基于OpenMV视觉伺服的高精度电磁炮实验装置系统

The Experimental Device System of High-Precision Electromagnetic Gun Based on Open MV Visual Servoing

目前,大多数高校缺乏能够快速提升学生动手能力的实验装置,论文设计了一种可以直接用于电路电子教学的电磁炮实验装置。装置由以STM32单片机为核心的控制模块、充放电模块、电磁炮发射模块、OpenMV视觉模块及操作模块组成。为实现对电磁炮发射目标的精确控制,采用OpenMV视觉测距模块对目标区域进行检测,并反馈至核心控制模块控制双舵机云台调整发射角度,通过驱动充放电模块设定电磁炮的推进量进行发射。实践证明,基于OpenMV视觉伺服的高精度电磁炮实验装置系统能根据目标区域快速调整自身的发射角以命中目标区域。

At present,most colleges and universities lack the experimental device which can quickly improve students’hands-on ability.This paper designs an electromagnetic gun experimental device which can be directly used in circuit and electronic teaching.The device consists of a control module with STM32 single chip microcomputer as the core,a charging and discharging module,an electromagnetic gun launching module,an OpenMV vision module and an operating module.In order to realize the accurate control of the launching target of electromagnetic gun,the OpenMV visual ranging module is used to detect the target area,and feedback to the core control module to control the double steering gear pan tilt to adjust the launching angle,and the propulsion of the electromagnetic gun is set by driving the charging and discharging module to launch.Practice has proved that the experimental device system of high-precision electromagnetic gun based on OpenMV visual servoing can quickly adjust its launching angle according to the target area to hit the target area.
