2021-f-drug_car's Introduction

2021-F-drug_car

一.介绍

2021电赛F题智能送药小车,比赛时间11/4日到11/7日,获得了全国一等奖。下面是开源的一些介绍及其他。

二.实现方案

1.OPENMV巡线

OPENMV巡线是我其中一个队友写的,具体思路是分区域找红色色块来寻中线和找边界转弯点,将数据传给stm32,openmv4大概25fps,plus大概45fps

2.K210数字识别

数字识别12345678文件夹里的所有内容可以移到一张sd卡里,给k210烧录启动固件(在官网maixpy有),就可以开机运行了里面的数据集已经是2500+的数据集,效果挺好的。

3.stm32核心主控

stm32f407负责控制电机和接收openmv,k210传感器数据并处理。核心找病房,回药房等算法实现都是再stm32主控实现。
关于主控stm32f407的代码,由于四天三夜时间限制,移植的是我之前的一个完全版工程,这次国电赛主要代码都要看keil里国电赛文件。代码很多也比较复杂,大家实在看不懂就算了,openmv和k210还是比较好理解的。

4.其他

最终版一号车是一号车的代码,主要看TASK2_GO这个函数,并且小车1永远都是执行任务2,默认是基础功能和扩展功能都发送数据,关于数据处理在二号车的中断处理代码那里。
小车二是专门用来走扩展功能的,扩展1走的是任务2,扩展2走的是任务3。
