空间座标

As to the remaining parameters, two methods are developed: first, accepting that the projection function complies with a circular function within at least a part of a given field of view, constrained by the obtained object-to-image radial mapping and a constant focal length, the best-fitting point of the optical origin is tested along the optical axis; secondly, referring to the postulation of the exclusively bilateral mapping between an imaged point and its scenic sight ray, a measuring technique is developed to survey the world coordinates which will fabricate a projecting path to the imaged points located on the imageable region of the image plane in order to directly model the projection geometries involved.

而针对其余参数本文提出两种解题方法：其一是根据『在「部分视野角范围」内，鱼眼相机的投射模型符合一典型的「圆形函数」』以标靶实体与其影像尺寸为限制条件，测试光学轴上的最佳视觉参考点、鉴定最适当的投射模型、焦距、及有效的视野角度范围。其二是根据『一视野线排他性地与对应「呈影点」一一映射』参考一呈影点来搜寻空间中对应视野线的绝对座标后，据以演绎相机内部影像形成的模型。

The interface also provides a spatial positioning method which helps designers to eliminate the commands of converting a coordinate axis.

并且提供一套空间定位的座标系统让设计者不需透过转换座标轴指令的步骤达成CAD环境中的空间操作。

Gamma-corrected RGB coordinates are referred to as R'G'B' space, and the luma value Y' is derived from these coordinates.

经过 Gamma 校正后的 RGB 坐标被称为 R'G'B 空间，其中亮度值 Y 可以从这些座标中提取出来。

In order to locate direct singular positions, we begin by expressing the determinant of the Jacobian matrix Jx in terms of position of the center P of the moving platform. The Z and the Y coordinates of P may be chosen from the workspace, then the determinant of Jx is now a six order polynomial of X, the x coordinate of P. The direct singular positions corresponding to are obtained by solving the polynomial equation, and retaining all real roots in the workspace.

由速度分析的Jacobian矩阵Jx，将其行列式值表示成活动平台中心点P位置的函数，寻找奇异位置的方法是先假设平台高度，再假设工作空间内P点的Y座标，使Jx行列式成为P点X座标的六次方程式，求解方程式并保留在工作空间内之实根。

One kind of such information is the geometry about an object in the space. The algorithm to extract such a kind of information usually includes an important procedure called "camera calibration." The purpose of camera calibration is to construct the relationship between the image plane of the camera and the coordinates system of the object space. The relationship is usually represented by a "mathematical function."

此类应用之演算法则中一般包含一重要之程序称为"摄影机校准"，其目的是在建立影像平面与物体空间座标系统间之对应关系，此对应关系以"数学函数"表示，并在校准后得到一组参数，用以代表此摄影机在物体空间座标系统中之"特性"表现。

Finally, spatial mapping system was applied to construct the map layer information, corresponding attribute information of spatial location, and multiple images database of spatial coordinates. These case studies were NTU campus, Da-An forest park , An-Kang farm of NTU in Taipei city, and experimental field for precision farming at TARI.

最后本研究以空间制图系统建构了图层资讯、空间定位中相对应的属性资料及具有地理座标的影像资料库，并以台大校园、大安森林公园与安康农场以及农业试验所精准农业试验场为研究场景。

Tool targeting process in this method only requires the image-to-patient registration, in which an automated laser surface scanner is used to unitize the spaces of patient and robot.

本方法的特性是利用自动雷射曲面扫描系统扫描病患脸部特徵及手术器械位置，之后再和医疗影像进行特徵点及曲面最佳化叠合，可直接将医疗影像的空间座标转移到机械手臂的座标架构。

Then, we construct a coordinate system for terminal bouton of PN in calyx of mushroom body.

然后在果蝇脑的蕈状体萼端定义一个座标系统，用以定位其轴突末梢的空间座标。

The error of a surface on the electrical potential distribution can be neglected when the order of the distance which from center to the surface we assume the potential decay to zero about 102 of its radius. This effect also can be neglected when the potential is high, but it can be taken into account by multiplying a correction function to the potential of surface when the surface potential is low.

并且当表面电位较高的时候，近似解析解对於空间电位的分布会有较好的描述，即和数值解的结果会有较少的误差；而在表面电位较低的情况下，圆柱座标以及球座标的近似解可以乘上一个校正函数来修正，则可以有效的大幅降低误差，更可以正确的描述胶体粒子内部的空间电位分布。

A Nubian Monarc C-4 hyperdrive increases the ship's range once astrogation coordinates are supplied by an R2 unit or similar. The compact hyperdrive is especially useful when N-1 fighters serve as the Queen's Honor Guard on visits to other planets.

藉由R2或类似装置提供导航座标，一具努比安Monarc C-4超空间引擎可延长此机的航程，这紧致的超空间引擎在N-1战机担任皇后前往其他星球的荣誉守卫时会特别有用。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
