In February 2023, a vast balloon the height of a 22-storey building entered U.S. airspace, with a payload weighing 2,000 pounds and including solar panels and surveillance equipment.
To this end, a Rotation-invariant Convolution with Point Sorting and Curvature Radius (RCPC) is proposed. Firstly, to solve the challenge (i), a neighbor point sorting module (NPS) is introduced.
The researchers evaluated the manufacturing results by measuring key properties of the headlight lens, including light transmittance, surface profile, radius of curvature, diameter, height and surface ...
