扫描线

The algorithm makes the discrete points sort in scan manner, and secondly it constructs convex hull and triangulates the sorted points by the optimal convex hull technology which is proved by the author, and optimizes triangles utilizing topological structures of directed edges.

该算法对离散点进行扫描线方式排序，利用最优凸壳技术进行凸壳的生成和三角网联结，最后利用有向边的拓扑结构进行三角网优化。

Scan line is used to detect the boundary of the horizontal rim, least square estimation is applied to compute its orientation, and elastic thread techniques is proposed to approach the curve with very low curvature.

提出了扫描线测量横向边框外沿并利用最小二乘法计算其走向的方法以及用来拟合曲率极小曲线的弹性线技术。

DSPR (Dynamic Scanlines Post-Reallocation) algorithm changes the boundary of block assigned to each Transputer after each operation, so that the total number of strips needed to travel around the network can be decreased, and then decrease the cost of communication.

DSPR后动态扫描线分配算法的出法点是运算后根据运算参数动态地改变分配给处理单元的显示区域的边界，这样就可以减少需要传送的不属于自己区域内的条码数量，进而减少运算后的通信开销。

Even worse are "line quadruplers" which are really deinterlacers combined with scalers that double the number of scan lines.

另一个更糟的用语就是&四倍密&，它其实是机器中「去交错」的功能配合上「扫描线 2X up-scaling」的功能罢了。

Use the mew accelerate function of OpenGL to accelerate the units display. Have adopted the three dimension graphics and OpenGL's technology, it makes use of Stencil test to carry on cutting operation, which reduces complexity of programming and has raised the speed and efficiency of displaying.

在后处理过程中，引进了DSI插值方法，改进了以往等值线插值，提高了算法速度和效率，满足了实时性要求，在扫描线算法的基础上，引进了OpenGL插值方法，改进了云图实现方法，提高了图形显示精度，在动画格式上，我们可以根据自己需要实现不同精度的不同压缩格式动画文件，提高了后处理显示应用场合，改变了以往动画格式单一的形式。

In addition, for the digitization of free surface object, the digitization strategy represents the powerful sampling capability of scanning line point cloud.

另外，对自由曲面的数字化展示了该数字化策略强大的扫描线点云采集能力。

At last, deal with N+1 subsection cloud data and scanning line.

然后拟合曲线，计算各点到曲线的距离，并删除距离超差的点，直到处理完n+1段点云，由此处理完所有扫描线。

Much noise exists in cloud data due to deviation of system and matching algorithm in photogrammetry. This paper presented an algorithm for scan line cloud data filtering.

摄影测量的点云数据通常叠加有多种形式的噪声信号，针对摄影测量中得到的扫描线形式的点云数据，采用形态学算子进行了噪声滤除。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
