Next, we use the feature point's imagecoordinates, and their known world coordinates to calibrate camera.
接下来，我们利用以提取的特征点的图像坐标，以及它们已知的世界坐标进行摄像机标定。

In the end, equations of identified lines are obtained according to the imagecoordinates of points on the lines.
最后，根据图像中识别出的直线上各点的坐标，拟合出了直线方程。

As primary condition for visual measurement, camera calibration is focused on how to build the relation between imagecoordinates and spatial coordinates.
