“…A detailed discussion on its potential use for crowdsourcing applications in climate and atmospheric sciences is provided in Muller et al (2015). The combination of the RPi with the PiCamera module is very popular in home security applications (Prasad et al, 2014 andNguyen at al., 2015), in creating depth estimation systems (Zhuang, 2016) in particular for UAV usage (Neves at al., 2013 andCooper et al, 2017), in traffic monitoring (Kochláň et al, 2014), in agriculture (Jindarat et al, 2015), and also in environmental sciences (Ferdoush et al, 2014). The new photogrammetric system presented in this paper is intended for civil and mining engineering applications, in particular for monitoring rock cuttings along major roads and railway networks and high vertical rock surfaces within mining operations.…”
