In: Proceedings of the IEEE Conference on computer vision and pattern recognition, pp. Experiments showed that our method could achieve satisfactory results on the publicly available point cloud datasets in both tasks of segmentation and 6D pose estimation.Īrmeni I, Sener O, Zamir AR, Jiang H, Brilakis I, Fischer M, Savarese S (2016) 3d semantic parsing of large-scale indoor spaces. Specifically, 3D features are extracted via a CNN-based architecture where the input is XYZ map converted from the initial point cloud. To acquire good estimate, we propose a new 6D pose estimation approach that incorporates both 2D and 3D features generated from RGB images and point clouds, respectively. Once the objects are segmented, the range of point clouds for each object in the entire scene could be specified, which enables us to further estimate the 6D pose for each object within local region of interest. Our PointDoN is flexible to be applied to any convolutional networks and shows improvements in the popular tasks of point cloud classification and semantic segmentation. In order to accurately segment foreground objects, a novel shape pattern aggregation module called PointDoN is proposed, which could learn meaningful deep geometric representations from both Difference of Normals (DoN) and the initial spatial coordinates of point cloud. In this paper, a unified deep learning framework for 3D scene segmentation and 6D object pose estimation is proposed. However, recognizing objects as well as the poses from point clouds is still a great challenge due to the property of disordered 3D data arrangement. create nets for regular and semi-regular polyhedra using knowledge of the faces and symmetry.Point cloud is currently the most typical representation in describing the 3D world.anticipate if an arrangement of regular polygons around a vertex will create a bounded polyhedron.anticipate the features of the solid created when a Platonic solid is truncated.use the terms faces, edges and vertices to describe models of polyhedral and look for relationships between these features.construct models of polyhedra using construction materials, like geoshapes or polydrons.use rulers, compasses and protractors accurately.investigate the relationship between the angle of the diagonal and length of rectangles sides.investigate the relationship between the diagonals and lengths of a rectangle.create designs which have reflection symmetry, rotational symmetry (orders 2, 3, 4, 6) and translational symmetry.identify the order of rotational symmetry of a given shape (how many times it "maps" onto itself in a full turn).find all the lines of reflection symmetry in a given shape.identify 3-dimensional shapes in the environmentĢD to 3D: Working with shapes and representations.classify 3-dimensional shapes by their properties.create nets that fold to form solid objects.use both English and Te Reo Māori to describe different polygonal shapes.investigate properties of symmetry in shapes.use the terms faces, edges and vertices to describe models of polyhedra.construct models of polyhedra using everyday materials.describe the differences between common two-dimensional mathematical shapes in relation to number of sides. name common two-dimensional mathematical shapes.describe the process of making shapes with line symmetry.explain in their own language what line symmetry is.make, name and describe polygons and other plane shapes.explore and describe faces, edges, and corners of 2D and 3D objects.name 2-dimensional shapes: triangle, square, oblong (non-square rectangle), circle, oval, pentagon, hexagon and diamond.explore, experiment and talk about the form and function of the shapes in their own language.discuss differences and likenesses of the shapes.classify 2D shapes according to how many sides they have.use the language ‘side’ and ‘corner’ in describing shapes.describe shape attributes in their own language.sort, compare and classify 2D and 3D objects such as triangle, square, oblong, circle, oval, pentagon, hexagon, diamond, box, cylinder, and sphere.
