Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] The invention is a method for making a virtual experiment of convex lens imaging, including a video capture process, a virtual-real fusion process, and an interactive display process. The production process is as follows: figure 1 shown. The specific steps are as follows:

[0030] (1) Make a sliding guide rail plate with three movable blocks, and place three marking cards on the movable blocks;

[0031] Make a long plywood, which is composed of two long wooden boards, the two ends of which are fixed by short wooden strips of a certain thickness, and a thin groove is cut in the middle of the upper long wooden board, and three A small wooden strip is fixed with three square wooden blocks above the groove on the top surface. When the small wooden strip is moved horizontally, it can slide together with the square wooden blocks. This rai...

Abstract

The invention discloses a virtual experiment making method for a convex lens. The method is mainly comprises a video capturing flow, virtual-real fusion flow and an interactive display flow, and particularly comprises the following steps of: making a long wood board with a sliding guide rail, arranging three movable slide blocks on the long wood board, and placing three specified marks on the slide blocks respectively; and capturing the specified marks by using an ordinary camera, calculating the spatial locations and directions of the marks, mapping onto a virtual candle, a lens and an imaging board three-dimensional model respectively, synthesizing a virtual three-dimensional model which is generated in real time and a shot real scene to obtain a virtual-real fusion interactive scene, and displaying an object distance, an image distance and a focus distance in convex lens imaging in real time. The method is applied to middle school physical experiment teaching, and has the advantages of simple equipment, low cost, environmental friendliness and natural interactive behaviors; and a learner can adjust parameters at any time for observing the rule phenomenon of convex lens imaging, so that a good teaching effect is achieved.

Description

technical field [0001] The invention belongs to the field of physics teaching experiments, and specifically relates to a method for making a convex lens imaging virtual experiment. The method is a convex lens imaging experiment method based on virtual and real fusion of augmented reality technology, and is applied to middle school physics classroom teaching or student independent experiments. Background technique [0002] Augmented Reality (AR) technology and Virtual Reality (VR) technology appeared almost at the same time. As early as 1968, the first helmet-mounted display produced by graphics pioneer Sutherland was transmissive rather than fully immersive. Formally, it can be used as an AR device. In the following 20 years, due to the limitations of hardware equipment and graphics research itself, AR technology has not made significant progress. In the early 1990s, Boeing's Tom Caudell and his colleagues proposed the term "augmented reality" in the auxiliary wiring system...
