In this paper, a method is presented for estimating 3-D motion parameters of a rigid body. This method has following features: 1. It is a linear method in which the interactive solving is not needed. 2. The equations for motion estimation contain only five unknowns-the number of the recoverable motion parameters. The time cost of motion estimation is largely reduced. 3. The Least-Square method is used so that the algorithm can be applied to the image sequence with noise, recovering the shape of visible surface...

本文提出了一种由光流估计刚体的三维运动参数的方法。该方法具有以下几个特点;1.该方法是线性的,不需迭代求解;2.建立的运动估计方程所用的未知数个数降至五个——刚好是可恢复的运动参数个数,大大缩短运动估计所用的时间;3.引入最小二乘法使算法对噪声具有平滑作用。最后讨论由运动参数恢复可见表面形状的可能性。

Under the condition of different thickness plate such as a flat plate with stepped discontinuity, the effects of shear, mass moment of inertia and in-plane wave generation on the power flow in the structures must be accounted. Based on the principles of power flow analysis and structural dynamics, a model on power flow for assemblies of beam-flat plate with stepped discontinuity is set up in this paper. The calculation results from the power now model are well conformed with the results measured by the method...

当板的厚度较大和变化时,如厚板或阶梯类的板,这时板的剪切、转动惯量及板的面内运动,将对板结构的振动功率流产生影响。基于功率流的分析方法和梁、板动力学的原理,推导了梁一阶梯板耦合结构的功率流表达式。计算和测量结果表明:振动频率较低时,板厚比增大使得从梁传递到阶梯板的功率流减小;振动频率较高时,梁-阶梯板结构的传递功率流小于梁-薄板结构的传递功率流。在这类板结构功率流估计中应注意这些差异,否则将引起功率流估计的误差。

和传统的高斯聚焦声束相比,有限衍射声束具有较大的声场深度,可以用于医学成像、组织定征、材料的无损检测、多普勒血流检测等许多领域。理论上非衍射声束只能由无限大孔径换能器产生,实际应用中,用有限孔径近似产生的有限衍射声束也具有很大的声场深度。本文介绍了有限衍射声束的产生、各方面特性、及在医学成像、血流估计方面的应用。
