Semi - parametric fitting of the track of perspective center and attitude of airborne tls ccd system 摄影中心轨迹及姿态拟合的半参数法
Work is done to find out the relationship between scroll wraps profile and the track of machining tool . a general equation about the relationship is recommended 摘要对涡旋型线加工的刀具中心轨迹程序进行了分析,提出了通用刀具中心轨迹方程并简单介绍了其应用情况。
Based on the data processing it can determine the radius of laser beam , and automatically calculate the orbits of the sintering center according to the boundary of the parts , and the precision of parts is made better 对加工参数选择进行研究,确定光斑半径补偿,并根据轮廓直线的转接情况自动计算出烧结中心轨迹,得到了精度较高的原型坯件。
The other used a similar locomotor orderliness to substitute the original by compare . the new academic and actual contour curve of the cam and tracks of polar and right angle coordinates of the center of reamer were presented , too 第二种是通过与原开牙凸轮机构从动件运动规律相比较,采用一种相似的运动规律来替代原运动规律,也给出了凸轮理论轮廓曲线、实际轮廓曲线和刀具中心轨迹。
To adapt the width of welding lines and improve the welding quality , adding swing to the moving on theoretical center track is put forward with the actual welding process synthetically thought of . circle swing mode and . sine swing mode are discussed as typical ones and the equations of moving tracks are established 为了适应焊缝的宽度,提高焊缝的质量,并结合焊接过程的实际情况,确定了在理论中心轨迹的基础上添加附加摆动,讨论了圆摆动和正弦摆动两种典型模式,建立了运动轨迹的方程。
