Rapid urbanization poses social and environmental challenges. Addressing these issues effectively requires access to accurate and up-to-date 3D building models, obtained promptly and cost-effectively. Urban modeling is an interdisciplinary topic among computer vision, graphics, and photogrammetry. The demand for automated interpretation of scene geometry and semantics has surged due to various applications, including autonomous navigation, augmented reality, smart cities, and digital twins. As a result, substantial research effort has been dedicated to urban scene modeling within the computer vision and graphics communities, with a particular focus on photogrammetry, which has coped with urban modeling challenges for decades. This workshop is intended to bring researchers from these communities together. Through invited talks, spotlight presentations, a workshop challenge, and a poster session, it will increase interdisciplinary interaction and collaboration among photogrammetry, computer vision and graphics. We also solicit original contributions in the areas related to urban scene modeling.

As part of this workshop, we are hosting the S23DR challenge. What's next after Structure from Motion? The objective of this competition is to facilitate the development of methods for transforming posed images (sometimes also called "oriented images") / SfM outputs into a structured geometric representation (wire frame) from which semantically meaningful measurements can be extracted. In short: More Structured Structure from Motion.
In conjunction with the challenge, we release a new dataset: the HoHo Dataset. These data were gathered over the course of several years throughout the United States from a variety of smart phone and camera platforms. Each training sample/scene consists of a set of posed image features (segmentation, depth, etc.) and a sparse point cloud as input, and a sparse wire frame (3D embedded graph) with semantically tagged edges as the target. Additionally a mesh with semantically tagged faces is provided for each scene durning training. In order to preserve privacy, original images are not provided.
The winning submission will receive a cash prize provided by the workshop sponsor and the selected finalists will be invited to present their research in the workshop. In order to be eligible for the prizes teams must follow all the rules, provide a write-up detailing their solution in a submission to the workshop, in the form of an extended abstract (4 pages) or a full paper (8 pages), as well as all artifacts code, weights, etc., required to generate a winning submission under CC-BY4.0 license.
There is a $ 25,000 prize pool for this challenge.

As part of this workshop, we are hosting the Building3D challenge. Building3D is an urban-scale publicly available dataset consisting of more than 160 thousand buildings with corresponding point clouds, meshes, and wireframe models covering 16 cities in Estonia. For this challenge, approximately 36, 000 buildings from the city of Tallinn are used as the training and testing dataset. Among them , we selected 6000 relatively dense and structurally simple buildings as the Entry-level dataset. The wireframe model is composed of points and edges representing shape and outline of the object. We require algorithms to take the original point cloud as input and regress the wireframe model. For the evaluation, the metrics of mean precision and recall are employed to evaluate accuracy of both points and edges, and overall offset of the model is calculated. Additionally, the wireframe edit distance (WED) is used as an additional metric to evaluate the accuracy of generated wireframe models.
The winning submission will receive a cash prize provided by the workshop sponsor and the chosen finalists will be invited to present their research in the workshop. The prerequisite to receive a money prize is to provide a write-up detailing their solution by a submission to the workshop, in the form of an extended abstract (4 pages) or a full paper (8 pages), as well as the code required to generate a winning submission under CC BY4.0 license.

Iro Armeni is an assistant professor at the Department of Civil and Environmental Engineering, Stanford University, leading the Gradient Spaces group. She is interested in interdisciplinary research spanning Architecture, Civil Engineering, and Machine Perception. Her focus is on developing quantitative and data-driven methods that learn from real-world visual data to generate, predict, and simulate new or renewed built environments that place the human in the center. Her goal is to create sustainable, inclusive, and adaptive built environments that can support our current and future physical and digital needs.
