The"not escaped"pulsars of each group whose simulated projective places on to the Galactic plane lie in the range 0<r<25 kpc and 5<r<11 kpc from the Galactic center respectively are selected to make statistics on absolute height |z| distribution to derive the segmental scale height and the cumulative scale height.
对每组中"未逃逸"脉冲星,分别在0<r<25kpc和5<r<11 kpc两个区域中对|z|分布做了统计,研究了"未逃逸"脉冲星在这两个区域中的分段标高和累积标高的演化特征。

The system utilized four laser scanners along lengthwise direction of the log. Data are obtained in every ten degrees when log is turning, in each cross section, 36 data are obtained. Then the data obtained were processed and an outline of the cross section of the log was developed on computer screen. Afterwards, the largest inscribed circles for log cross sections were determined according to the principle that three points can determine a circle. Secondly, the points located on the cross sections were linked up along some log generative in order to simulate the three-dimension log outline. At last the largest right circular cylinder were optimized and the optimum turning center was determined by means of projective theory.
具体作法是:在木段长度方向均匀设置四个激光传感器,当木段旋转时,起动激光传感器,进行数据采集,每隔10~0扫描一个点,在各横断面圆周上共采集36个点的数据,由计算机处理采集的数据,并绘制出原木横断面的几何图形,再根据三点定圆的原理,确定出最大内接圆;其次,模拟原木三维廓形,即将原木相邻横断面上离散点沿着母线方向连线,由计算机分析处理,绘制原木三维廓形;最后,采用投影法,优化出原木最大内接圆柱体,并确定原木回转中心线。

As the contour of a wheel rim is easier to detect than the contour of a wheel, and the contour of a wheel rim and the contour of a wheel are approximately concentric circles on the same plane, we first detect the contour of the wheel rim, the center of the wheel rim and the contacting point between the wheel and the ground, then we detect the contour of the wheel via the invariance of cross ratio under projective transformation.
由于提取钢圈轮廓比提取车轮橡胶轮廓容易,而且钢圈轮廓和车轮轮廓可以近似看作同一平面上的两个同心圆,所以在本文中,我们首先提取钢圈轮廓、钢圈圆心和车轮与地面接触点在图像上的投影,然后利用射影变换保持交比不变的性质求出车轮轮廓。
