文中对速度追踪制导律和弹体追踪制导律的工作原理进行了研究，利用六自由度弹道仿真程序对弹道修正弹两种追踪方式下的末段修正弹道和脱靶量进行了对比计算，研究了两种追踪方式下激光探测器光轴的轨迹及激光探测器空间视场在地面投影区域的变化；弹体追踪方式命中精度虽然较低，但由于工程实现简单、成本低，仍有其工程使用价值。

In the process of contour tracing, contour lines are gained by tracing in anticlockwise order and a method of backdate search which ensures the correctness of the algorithm is used for contour tracing at those pixels where other contour pixels can not be continuously traced. By analysis of the neighbouring pixels, this paper avoids judging those pixels that no need to be compared again.

The experiment results will show the accuracy of the designed sun tracker under outdoor environment and then the MPP under two different sun tracking processes (uses sun tracker tracking or installs PV array toward the sun with 23.5 degrees immovably) also will be compared.

实验结果将会显示所设计的太阳追踪器在室外环境下能准确的追踪太阳位置。此外，太阳能板以固定朝南23.5和用太阳追踪器追踪到太阳后各自所产生的最大功值也将会被比较。

The distance between the reactive sensor node and the target node is estimated by using the value of RSSI, since the strength of radiation signal and the square of distance is inversely proportional. We proposed a method to derive the position of the target node based on the theory of radical center. With data from three reactive nodes, the position of target node can be analytically estimated.

我们以讯号强度指标来推估节点与被追踪物件的距离，并利用圆之根轴的几何特性，提出一个位置的估算方法，可以简单地利用三个感测节点所回传的资讯计算出被追踪物件的位置，所提出的方法即使在距离值有误差的情况下，依然能够估算出被追踪物件的唯一位置。

For getting the major characteristic edges without confusions by undesired structures like muscle edges, we integrate a star-like edge detection filter named "Asterisk Filter" with the Canny Edge Detection in the image preprocessing. In addition, we also propose a new contour tracking method named "One-Pixel Rolling Ball Contour Tracking" for getting the boundary information in a binary image which is a link-list data structure. Instead of using a regression curvature estimator, PCA is used for better curvature estimation from a discrete bony contour.

为了从影像上取得骨头特徵边缘，将不重要的肌肉视为杂讯滤除，我们引用一种星形滤波器－Asterisk Filter，搭配Canny边缘检测法，做为这类影像的前处理；另外，为了将骨头的边缘精确地追踪出来，我们提出滚球边界追踪法，来对二值化影像进行边缘追踪，藉此获得边缘的串列资料结构；我们采用以主成分分析(Principle Component Analysis，简称PCA)取代原本以回归方法来计算的曲率，以取得更佳的曲率估测值，其可提高计算之参数的准确性。
