3D Point Cloud Registration Datasets and Benchmark Code


1. Datasets:

Our 3D point cloud datasets are modified format of 3D objects/shapse downloaded from KIT database ( available http://i61p109.ira.uka.de/ObjectModelsWebUI/). For each object,
different sizes point clouds are generated (100,200, 500, 1000, 2000) to evalute the efficiency of algorithms.

2. Benchmark Code:

In our experiments, we compare some popular 3D registration algorithms, e.g. ICP, Gaussian mixture, SoftAssign. We tested them under two circumstances:  first, with large motions
second, with large amount of outliers. Some examples are shown here:
