete sand table pattern to be displayed into the aerial virtual sand table system;

[0056] A device quantity detection step for detecting the number of display devices required for a scene;

[0057] A step for judging the number of devices on display according to the total size of the sand table pattern whether the number of display devices satisfies the display of the sand table pattern;

[0058] An equipment numbering step for numbering the display equipment after the equipment quantity judging step determines that the number of the display equipment satisfies the display of the sand table pattern;

[0059] After the step of judging the number of devices judges that the number of displayed devices does not meet the...

Embodiment 3

[0066] A method for displaying virtual sand table in the air, such as image 3 and Figure 4 As shown, the technical solutions adopted are as follows:

[0067] Step 1: Import the map of China into the system;

[0068] Step 2: The number of display devices required to detect the scene is 15;

[0069] Step 3: Judging whether the number of display devices can meet the map pattern display according to the total size of the sand table pattern, the pattern size is 9 meters wide and 15 meters long, and the pattern block size that can be displayed by one device is 3 meters wide and 3 meters long, so A total of 15 devices are required to meet the judgment requirements; proceed to the next step

[0070] Step 4: Number the display equipment from 1 to 15;

[0071] Step 5: Divide the map pattern into 15 blocks according to the number of display devices;

[0072] Step 6: Assign the divided pattern blocks to each device according to the number 1 to 15 of the display device;

[0073] St...
