物体的刚性运动(rigid motion)是指物体中的微粒持续运动,使得任意两个微粒之间的距离始终保持固定。刚体通过刚体运动从一个位置到另一个位置的净运动称为刚体位移(rigid displacement)。一般来说,刚体位移可能包括物体的平移和旋转。 给定一个物体,描述这个物体为空间R3 中的一个子集O⊂R3 。一个物体的刚性运动可用...
In this work a novel grid deformation algorithm, the finite transformation rigid motion mesh morpher (FT‐R3M) is proposed. FT‐R3M is essentially a mesh‐free grid deformation approach, since it does not require any inertial quantities and it gracefully propagates the movement of the bounda...
机器人操作的数学导论-第二章-刚体运动(Rigid Body Motion)(2) 3 空间R3中的刚性运动(Rigid Motion inR3) 回想一下第一节,刚性运动是保持点之间的距离和向量之间的角度的运动。我们通过使用刚体变换来描述刚体坐标系相对于惯性坐标系的瞬时位置和方向,从而表示刚性运动。这种表示依赖于这样一个事实,即刚体变换将右...
In this work, the Finite Transformation Rigid Motion Mesh Morpher (FT–R3M) is presented, an improved version of the Rigid Motion Mesh Morpher (Eleftheriou and Pierrot in Rigid motion mesh morpher: a novel approach for mesh deformation, 2016), that eliminates the need for sub-cycling, making...
A system and a method model the motion of a non-rigid object using a thin plate spline (TPS) transform. A first image of a video sequence is received, and a region of interest, referred to as a template, is chosen manually or automatically. A set of arbitrarily-chosen fixed reference ...

The aim of this article is to measure the motion pose of a rigid body in the B system relative to the W system, and the real-time spatial coordinate 𝑃𝑊PW of the center of mass P of the B-system rigid body in the W system. The imaging projection formulas are 𝑃𝑊=𝑇𝑊...
