Methods An unsupervised local and global features extraction method was adopted for the localization of facial features of frontal view face image. First, a threshold was used to segment the image into foreground and background, and the nose was localized by considering the symmetry of the face. Second, Harris operator was adopted to detect interest points in a rectangular area covering all the facial features, and then local maximum of the interest points were detected. And finally, Kmeans clustering method was used to cluster the points and obtain the facial features localization.

针对红外正面脸部图像，采用一种无监督的局部和全局的特征提取方法，首先通过阈值法区分出前景和背景，并根据面部特征对称性在前景中确定鼻区；然后在面部确定一个包含所有特征的矩形区域，利用Harris算子在该区域检测出角点，并找出这些点的局部最大值点；最后用Kmeans方法对这些点进行聚类。

The outstanding of this study is: for system hardware design, a new voltage measuring circuit, which is used to measure the voltage of the individual battery of batteries is designed; for the functions of the new instrument, it is used to monitor the battery on-linely and real-timely not only when the battery is on floating charging but also on the course of charging and discharging with the new judging criterion of battery performance. Even more, the battery, which is good in floating charging and actually may be bad, could be found quickly by discharging for a short time periodically. The precision, automation and intelligence of the monitoring system for battery is improved greatly.

本论文工作的突出之处：在系统硬件设计方面采用了一种新的测量蓄电池组中单体电池电压的采样电路；在系统功能方面，不仅实现了对蓄电池浮充状态的实时在线检测，而且通过采用蓄电池组的均匀性判断标准实现了对蓄电池充、放电的动态过程中的性能状态实时在线检测诊断，还可以通过定期短时间放电的方法实现对蓄电池性能的快速判断，及时发现浮充状态时检测状况正常但实际己经存在故障的落后电池，极大的提高了对蓄电池检测的准确性、自动化和智能化程度。
