Based on the three-dimensional binocular vision sensor measurement model, a kind of low cost single camera model used to measure coordinates in space was established.
以双目立体视觉传感器三维测量模型为基础，提出了一种用于测量空间三维点坐标的低成本单摄像机模型。
The paper derives a proximal formula of solution geodetic latitude from geodetic rectangular coordinates in space. It is simpler in form and more precision Than existing proximal formulas.
本文导出的由空间大地直角坐标直接解算大地纬度的近似公式，具有形式简单，计算精度高的优点。
So, in a way, you can think of these as a space analog of polar coordinates because you just use distance to the origin, and then you have to use angles to determine in which direction you're going.
也可以把这种坐标，看成是空间中的极坐标，它其实使用了，距离原点的距离，然后用角度这种标尺，来确定了方向。
