Problems solved by technology

Because designers are still designing in a two-dimensional plane area, users cannot personally enter this work area to view and feel the objects being designed, which puts higher demands on designers' spatial imagination and solid geometry. Designers often need to spend a lot of time and energy to think and calculate the relative spatial relationship of the designed objects; and these systems or platforms mainly use traditional human-computer interaction methods - based on input devices such as mouse and keyboard. Editing and operation, the disadvantage of this method is that the operation is inefficient and not intuitive enough, and the user has no sense of immersion

Embodiment 1

[0079] see figure 1 , the present invention is based on a conceptual diagram of the structure of a real three-dimensional modeling system based on video perspective augmented reality technology. The system uses a magnetic tracker to track the user's viewing angle and hand pose changes in real time, and the original user interaction information read by the electromagnetic tracking system and the data glove is analyzed, calculated and processed on PC6; the main tasks of PC2 include receiving information from PC6. According to the data information such as the user's viewpoint position and design operation, the virtual camera position is calculated, and the drawing and registration of the virtual scene corresponding to the left and right eyes are completed accordingly; PC4 and PC5 receive the two channels of real scene video and The virtual scene transmitted from PC2 is seamlessly and naturally blended and rendered; finally, all the hosts are interconnected through high-speed Eth...

Embodiment 2

[0081] see figure 2 , the present invention is based on a true three-dimensional modeling method of video perspective augmented reality technology, and uses the above-mentioned system for modeling, and is characterized in that: firstly, by taking a logo picture, using digital image technology to obtain the internal parameters and external parameters of the camera, and completing the camera calibration ; Then use the calibrated camera and video capture card to collect the real scene, laying the foundation for the subsequent fusion of virtual and real; use the improved linear regression model to correct the real-time collected data of the user's head, hand and five finger bending, reduce the The error caused by the measurement; finally, let the user watch the effect of virtual and real fusion through the video see-through HMD and perform interactive operations.

Embodiment 3

[0082] Example Three: Participate image 3 , the present invention is based on the true 3D modeling system and method of video perspective augmented reality, specifically including the following components:

[0083] First of all, design users perform modeling and design work in a real-world 3D workspace, and the designed objects are presented to users in the form of virtual objects, and the virtual and real scenes are perfectly integrated through video perspective augmented reality technology.

[0084] Utilize webcams and video capture cards to capture real-world scene video. Fix the camera on the head-mounted display, and simulate the user's eyes so that it can shoot images similar to those observed by the human eye. Therefore, the two cameras CAM1 and CAM2 need to have greater flexibility so that they can be adjusted continuously to obtain a more satisfactory result. image. What we use is the LCH-P49A industrial camera of CBC Company, which has backlight compensation, auto...

Abstract

The invention relates to a true 3D (three dimension) modeling system and method based on video perspective type augmented reality, namely a technology organically combining a video perspective type augmented reality technology and computer 3D modeling for the first time. With the rapid development of a multi-media technology, the true 3D design method becomes an inescapable trend, and a new revolution is bound to occur in the fields of computer auxiliary modeling and design platform development. In fact, a fully novel design development concept is proposed in the invention. A work area of a designer is expanded from a 2D plane to a true 3D space zone. The limitation that 3D modeling can only be carried out in the 2D plane previously is relieved, the design efficiency is increased, and the design flow is simplified. Due to the application of the augmented reality technology in human-computer interaction and feedback display, a user can be deep immersed in design development and fully enjoy unrestrained and vigorous creating pleasure.
