 The development of roughness measurement techniques has evolved significantly since the 1960s. Laser inertial profilers have become the most common method used in the industry, while three-dimensional triangulation is increasingly used in automated systems. Research into roughness measurement has grown exponentially in recent years, with crowdsourcing, UAVs, and SAR imagery being used more frequently. Despite this, the use of 3D systems is likely to remain dominant in the industry. This article was authored by Ollie Fares and Tarek Zayed.
