Article summary:
1. Terrestrial laser scanning (TLS) and structure-from-motion photogrammetry (SfM) can both provide dense and accurate point clouds, which can be used to perform a morphological analysis of the façades of a masonry building.
2. A comparison between TLS and SfM performance in morphological analysis was conducted on two different buildings with different cross-sections.
3. The results show that TLS and SfM have similar performance in morphological analysis under optimal conditions.
Article analysis:
The article is generally reliable and trustworthy, as it provides evidence for its claims through the comparison of TLS and SfM performance in morphological analysis on two different buildings with different cross-sections. The authors also provide useful operational hints for a successful survey and effective data processing, which further adds to the trustworthiness of the article.
However, there are some potential biases that should be noted. For example, the authors do not explore any counterarguments or present both sides equally when discussing the advantages of using either TLS or SfM for morphological analysis. Additionally, they do not mention any possible risks associated with using either technique, such as cost or time constraints. Furthermore, there is no discussion about other techniques that could be used for morphological analysis, such as digital photogrammetry or thermal imaging.
In conclusion, while this article is generally reliable and trustworthy due to its evidence-based claims, there are some potential biases that should be noted when considering its content.
