Abstract

Microscale environmental components, such as street furniture, sidewalks, and green spaces, significantly enhance street quality when properly identified and managed. Traditional in-person audits are time-consuming, so virtual audits using streetscape images and computer vision have been explored as alternatives. However, these often lack a comprehensive range of microscale components and do not consider attributes like materials. This paper proposes an automatic virtual audit method that recognizes microscale component types and materials in streetscape images using panoptic segmentation and material classification of segmented images of detected components. By surveying components affecting pedestrian-perceived street quality to include as many essential components as possible, 33 types of microscale components, as well as materials of sidewalk pavement, architectural elements, and street furniture, were identified with an overall F1 score of 0.946, demonstrating significantly improved performance compared with previous studies. This approach helps enhance street quality by evaluating built environments through an automatic virtual audit.

期刊介绍: Automation in Construction is an international journal that focuses on publishing original research papers related to the use of Information Technologies in various aspects of the construction industry. The journal covers topics such as design, engineering, construction technologies, and the maintenance and management of constructed facilities. The scope of Automation in Construction is extensive and covers all stages of the construction life cycle. This includes initial planning and design, construction of the facility, operation and maintenance, as well as the eventual dismantling and recycling of buildings and engineering structures.
