Abstract: Systems and techniques are provided for part segmentation. For example, a process for performing part segmentation can include obtaining a three-dimensional capture of an object. The method can include generating one or more two-dimensional images of the object from the three-dimensional capture of the object. The method can further include processing the one or more two-dimensional images of the object to generate at least one two-dimensional bounding box associated with a part of the object. The method can include performing three-dimensional part segmentation of the part of the object based on a three-dimensional point cloud generated from the one or more two-dimensional images of the object and the at least one two-dimensional bounding box and based on semantically labeled super points which are merged into subgroups associated with the part of the object.

Abstract: An ultra-thin narrow-bezel panel light includes a base plate and a bezel surrounding the base plate. The base plate includes a plurality of side walls and an accommodating portion between the side walls, and the height of the base plate is 18 mm˜26 mm. Each of the side walls has a connecting side and the side walls are installed and fixed on the bezel via the connecting sides thereof, such that the overall height of the panel light can be reduced to 20 mm˜28 mm. Thus, the panel light can be ultra-thin, low-cost and of narrow bezel.

Abstract: A lighting device having prism grating microstructure includes a light tube body and a light source board. The light tube body includes an installation base and a light cover connected to each other to form an accommodating space. The light cover includes a first microstructure portion, a second microstructure portion and a light concentrating portion. The first microstructure portion and the second microstructure portion are disposed at the two sides of the light concentrating portion respectively, so the first microstructure portion and the second microstructure portion are connected to each other via the light concentrating portion. The light source board is disposed on the installation base and in the accommodating space. The first microstructure portion has a plurality of first prism steps orderly arranged and the second microstructure portion has a plurality of second prism steps orderly arranged. The first microstructure portion is symmetric to the second microstructure portion.
