This is point cloud of Chiang Kai-shek Memorial Hall (中正紀念堂) Point Cloud. It has 559219 points and loaded using PCL.

I was experimenting surface reconstruction on point cloud. I used Greedy Triangulation Projection implemented in PCL. Here’s the input point cloud (i used dataset from here http://svn.pointclouds.org/data/tosca_hires/) : The result was saved in .PLY file format and displayed using MeshLab (http://meshlab.sourceforge.net/) The result is not really good since the points are not dense enough. On [...]

This week i was trying to get 3D keypoints from Point Cloud. I use PCL and the algorithm is based on 2004 David G. Lowe paper. In PCL, the algorithm is extended 2D + 1 in the spatial domain. I was able to obtain the keypoint extraction through Difference of Gaussian. Currently i need to [...]

Hi, this article is about the very basic of PCL, how to install the dependencies, get PCL source code and build it :) The first step is download all dependencies at the web page below: http://pointclouds.org/downloads/windows.html On that page, OpenNI version is still 1.3, you can use the newer one, OpenNI 1.5.2. My system is [...]
