Abstract: The 3D pose of a person may be estimated by triangulating 2D representations of body keypoints (e.g., joint locations) of the person. The triangulation may leverage various metrics such as confidence scores associated with the 2D representations of a keypoint and/or temporal consistency between multiple 3D representations of the keypoint. The 2D representations may be arranged into groups, a candidate 3D representation may be determined for each group, taking into account of the confidence score of each 2D representation in the group, and the candidate 3D representation that has the smallest error may be used to represent the keypoint. Other 3D representation(s) of the keypoint determined from images taken at different times may be used to refine the 3D representation of the keypoint.

Abstract: Disclosed in one embodiment of the present invention is an electroplating apparatus and an electroplating method. The electroplating apparatus comprises a plurality of paddles arranged in parallel. The paddles move in a direction parallel to a substrate, and are used to stir electroplating solution. Within one cycle, the paddles perform reciprocating motion at a set stroke, and the turning points of the reciprocating motion are related to the width of the paddles and the narrowest width of a gap between adjacent paddles. According to the present invention, by designing the size and movement mode of the paddles, the accumulated time in which each corresponding point on the substrate is blocked by the paddles is equal, so that the received quantity of electricity is equal, and thus the consistency of an electroplating height is further improved.
