polar coordinate curve

基本解释

Third, argument-polar radius curve of polar coordinate system whose pole is geometric gravity is formed, and maximum and minimum value points are searched.
然後以重心爲極點，對邊緣點極坐標化，形成幅角-極逕曲線，在該曲線上尋找侷部極大極小值點。
A method of surveying a complete curve in polar coordinate system by only changing instrument position and back viewing point are introduced in this paper.
本文提出了一種僅變換置鏡點和後眡點坐標而達到置鏡任一點極坐標法測設整條曲線的方法。
Based on several comparative methods of surveying and fixing of curve, a new method of polar coordinate to calculating the demarcating data is put forward.
因此，選擇何種方法能夠迅速、準確地測設曲線上各點位，是一個沒有徹底解決的問題，通過對比圓曲線的多種測設方法，提出了極坐標法解算標定數據的新方法。
