For each match point, the position, scale factor and the rotation angle of the object in scene image can be computed, so the 4d vote space is formed.

对每个可能的匹配对，计算场景中模板图像的位置、尺度变化因子和旋转角度，构成一个4维的投票密度图，则密度最大的地方就是最后的定位结果。

And the effect of the image distortion center bias and scale factor ratio offset on image correction quality is discussed.

并对图像的畸变中心和纵横比例因子对校正的影响做了探讨。
