| Resumo | We present a segment-based approach to detecting damaged building roofs in aerial laser scanning data. It consists of a segmentation step, where points are grouped into planar segments, a feature extraction step, and a classification step, where each segment is classified as damaged or intact. Such a segment-based approach faces two major challenges: first, extraction of features that are relevant to the target classes and can adequately distinguish between the intact and damaged segments is not straightforward. Second, the generation of reference segments for training and testing is difficult due the complexity of interpreting point clouds. To overcome these challenges the role of feature selection and dimensionality reduction in training a classifier using few training samples is investigated. We evaluate the performance of several classifiers with different sets of features in terms of classification accuracy. The results indicate the usefulness of dimensionality reduction methods in segment-based classification of aerial laser scanning data with few training samples. With 12 features and 50 training segments a linear classifier outperforms more complex classifiers; however, dimensionality reduction methods result in larger improvements in the performance of complex classifiers. |
