The Scene Understanding and Modeling Challenge


The SUMO challenge encourages the development of algorithms for complete understanding of 3D indoor scenes from 360° RGB-D panoramas with the goal of enabling social AR and VR research and experiences. The target 3D models of indoor scenes include all visible layout elements and objects complete with pose, semantic information, and texture. Algorithms submitted are evaluated at 3 levels of complexity corresponding to 3 tracks of the challenge: oriented 3D bounding boxes, oriented 3D voxel grids, and oriented 3D meshes.

Dataset

The SUMO challenge dataset is derived from processing scenes from the SUNCG dataset to produce 360° RGB-D images represented as cubemaps and corresponding 3D mesh models of all visible scene elements. The mesh models are further processed into a bounding box and voxel-based representation. The dataset format is described in detail in the SUMO white paper.

Participate


The SUMO Challenge is organized into three performance tracks based on the output representation of the scene. A scene is represented as a collection of elements, each of which models one object in the scene (e.g., a wall, the floor, or a chair). An element is represented in one of three increasingly descriptive representations: bounding box, voxel grid, or surface mesh. For each element in the scene, a submission contains the following outputs listed per track.

3D Bounding Box Track

3D Object Pose

Semantic Category of Element

3D Voxel Grid Track

3D Bounding Box

3D Object Pose

Metrics


Evaluation of a 3D scene focuses on 4 keys aspects: Geometry, Appearance, Semantic and Perceptual - (GASP) Details of the metrics for each track are provided here.
