Then, the geometric projection method was used to measure the characteristic parameters of the images.

其次，针对激波图像的特点，采用坐标投影法给出了图像测量的算法和步骤。

This paper presents a multiple stages calibration method of CCD array camera, which separate the interior parameters and exterior parameters based on the principle of geometric projection.

提出了一种CCD阵列相机几何标定的多级处理方法。 根据几何成像原理，该方法把相机内外部参数分开求解；
