Geometrical relationship among the length of triangle sides is used to determine the Angle of rotation, the cone can be machined without using measuring instrument.
利用圆锥三角形边长的几何关系来确定转动角度,可以不用测量仪器加工出圆锥体。
The results show that bright images used in gray scope can assure the measuring error scope within 5% of spray cone angle and the measuring error scope within 1% of penetration distance.
结果表明对于比较明亮且无阴影的图片仅应用灰度范围就能够保证喷雾锥角的测量误差在5%以内,贯穿距离的测量误差在1%以内;
