| Summary: | This paper treats the technology to generate point clouds from photographs, more known as Dense Stereo Matching (DSM) or Structure from Motion (SfM), among other terminologies. The article presents the concepts, basic principles and architectural survey phases with DSM: planning, data acquisition, processing and post-processing to obtain other products from point cloud data. Then, we present several existing software for DSM, classified in three categories: web-based tools, free software/opensource and commercial software. Finally, we discuss the potentialities of this new technologies for architectural documentation and compare DSM with 3D laser scanning. |
