In order to improve the independence of the navigation information for unmanned aerial vehicle(UAV) landing,a novel monocular navigation method based on the calibration of corresponding lines is proposed,and it is used to determine the orientation and position relative to landing target for landing of UAV independently.
为提高无人机着陆阶段导航信息的自主性,研究了一种基于对应线标定的单目视觉位姿测量方法,以独立确定固定翼无人机在着陆时的姿态和相对着陆点的位置。
It has been found that there are more than one reaction pathway and more than one transition state determined by linear reaction coordinate between one reactant and one product.
研究中发现在反应物和产物的构型确定后,用线性反应坐标构造的反应途径和过渡态的构型不是唯一的。
A linear reaction coordinate R is used in the construction of the double - well potential for the intermoleculai' electron transfer from phenol anion radical to indole radical.
用AM1方法分别优化给体、受体和桥体的几何构型,用线性反应坐标构造了给体和受体分子间电子转移的双势阱,得到两透热势能面交叉处的反应坐标为R≈0。
