Abstract: An approach is provided for detecting objects and associated pose from imagery data. The approach, for instance, involves processing an image using a feature representation network to generate a set of points representing the object detected in the image. Each point, for instance, has an attribute indicating a geometric part of the object. The approach also involves using the feature representation network to construct a bounding box around the set of points. The approach further involves determining a pose of the object based on the bounding box and the attribute indicating the geometric part of the object for each point. The approach further involves providing the object, the pose, or a combination thereof as an output.

Abstract: An approach is provided for lane-level direction-of-travel detection from overhead imagery. The approach, for instance, involves processing overhead imagery data of a road network to determine a plurality of features indicative of a direction of travel of at least one road lane of the road network. Each feature of the plurality of features indicates a candidate direction of travel. The approach also involves determining the direction of travel of the at least one road lane based on a weighted voting mechanism applied based on the candidate direction of travel of each feature. The weighted voting mechanism weighs the candidate direction of travel of each feature based on a feature type of each feature. The approach further involves associating the determined direction of travel as an attribute of the at least one road lane in a geographic database.

Abstract: This application provides a display apparatus and an electronic device. A transparent dielectric layer is added to the display apparatus, metal is deposited on the transparent dielectric layer, to form a metal grid, and a part of the metal grid is used as a radiator of an antenna structure. After an antenna is integrated into the display apparatus, through optimization of an optical design, the metal grid may meet a requirement for optical transmittance, and display effect is not obviously affected. In addition, because the antenna structure is integrated into the display apparatus, coverage space of a wireless signal is increased. This avoids occurrence of a signal blind region, so that the electronic device has a more reliable connection in a millimeter-wave band, to meet a communication requirement.
