A 3D drawing system and method based on human-computer interaction

Abstract

The invention provides a three-dimensional drawing system and a three-dimensional drawing method based on human-computer interaction. The method comprises the following steps: determining the working plane of a pair of smart glasses through a plane recognition unit of the smart glasses; tracking the head position of a wearer of the smart glasses through a locating and tracking unit, and adjusting an image, superimposed on the working plane, of the smart glasses in real time according to the head position to keep the wearer and the image relatively static; using an interactive pen to draw a two-dimensional graph on the interface of a piece of three-dimensional drawing software; processing the two-dimensional graph to form a three-dimensional graph; using the interactive pen to control the three-dimensional graph to be away from the interface of the three-dimensional drawing software and go into a three-dimensional space; and displaying the information of the three-dimensional graph through the smart glasses. According to the three-dimensional drawing system and the three-dimensional drawing method provided by the invention, the three-dimensional drawing software can be put in any plane. Therefore, three-dimensional model drawing can be carried out at any time and in any place, the freedom of drawing is enhanced, and users do not need to always work in front of a two-dimensional display. The three-dimensional drawing system and the three-dimensional drawing method are convenient and reliable.

Description

Technical field [0001] The invention relates to the field of image technology, in particular to a three-dimensional drawing system and method based on human-computer interaction. Background technique [0002] Although this type of 3D drawing software represented by SolidWorks, UG, ProE, etc. can help designers draw the required 3D model, this method has a fundamental shortcoming: all drawing work is done on a two-dimensional plane. , And the drawn model is three-dimensional. This drawing method is not intuitive for the user. At the same time, the current three-dimensional drawing software is completed on the computer, and the user is limited to complete the drawing operation in front of a two-dimensional display, which does not allow the designer to complete the design process at any time and anywhere. [0003] With the development of technology, smart glasses have gradually entered people’s field of vision. For see-through smart glasses, when a person wears such glasses, the surr...

Problems solved by technology

[0002] Such 3D drawing software represented by SolidWorks, UG, ProE, etc. can help designers draw the required 3D models, but this method has a fundamental disadvantage: all drawing work is done on a two-dimensional plane , but the drawn model is three-dimensional, which is not intuitive for users

[0004] Currently, all 3D modeling work is done on two-dimensional displays, and there is no technology capable of modeling in three-dimensional space
