Matterport3D场景ID标注

2022-01-08 Views 研究556字3 min read繁

Matterport3D论文里虽然给出了所有场景的俯视图，但没有给对应ID。为了做可视化手动标注了部分场景ID。

场景俯视图

在Matterport3D: Learning from RGB-D Data in Indoor Environments中下载LaTeX格式的论文可以拿到俯视图的高清PDF文件

ID标注

标注工作使用了habitat-sim自带的habitat-viewer工具。该工具可以3D视角查看某个具体的场景。
前置条件

安装habitat-sim
获取mp3d数据集。可从Matterport3D申请下载脚本download_mp.py，并按如下方式下载压缩包：

python download_mp.py --task habitat -o ./

下载完成后解压，保证目录结构为data/scene_datasets/mp3d/{scene}/{scene}.glb

接下来开始枚举大法。新建view_all.sh脚本并放置在data/下，内容为

for i in "5ZKStnWn8Zo" "zsNo4HB9uLZ" "kEZ7cmS4wCh" "YmJkqBEsHnH" "D7G3Y4RVNrH" "ur6pFq6Qu1A" "uNb9QFRL6hY" "S9hNv5qa7GM" "2n8kARJN3HM" "ULsKaCPVFJR" "RPmz2sHmrrY" "8194nk5LbLH" "29hnd4uzFmX" "759xd9YjKW5" "sT4fr6TAbpF" "1LXtFkjw3qL" "Uxmj2M2itWa" "EDJbREhghzL" "ARNzJeq3xxb" "ZMojNkEp431" "Vvot9Ly1tCj" "EU6Fwq7SyZv" "yqstnuAEVhm" "s8pcmisQ38h" "PuKPg4mmafe" "PX4nDJXEHrG" "JF19kD82Mey" "JeFG25nYj2p" "dhjEzFoUFzH" "i5noydFURQK" "ac26ZMwG7aT" "VVfe2KiqLaN" "rPc6DW4iMge" "oLBMNvg9in8" "2t7WUuJeko7" "p5wJjkQkbXX" "pRbA3pwrgk9" "sKLMLpTHeUy" "X7HyMhZNoso" "TbHJrupSAjP" "B6ByNegPMKs" "r1Q1Z4BcV1o" "SN83YJsR3w2" "q9vSo1VnCiC" "VzqfbhrpDEA" "Pm6F8kyY3z2" "HxpKQynjfin" "qoiz87JEwZ2" "Z6MFQCViBuw" "cV4RVeZvu5T" "jtcxE69GiFV" "82sE5b5pLXE" "mJXqzFtmKg4" "gZ6f7yhEvPG" "5LpN3gDmAk7" "VFuaQ6m2Qom" "gTV8FGcVJC9" "17DRP5sb8fy" "YFuZgdQ5vWj" "jh4fc5c5qoQ" "r47D5H71a5s" "E9uDoFAP3SH" "QUCTc6BB5sX" "e9zR4mvMWw7" "vyrNrziPKCB" "x8F5xyUWy9e" "5q7pvUzZiYa" "pa4otMbVnkk" "V2XKFyX4ASd" "8WUmhLawc2A" "YVUC4YcDtcY" "wc2JMjhGNzB" "7y3sRwLe3Va" "aayBHfsNo7d" "D7N2EKCX4Sj" "Vt2qJdWjCF2" "b8cTxDM8gDG" "pLe4wQe7qrG" "gYvKGZ5eRqb" "gxdoqLR6rwA" "fzynW3qQPVF" "2azQ1b91cZZ" "JmbYfDe2QKZ" "GdvgFV5R1Z5" "rqfALeAoiTq" "VLzqgDo317F" "WYY7iVyf5p8" "UwV83HsGsw3" "XcA2TqTSSAj" "1pXnuDYAj8r"
do
    habitat-viewer --orthographic scene_datasets/mp3d/$i/$i.glb
done

该脚本运行后会依次以全局视角打开每个场景，这样就能手动和俯视图对应上了
