Problems solved by technology

However, in the current design methods that are widely used in various mainstream 3D design software, designers still design in a two-dimensional plane area, and generally only provide users with three views, which affects the designer's spatial imagination and three-dimensional Geometry has high requirements, and designers often need to spend a lot of time and energy thinking and calculating the relative relationship of the designed objects in space; and mainly use traditional human-computer interaction methods - based on input devices such as mouse and keyboard Editing and operation, based on the visual feedback of the flat-panel display, the disadvantage of this traditional design method is that the operation efficiency is low and not intuitive enough, and the user has no sense of immersion

Embodiment 1

[0071] The real three-dimensional design method based on augmented reality interactive technology includes the following steps:

[0072] 1): Initialize the system environment, set system parameters, scan and check system equipment;

[0073] 2): Design an algorithm to calibrate the binocular camera fixed on the helmet display, and use it to collect real scenes to obtain the original video image;

[0074] 3): Design an algorithm to correct the error of the magnetic tracker, and use the corrected tracking data to complete the real-time orientation tracking of the designer's head and hands and the three-dimensional registration of the virtual model;

[0075] 4): The design algorithm normalizes the data glove, and uses the normalized data to obtain the bending state of the designer's finger in real time;

[0076] 5): The design algorithm recognizes the human-computer interaction operation of the designer in real time, analyzes and processes the hand orientation tracking data and f...

Embodiment 2

[0125] Such as figure 1 As shown, this true 3D design method based on augmented reality interactive technology specifically includes the following on-machine operation steps:

[0126] Step 1): the system starts to run;

[0127] Step 2): device initialization;

[0128] Step 3): the user starts;

[0129] Step 4): magnetic tracker correction;

[0130] Step 5): data glove correction;

[0131] Step 6): real scene acquisition and processing;

[0132] Step 7): open / create a new design document;

[0133]Step 8): state selection, if select " draw ", then continue, if select " edit ", then go to step 12);

[0134] Step 9): select drawing tool;

[0135] Step 10): real-time drawing;

[0136] Step 11): select whether to edit the object, if select "Yes", then continue, if select "No", then go to step 21);

[0137] Step 12): collision detection;

[0138] Step 13): whether there is a collision, if there is a collision, then continue, if there is no collision, then go to step 12); ...

Abstract

The invention relates to a true three-dimensional design method based on the augmented reality interaction technology. The true three-dimensional design method is the technology which organically integrates the augmented reality and the computer three-dimensional design together for the first time. The invention actually provides a new design development concept that a work area of a designer is expanded from a two-dimensional plane to a true three-dimensional space region, and the augmented reality technology is adopted to carry out man-machine interaction and feedback display to enable a user to carry out the design and development work in the shocked immersion sense. Along with the high-speed development of the multimedia technology, the true three-dimensional design method becomes an inevitable trend and inevitably causes a change of the development field of a computer aided design platform.

Description

technical field [0001] The present invention relates to a true three-dimensional design method, specifically a true three-dimensional design method based on augmented reality interactive technology. Background technique [0002] Augmented reality technology (Augmented Reality, AR) is a new technology that "seamlessly" integrates real world information and virtual world information, which emerged with the rapid development of virtual reality technology (Virtual Reality, VR) and the needs of practical applications. The ultimate goal of AR technology is to use computer graphics technology, visualization technology, interactive technology, display technology, etc. to generate virtual objects that do not exist in the real environment, and to accurately "place" the virtual objects in the real environment through registration technology, so that Users are in an environment where the virtual and real worlds are seamlessly integrated. Although both seek to give users a feeling of be...
