3D 云查看器?
我有一个文件,其中包含一堆点及其 x、y、z 位置。我正在寻找一个简单的查看器,我可以在其中加载该点数据并查看它。旋转对于我检查云的深度至关重要正在生成。有人可以指出一个安装开销最小的轻量级查看器吗?
I have a file which contains a bunch of points with their x,y, z locations.I am looking for a simple viewer where in I can load this point data and view it .Rotation is essential for me to check the depth of the cloud being generated .Can someone point out a light weight viewer with minimum installation overhead for this?

我使用过MeshLab,它对我来说效果很好。 IIRC 它使用普通的 Windows 安装程序。
您还可以尝试 CyArk 查看器(Java 小程序),或 Leica Cyclone -- 我没有使用过其中任何一个。
当然,如果你的数据格式不是标准的,他们可能无法读取。
I have used MeshLab and it worked well for me. IIRC it uses your average Windows installer.
You could also try CyArk viewer (a Java applet), or Leica Cyclone -- I haven't used either one.
Of course if your data format is not a standard one, they may not be able to read it.
R+ 是一个开源统计程序,我就是为了这个目的而使用的。只需几行代码即可完成。
首先添加rgl和plotrix库。
输入以下代码:
其中 pcd 是文件类型(如果我没记错的话),前十行将被跳过,因为它们是标题 (
skip=10
) 和sep""< /code> 表示文件中使用的分隔符。最后一行代码绘制点并根据深度设置颜色。
R+ is an open source statistical program that I have used for this exact purpose. It can be accomplished in only a few lines of code.
First add the rgl and plotrix libraries.
Enter the following code:
Where pcd is the type of file (if I remember correctly), the first ten lines are skipped as they are a header (
skip=10
) andsep""
represents the delimiter used in the file. This last line of code plots the points and sets the color based upon depth.我投票给 Paraview。我很惊讶在我之前没有人提到过它。
无论您使用哪种操作系统,Windows、Mac OS 或 Linux,您都可以毫无(大)问题地使用它。 (你知道软件总是有错误)
Meshlab 也很好。事实上,如果你会学习Python,你可以轻松转换文件格式,以确保它们可以在不同的软件中使用。
我相信有人已经做到了。例如。 .off(Meshlab 格式)到 .vtk(Paraview 格式),就像这样 one。
更新1:
大多数可视化软件都是用户友好的,所以您遇到的问题可能主要是如何将您拥有的源数据转换为可以在这些查看器中使用的指定格式。如果有您拥有的数据示例,可能会有所帮助。
I vote for Paraview. I am shocked that no one mentioned it before I did.
No matter which OS you use, Windows, Mac OS or Linux you can use it without any (big) problems. (You know software always has bugs)
Meshlab is good too. In fact you can convert file format easily to make sure they can be used in different software, if you can learn Python.
I do believe someones has already done it. Eg. .off (Meshlab format) to .vtk(Paraview format), like this one.
Update1:
Most visualization softwares are user-friendly, so maybe the problem you have is mainly about how to convert the source data you have to the specified format which can be used in these viewers. It may be helpful if there is an example of data you have.
matlab 是一个非常好的可视化 pcl 工具,特别是用于进一步分析。
matlab is a quite good tool to visualize your pcl, expecially for further analysis.
