一、 KITTI数据集官方raw_data下载
KITTI是广泛用于自动驾驶领域评估的数据集之一，但是该数据集的数据很难下载。官方提供的下载方式是下载下图中的scripts，然后运行文件夹中的脚本，但是国内连接不上。科学上网只能在chrome浏览器上（网上教程很多哈），一个一个的去官网地址下载实在太麻烦了，因此写了一个脚本利用chrome浏览器下载raw_data。
数据集地址：https://www.cvlibs.***/datasets/kitti/
二、ubuntu下利用chrome下载的脚本
脚本如下，前面部分和官方提供的目录一致，主要是后面的部分修改如下所示，这个脚本在ubuntu系统下使用。
将该代码复制替换原本官方提供的raw_data_download.sh中的代码。
在该目录下打开终端，运行./raw_data_download.sh。
提醒一下，该代码中的File这里的目录要与chrome浏览器的下载目录一致，可以自行修改。
File='/home/liuyq/下载/'$shortname
果是windows的话，最下面的代码要修改一下。
#!/bin/bash

shortname=$i

下载过程：
三、Windows下的用chrome浏览器下载
用windows下载的话要改一下代码
这一句
x-www-browser 'https://s3.eu-central-1.amazonaws.***/avg-kitti/raw_data/'$fullname
修改为：
start chrome.exe 'https://s3.eu-central-1.amazonaws.***/avg-kitti/raw_data/'$fullname
四、解压脚本
解压的话创建脚本在下载的目录下，运行该脚本。
...
for i in ${files[@]}; do
if [ ${i:(-3)} != "zip" ]
then
shortname=$i'_sync.zip'
fullname=$i'/'$i'_sync.zip'
else
shortname=$i
fullname=$i
fi
echo "unziping: "$shortname
unzip -o $shortname
rm $shortname
done
