Therefore the authors put forward a calibration algorithm based on the grid image, which USES subdivision interpolation to approach the deformation and get a result of high-order interpolation.
Two-dimensional interpolation method is discussed to reduce the error of distance calibration which is caused by the omni-directional machining accuracy.
在距离标定中,本文提出的二维插值法减小了全景反射镜面因加工精度不高而带来的距离标定误差。

The calibration mode allows the image sensor generate calibration parameters which are used to improve the linearity of the sensor through a interpolation method.
