资源描述This paper presents a lowcost indoor location identification and material tracking methodology for construction projects using Ultra High Frequency (UHF) passive Radio Frequency Identification (RFID) technology. Onsite location aware information is an emerging area that focuses on automating delivery of spatial information pertinent to location of materials, workforce, and equipment. This spatial information can be used to derive knowledge about construction project status. A two-step algorithm is presented to automate the process of location estimation and material tracking in near-real-time. In this methodology, a number of passive RFID tags are distributed onsite where work is progressing, and a mobile RFID reader is carried by a worker onsite. Each passive RFID tag is deployed as a reference point with a known location (landmark) within a predefined zone. Reference tags of known locations are used to d

应用背景人脸识别，理解PCA的原理等~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~关键技术 通过 C 语言 和 opencv 来实现 PCA算法， 代码简单容易理解， 对于初学者 和想 通过代码来理解 PCA 的同学有帮助。 ·1——主成分分析 　　. 　　主成分分析 （ Principal Component Analysis ， PCA ）是一种掌握事物主要矛盾的统计分析方法，它可以从多元事物中解析出主要影响因素，揭示事物的本质，简化复杂的问题。

AffineTransform类描述了一种二维仿射变换的功能，它是一种二维坐标到二维坐标之间的线性变换，保持二维图形的“平直性”（译注：straightness，即变换后直线还是直线不会打弯，圆弧还是圆弧）和“平行性”（译注：parallelness，其实是指保二维图形间的相对位置关系不变，平行线还是平行线，相交直线的交角不变。大二学过的复变，“保形变换/保角变换”都还记得吧，数学就是王道啊！）。仿射变换可以通过一系列的原子变换的复合来实现，
