Horizontal projectile motion virtual-real fusion experiment platform and method

Abstract

The invention discloses a horizontal projectile motion virtual-real fusion experiment platform which comprises a horizontal projectile motion instrument, a high-speed camera, a computer and a projector. The invention further discloses a horizontal projectile motion virtual-real fusion method. The method comprises the following steps: S1, enabling the high-speed camera continuously to shoot imagesof falling of a small ball; S2, identifying the images by the computer, and acquiring the position of the small ball in a high-speed camera image coordinate system at each moment; S3, converting the obtained central point position of the small ball in the high-speed camera image coordinate system into the position in the projector image coordinate system by the computer at each moment, and fittingpoints corresponding to each position in the projector image coordinate system into a curve; and S4, projecting the fitted curve to a horizontal projectile motion instrument by the projector, and carrying out virtual-real fusion presentation. On the basis of real experimental equipment and operation, an experiment is expanded on the basis of real experimental data, and virtual presentation is carried out.

Description

technical field [0001] The invention relates to the field of augmented reality technology, in particular to an experiment platform and method for combining virtual reality with flat throwing motion. Background technique [0002] Augmented reality (AR for short) is a technology that calculates the position angle of the camera image in real time and adds the corresponding image. The goal of this technology is to put the virtual world on the screen and interact with the real world. [0003] At present, the experimental teaching aids based on augmented reality technology on the market are still not widely used. Most of them achieve interactive functions by clicking on the mobile phone screen or using a computer mouse or keyboard, which has a weak sense of reality and poor interactive effects. Through the teaching resources of the invention to assist experimental teaching, students can use the interactive functions of real experimental instruments to complete experimental operati...

Problems solved by technology

[0005] The existing virtual experiment teaching technology has the following disadvantages: Most of the existing virtual experiments ignore the user's hand feeling in the actual operation, the experience is not strong, and it is not convenient for experimental teaching in primary and secondary schools

The disadvantage of the above scheme is that it ignores the user's hand feeling in actual operation, and the experience is not strong
