New AI method predicts roof geometry and segmentation from aerial images

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel method for simultaneously segmenting roof structures in aerial imagery and regressing their geometric attributes. This approach enhances Mask R-CNN with a specialized branch for attribute prediction, incorporating a conditional azimuth loss to mitigate noise in flat roof data and a log-normalized height representation to handle skewed building height distributions. The system, trained on a Dutch aerial image dataset derived from LiDAR data, achieved promising results with a mean absolute error of around 4 degrees for roof slope, 7 degrees for azimuth, and 1 meter for building height, alongside a strong instance segmentation performance.

    Joint Instance Segmentation and Geometric Attribute Regression for Roof Structures in Aerial Imagery

    arXiv:2605.26370v1 Announce Type: new Abstract: We present a method for jointly predicting instance-level roof segment masks together with three continuous geometric attributes -- building height, roof slope, and roof azimuth -- from a single aerial orthophoto. Our approach exten…
