Image processing can be valuable in many aspects of the construction sector, including progress monitoring, material classification, resource tracking, and recognition. Massive images and videos are captured on construction sites regularly due to the growth of capturing devices, the accessibility of the Internet, and the increasing volume of storage databases, which has encouraged scholars to visually capture the different aspects and actual state of construction sites using image processing. Many researchers have conducted valuable attempts and developed a wide range of complicated methodologies for construction monitoring. Few studies, however, completely describe existing methodologies and introduce the challenges and opportunities for the implementation of image processing in the construction industry. As a result, this study focuses on the general technological path of many applied image processing techniques and tools employed in the construction sector to help researchers select research methodologies and approaches. This is followed by a discussion of potential research directions. © 2024, Institute of Technology PETRONAS Sdn Bhd.
