AR-based mobile computer teaching instrument

Abstract

The invention provides an AR-based mobile computer teaching instrument. The instrument comprises a trough plate, a mounting base, a rotating rod and cylinders, wherein the mounting base is in clearance fit with the interior of the trough plate, the rotating rod is fixedly connected to the bottom end of the mounting base, the outer wall of the rotating rod is movably connected to the trough plate, the cylinders are fixedly connected to four corners of the lower surface of the trough plate, and a storage mechanism is mounted in the cylinder. Through cooperation of a baffle, a threaded pin, a nut, a spring, a connecting rod and a rolling wheel, the rolling wheel is separated from the ground when the connecting rod is stored in the cylinder, the phenomenon that the whole mechanism shakes in an operation process is prevented, through cooperation of a threaded rod, a bearing, a rotary disc, a prismatic cylinder and an ejection plate, students at different positions can observe conveniently, application and popularization are facilitated, by using a shell, bolts, a cover plate, a hinge pin and the like, when the teaching instrument is not used, the outer wall of the instrument may be covered with the shell, the cover plate seals the top of the shell, and the instrument is prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of computer teaching instruments, in particular to an AR-based mobile computer teaching instrument. Background technique [0002] Augmented reality, referred to as AR, is a technology that calculates the position and angle of the camera image in real time and adds the corresponding image. It is a new technology that "seamlessly" integrates real world information and virtual world information. The goal is to put the virtual world on the screen and interact with the real world. AR technology has applications in mobile computer teaching instruments. [0003] An AR-based mobile computer teaching instrument in the prior art, when in use, due to the small contact area between the rollers and the ground, the overall mechanism is prone to shaking, resulting in a decline in the practicability of the overall mechanism, which is inconvenient for students to observe and use Lack of protection together after the end, it...
