查询词典 turning point

3D reconstruction is one of the most challenging problems in computer vision. This project uses CAD model to increase the accuracy,robustness and speed of 3D reconstruction and five different works are conducted: 1 research on space curve 3D reconstruction method based on high curvature point nad turning point; 2 free-form curve 3D reconstruction based on B-spline and BURBS; 3 Active surface affine reconstruction based on single frame; 4 Matching and reconstruction of 3D sparse points; Data fitting method based on the iteration of nearest point.

三维重建是计算机视觉中公认的难题，本项目使用CAD模型来提高三维重建的精度、稳健性和速度的思路，围绕着空间曲线和曲面的三维重建和匹配开展了以下五个方面的研究：1）基于高曲率点和拐点分割的空间曲线三维重建方法研究；2）基于B样条和NURBS表示的空间自由曲线三维重建方法研究；3）基于单帧图像的有源曲面仿射重建；4）三维离散数据的匹配与重建；5）基于迭代最近点的数据拟合方法。

He said that the business department with its customers to exchange the results showed that, although this year to bear a greater loss, but they are still actively seeking opportunities to rebound, with the result of the exchange fund clients showed that some Consensus has been formed, the current stock price adjustment should be able to fully reflect the risks (for example, a negative growth in 2009 profits) as long as there is no hard landing for the economy, a growing number of stocks have begun to show the value of the investment, on the other hand, the economy and earnings are still In a clear downward trend, investment strategy on economic policies still need to wait for the stock market and policy signals the emergence of two major turning point, the majority of investors in 2400 have not yet reflect the sharp point of the will of the holdings; However, if the market continued to fall, the brave will not hesitate On the left side of the transaction provide us with the risk.

他说，与客户业务部门交流的结果显示，虽然今年承受更大的损失，但他们仍在积极寻求与外汇基金的客户端显示的结果反弹的机会，一些共识已经形成，目前的股价调整应能充分反映风险（例如，在2009年利润负增长），只要没有经济方面，越来越多的股票已经开始硬着陆显示另一方面的投资价值，经济和收入仍处于明显的下降趋势，对经济政策的投资策略仍然需要等待股市和政策信号的两个重要转折点，出现了大多数投资者在2400年还没有反映的控股公司将尖，但是，如果市场继续下跌，勇敢不会在交易左侧毫不犹豫地提供了我们的风险。

The first rank derivative is a reflection of curve change and its rate, at certain range, if the sign of the first rank derivative has changed, the logging value of the correspondence depth point means maximum in this range; the second rank derivative is the knaggy property reflection of curve, at certain range, if the sign of the second rank derivative has changed, the correspondence depth point represent the inflexion of geophysical logging curve, it＇s also a turning point of the reflection of knaggy change property of the curve, it is the interface of stratum.

测井曲线的值是深度的函数，测井曲线的一阶导数表示了曲线变化的趋势和变化的快慢，在某一范围内，当一阶导数呈现符号转换时，相对应的深度点的测井值即为该范围内极大值；测井曲线的二阶导数则表示曲线的凹凸性，在某一范围内，当二阶导数呈现符号转换时，相对应的深度点代表了测井曲线的拐点，即反映曲线凹凸性变化的转折点，亦即地层的分界面。
