MFTSC: A Semantically Constrained Method for Urban Building Height Estimation Using Multiple Source Images

Yuhan Chen,
Qingyun Yan,
Weimin Huang

Abstract: The use of remote sensing imagery has significantly enhanced the efficiency of building extraction; however, the precise estimation of building height remains a formidable challenge. In light of ongoing advancements in computer vision, numerous techniques leveraging convolutional neural networks and Transformers have been applied to remote sensing imagery, yielding promising outcomes. Nevertheless, most existing approaches directly estimate height without considering the intrinsic relationship between semantic… Show more

“…Compared with other sensors, such as LiDAR [8], the acquisition cost of remote sensing images is obviously lower. Therefore, estimating building heights from remote sensing images has become a credible idea [9]. However, since a single image may correspond to countless height structures, estimating the height of buildings from a single remote sensing image is a challenging problem.…”

“…In urban areas with both optical images and SAR images, improving the precision of building height estimation by fusing optical images and SAR images has begun to attract attention. Although there have been some studies [9,12] aiming to fuse SAR images and optical images to estimate building heights, these methods ignore the exploration of fusion methods adopting SAR images and optical images, which simply combine the features of the two modalities. This simple combination of heterogeneous features often leads to a decline in results and fails to achieve the purpose of complementing the feature information of the two modalities.…”
