虚拟

Second, based on the screw theory, the'virtual joint'concept was proposed. By means of this concept, the conventional trajectory planning in Cartesian space was converted in the 'virtual joint'space, that is, the complex trajectory planning in Cartesian space was simplified by utilizing the trajectory planning in the'virtual joint'space.

第二、基于旋量理论提出了"虚拟关节"的概念，利用这一概念可以将传统的笛卡尔空间的轨迹规划转化成"虚拟关节"空间的轨迹规划，也就是说，利用简单的关节空间的轨迹规划方法实现了复杂的笛卡尔空间的轨迹规划。

The paper includes the constitutes of system hardware, image pretreatment, the achievement of parameter detection artithmetic. The main work is as follow: The pater makes use of vanguard genetic algorithms in image segmentation, uses vanguard genetic algorithms to get the image threshold. Using this method we may get different grey vehicles from the background exactly. Used the support vector machine theory to conduct the vehicles automatic sorting simulation research, the simulation result had proven this method could quite be accurate carries on the vehicles type the recognition; Improved based on the background automatic renewal hypothesized examination region algorithm, enhanced timeliness and the accuracy which the vehicles examines; And to has carried on the specify based on the hypothesized examination region imagery processing algorithm realization; In the paper also introduced withdraws the algorithm based on the gradation continuous movement vehicles characteristic to carry on the vehicles the characteristic to withdraw as well as to use the localization method which colored filter same gradation chart processing unifies to carry on the realization method which the vehicles license plate locates.
