查询词典 centerline

A "Masthead light" means a white light placed over the fore and aft centerline of the vessel showing an unbroken light over an arc of the horizon of 225 degrees and so fixed as to show the light from right ahead to 22.5 degrees abaft the beam on either side of the vessel.

In order to perform an accurate navigation, the centerline of the model must be extracted. In this paper, a new centerline extraction algorithm based on Hessian Matrix is proposed.

要想快速准确地进行虚拟内窥漫游，一个首要的步骤是要先提取出模型的中心线以指导视点的移动。

This approach uses the geometric features and radiation features of the road, according to the small amount seed points given by the user, each point in the road centerline can be gotten. Then an adaptive gray template is used to adjust each point in the road centerline. Finally, least square method and Newton iteration method are adapted to each point in the road centerline to fit a polygonal line.

该方法利用道路地物的几何特征和辐射特征，根据用户提供的少量道路种子点，利用自适应灰度模板对道路中心线上的每个点进行调整，最后采用最小二乘算法和牛顿迭代法对调整后的道路中心线上的每个点进行拟合，以此获得趋近于道路中心线的最佳折线。

The centerline of the chain is not at a uniform radius, as is the centerline of a belt passing around a pulley.

链条的中心线并不像绕过滑轮的皮带的中心那样是处于均匀的半径上。

The formation of billet steel rocker was calculated theoretically and analyzed using the differential method of rolling pressure along width in rolling deformation zone according to the position of the billet steel skid mark,the asymmetrical distribution of the mark degree and the departure of rolled piece centerline from the centerline of rolling.

在轧制变形区应用轧制压力宽向微分法，从钢坯滑道黑印位置和黑印程度的非对称分布、轧件中心线偏离轧制中心线两方面对钢板镰刀弯的形成进行了理论计算和分析，提出了改进操作规程、提高推床适应能力、改进加热炉滑道、加强加热工艺技术管理以及实施热送热装提高热坯的供应能力等多项措施，以适应多倍尺轧制工艺的要求。

The results demonstrate that mixing bubble to pure jets makes the profile of water elevation flatting, the velocity distribution of centerline rising and the fluctuation of velocity near surface fluctuating. The fluctuation of the centerline velocity lack of self-preserve and the whole flow field represents the characteristics of anisotropies.

对比纯射流情况，掺气射流中掺气使得射流中线附近的流速增大；对流场紊动量的分析表明，掺气使射流中心处水面的紊动加剧，掺气射流的紊动强度在射流的中垂线上不具有自相似性，射流在流场中表现为各向异性。

It respectively constructs quasi projection-separation facet sets of two convex polytopes while their orthogonal projection on the centerline overlap mutually. Afterward it judges the separation of two convex polytopes by confirming non-overlap in orthographic projection on the centerline or by finding out a projection-separation facet from two quasi projection-separation facet sets, otherwise a collision is judged.

该算法通过判断2个凸多面体在中心线上的正投影不相交，或者分别构造它们的准投影分离面集合，并从这2个集合中找到一个投影分离面，来判断2个凸多面体分离；否则，判断为相交。
