3DLineDetection

A simple and efficient 3D line detection algorithm for large scale unorganized point cloud. A conference paper based on this code has been submittd to ICPR2018.

Prerequisites:

1. OpenCV > 2.4.x
2. OpenMP
3. No other libs

Usage:

1. build the project with Cmake
2. run the code
3. The default parameters are useful for general cases without tunning(at least for these cases in the experiences of the paper). However, you can also adjust the parameters if the result is not very good.

Performance:

On a computer with Intel Core i5-3550p CPU, the computing time for point clouds with 30M, 20M, 10M, 5M, 2M and 1M points is 130s, 80s, 40s, 20s, 8s and 4s, respectively.
