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 spatia

Example Embodiment

[0078] Example one:

[0079] See figure 1 , The present invention is a conceptual diagram of the structure composition of a true three-dimensional modeling system based on video perspective augmented reality technology. The system uses a magnetic tracker to track the user's perspective and hand posture changes in real time. The original user interaction information read by the electromagnetic tracking system and data gloves is analyzed, calculated and processed with algorithms on PC6; the main tasks of PC2 include receiving PC6. The user’s viewpoint position, design operation and other data information, calculate the virtual camera position, and complete the drawing and registration of the virtual scene corresponding to the left and right eyes respectively; PC4 and PC5 receive the two channels of real scene video and The virtual scene transmitted by PC2 is rendered seamlessly and naturally. Finally, all hosts are interconnected through high-speed Ethernet and run cooperatively u...

[0080] Embodiment two:

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

[0082] Example 3: Participate image 3 , The present invention is based on the true three-dimensional modeling system and method of video see-through augmented reality, which specifically includes the following components:

[0083] First of all, the design user is modeling and designing in a real-world three-dimensional workspace, and the designed objects are presented to the user in the form of virtual objects, and the virtual and real scenes are perfectly integrated through the video perspective augmented reality technology.

[0084] Use the camera and video capture card to video the real world scene. Fix the camera on the head-mounted display to simulate and design the user's eyes to capture images similar to those observed by the human eye. Therefore, the two cameras CAM1 and CAM2 need to have greater flexibility in order to be able to continuously adjust to achieve a satisfactory image. What we use is the LCH-P49A industrial camera from CBC, which has functions such as backl...

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.

Description

technical field [0001] The present invention relates to a true three-dimensional modeling system and method, specifically a true three-dimensional modeling system and method based on video perspective augmented reality. Background technique [0002] 3D modeling is a new technology that combines graphics, geometry, dynamics, physics and other disciplines with multimedia computer as a tool.
