In recent years, deep learning has been used to construct quantitative indicators relevant to urban areas. Given the diverse array of dense billboards in Taiwan, this study aims to utilize deep learning techniques, including semantic segmentation and object detection, in conjunction with street view imagery to quantify the spatial distribution of signboards. Moreover, this study examines the spatial distribution patterns within the research area. The results demonstrate that the MIoU value of Deeplab v3+ model achieves 83%, while the Precision and Recall of YOLOv7 model achieves 91.7% and 87.1%. The analysis of spatial distribution patterns results align well with the actual distribution of billboards. This study can serve as a foundation for further exploration and application of billboards, as well as for integration with other related fields.
