WebJul 26, 2024 · The pose and radius estimation process can be divided into three main steps: (1) the normal vector estimation of a cir- cular plane, (2) a 3D reconstruction of the circle center, and (3) the radius estimation using the center position. The overall procedure is shown in figure 1. The specific improvements of the proposed method are as follows. Webrtk - Recent models 3D CAD Model Collection GrabCAD Community Library.
