Abstract

The invention relates to the technical field of teaching systems, and, more specifically, relates to an AR (augmented reality) CAD teaching method and system. The teaching method mainly comprises thesteps: building a three-dimensional model through 3D software, importing a stereoscopic model, a model graph and three views into three-dimensional animation software, carrying out the collection of two-dimensional images in a classroom through a camera, carrying out the recognition through the three-dimensional animation software, exporting a three-dimensional stereoscopic model file, and displaying the three-dimensional stereoscopic model file, wherein the display mode can be changed so as to observe the three-dimensional stereoscopic model at multiple angles. The teaching system comprises aplatform main body, and a computer and a display mounted on the platform main body. The platform main body is provided with a camera, a gesture sensor and a projector, wherein the camera, the gesturesensor and the projector are electrically connected with the computer. The method and system employ the AR mode, also can achieve the real-time interaction through gestures, achieve the conversion between the two-dimensional images of the classroom and the three-dimensional mode, bring convenience to students for quickly building a three-dimensional model stereo architecture, and help students create 3D thinking.

Description

technical field [0001] The invention relates to the technical field of teaching systems, and more specifically, to an augmented reality CAD teaching method and a teaching system. Background technique [0002] At present, most engineering majors in many universities and vocational colleges at home and abroad offer CAD-related courses. The main purpose of CAD classroom teaching is to enable students to master the necessary theoretical knowledge within a limited teaching time, learn to understand diagrams, and draw different requirements. The 3D model diagram and its cutaway diagrams in different planes. At present, most schools use multimedia platforms and CAD software for teaching, but most of the multimedia platform teaching lacks a complete construction process for the abstract part of the content, and students' cognitive senses can only stagnate on a two-dimensional plane. The 3D model in CAD also has a 3D solid effect, but essentially it shows a plane, and students canno...
