1) confidence ellipse
置信椭圆
1.
It combines the resolution equations of passive time difference of arrival
location with actual movement of underwater target,uses the Extended Kalman
Filter(EKF) algorithm,analyses tracking problem of underwater target and the
confidence ellipse for every moment.
将被动时差定位的解算方程与水下目标的实际运动相结合,采用扩展卡尔曼滤波算法,分析水下目标的跟踪问题及其每一时刻的置信椭圆。
2) confidence ellipsoid
置信椭圆形
3) joint confidence ellipse
联合置信椭圆
4) ellipse bias
椭圆偏置
1.
In wire-cutting manufacturing of the top and bottom different
curve,accomplishing cutting way of ellipse bias changing curved surface which
between two plane curve into developable surface in order to calculate NC
program of four axis ganging.
在上下异型工件的线切割加工中,宜采用椭圆偏置切割法,即将上、下两平面曲线间的曲面变成可展直纹面,进而计算四轴联动的数控程序,可保障加工的效率与效益。
5) stable assessment
置信椭圆和位移向量
6) joint elliptical confidence region
联合椭圆置信区域
