Abstract The collection of fair-faced concrete appearance quality information is a prerequisite step for evaluation and also an important control step. It is affected by objective factors including collection equipment and environmental conditions. Based on the as cast finish concrete samples prepared in the laboratory and the as cast finish concrete components poured in the construction site, this paper studies the influence of UAV equipment parameters including sensitivity, shutter time, aperture value and camera size, UAV camera angle and the distance from the acquisition surface on the appearance quality information collection of as cast finish concrete. The appropriate range of each factor is given separately, and the corresponding collection method is adjusted considering the influence of the colored fair-faced concrete to minimize the deviation between the collected information and the real information.
