How much should it cost? An introduction to management use of costing information

With the introduction of the internal marketthe health service is changing rapidly and health libraries must change with it. Many libraries arerequested to cost their services. The demand comes from external customers and from their ownorganizations. This paper discusses the various reasons for costing services and howcosting information can influence our management decision making. The paper challengeslibrarians to move costing processes away from a mechanistic approach, towards a means ofdemonstrating the worth of a library resources unit in cost and qualitative terms. Using costinginformation for cost control purposes, comparison of cost with other providers, setting prices ordetermining future service delivery levels is discussed, as well as considering the question ofexternal provision of library services. Use of information on fixed and variable costs andassessing break-even levels of service provision is illustrated as a helpful guide to library survival.     

三维影相的新算法——修正的直接线性变换

通过引入摄影机镜头的内、外方位元素的约束条件,导出了一种修正的DLT(MDLT)方法。该方法用于影片和录相的实测,得到一些有意义的结果。当测量的标定控制点点数较少(6～8个),且这些点的位置在空间和成像面分布不均匀时,用MDLT计算的结果比DLT的结果要好,误差可降低80％以上。
