# README

본 장에서는 PCL에서 제공하는 기능들을 기반으로 3D 데이터 전처리, 필터링를 다루고 있습니다.

* Chapter 1 : 3D 데이터 읽고 저장하기 : PCD Read and Save 
* Chapter 2 : 작업 부하를 줄이기 위한 Downsampling : VoxelGrid filter
* Chapter 3 : 대상 영역 선정을 위한 RoI 설정 : PassThrough filter
* Chapter 4 : 센서 잡음 제거를 위한 Outlier제거 : Statistical/Conditional/Radius Outlier removal
* Chapter 5 : 바 세그멘테이션 및 제거 : RANSAC 

또한, 이해 돕기를 위해 각 챕터의 결과 확인에 맞는 PCD파일들을 사용하고 있습니다.
