2017年7月5日,百度举行了AI开发者大会,在会上发布了Apollo项目,并进行了演示,该项目在Github上已经能够被访问。出于一个程序员的好奇,昨天试玩了一把,确实不错。
http://apollo.auto/,这个是阿波罗的首页,感兴趣的可以注册成为开发者。https://github.com/ApolloAuto/apollo这个时候github的地址。装了个ubuntu,然后建一个目录。git clone https://github.com/ApolloAuto/apollo.git 克隆下来以后运行下面几个命令。
bash docker/scripts/install_docker.sh
bash docker/scripts/dev_start.sh
bash docker/scripts/dev_into.sh
第一个命令是安装docker,注意不要使用sudo,也不建议使用root账号。
第二个命令是开始部署开发环境,就是一堆的docker pull,这个时候需要等很久,如果你有一个好点的网络环境可能会快很多,我是运行了大半天。
运行好是下面的界面。

第三个命令是进入到docker容器中。
进到容器中了。
hackcat@in_dev_docker:/apollo$
至此,整个docker就搞完了,接下来就需要编译阿波罗了。
进入到容器后,运行以下命令进行编译。
bash apollo.sh build
漫长的等待啊,电脑性能要好点,我是等了一晚上,不知道几点搞好的,因为是虚拟机,分配的CPU内存都不多。至少40G硬盘吧。
编译好以后就可以在里面运行阿波罗了。
bash scripts/hmi.sh
打开人机交互界面。注意,不编译也能得到下面的结果,但网页打不开,看了下log是缺少各种文件。
hackcat@in_dev_docker:/apollo$ bash scripts/hmi.sh
Start roscore...
HMI ros node service running at localhost:
HMI running at http://localhost:8887
hackcat@in_dev_docker:/apollo$
用谷歌浏览器访问。 http://localhost:8887
打开以后是这样子的。左边的setup做两部操作,第一确定目前软件模块都已正确加载,即Debug列表中的模块,GPS驱动,控制器,总线,定位,Dreamview,数据记录等,第二步是确定GPS模块和CAN总线模块(这些是硬件模块)都已经安装,并能正常通信。然后就可以进行Record了,Record应该就是驾驶员驾驶车辆在封闭道路进行行驶,阿波罗记录数据。开始行驶的时候点击Start,行驶完了点击Stop。下面的Quick Play是执行刚才录制的轨迹,进行自动驾驶。有点像电脑上的屏幕录像脚本。
硬件相关信息百度也提供了文档,感兴趣的同学可以去购买一些来,据说三天就能打造出一辆自动驾驶汽车来。唯一苦恼的是,车辆需要有专业的总线技术服务公司来帮助我们进行对接,这个像我等屌丝去哪里找??

- The vehicle must be modified for “drive-by-wire” technology by a professional service company. Also, a CAN interface hookup must be provided in the trunk where the IPC will be mounted.
