已知点 meaning in English
given point
known point
Examples
- In this distance , the unknown bore is forecasted by choosing known bores
通过在此相关距离内选择已知点，对未知点进行预测，得到预测结果。 - Z coordinate and direction angle of the instrument can be calculated and reset by measuring z coordinate of known points ( max . 10 points ) displayed
通过观测已知点的高程（最多10个点）来计算并重新设置测站点的高程与方位角。 - Resection is used to determine the coordinates of an instrument station by performing multiple measurements of points whose coordinate values are known
后方交会是利用在未知点上对若干已知点进行观测，获得的观测值来计算出未知点的坐标。 - Create a new coordinate by measuring to two points . the 1st point becomes the origin and the 2nd point becomes the n axis direction
通过观测两已知点即可确定一新点的坐标。坐标系为：第一个点作为坐标原点，而第一点到第二点的方向作为n （轴）方向。 - With the color and luminance difference of wheat field and outside the field , the position of field edge and the candidate points of it could be detected ; the slope of the field - edge was calculated by using passing a known point hough transform
