Point Cloud Library

The Point Cloud Library (PCL) is an open-source library of algorithms for point cloud processing tasks and 3D geometry processing, such as occur in three-dimensional computer vision. The library contains algorithms for feature estimation, surface reconstruction, registration, model fitting, and segmentation. It is written in C++ and released under the BSD license.

These algorithms have been used, for example, for perception in robotics to filter outliers from noisy data, stitch 3D point clouds together, segment relevant parts of a scene, extract keypoints and compute descriptors to recognize objects in the world based on their geometric appearance, and create surfaces from point clouds and visualize them.

History

The development of the Point Cloud Library started in March 2010 at Willow Garage. The project initially resided on a sub domain of Willow Garage then moved to a new website www.pointclouds.org in March 2011. PCL's first official release (Version 1.0) was released two months later in May 2011.

Pacific Coast Professional Football League

The Pacific Coast Professional Football League (PCPFL), also known as the Pacific Coast Football League (PCFL) and Pacific Coast League (PCL) was a professional American football league based in California. It operated from 1940 through 1948. One of the few minor American professional sports leagues that competed in the years of World War II, the PCPFL was regarded as a minor league of the highest level, particularly from 1940 to 1945, at a time in which the major National Football League did not extend further west than Chicago and Green Bay. It was also the first professional football league to have a team based in Hawaii (the Hawaiian Warriors).

Formed from the wreckage of a failed California Pro Football League, the PCPFL showcased the Los Angeles Bulldogs and the Hollywood Bears. The league became the “home” of African American football stars (including Kenny Washington, Woody Strode, and, briefly, Jackie Robinson) as the NFL had developed and enforced a color barrier in 1934 and extended until 1946.
