On the NCI chip, the phase, frequency, andintensity of the reflected light from different points on the object isdetected and used to determine the exact distance of the target point.
NCI测量并分析不同点的反射光，通过相位、频率和亮度三个参数来精准确定目标点与镜头的距离。
At the same time the feature point coordinates on the planar target were achieved with cross ratio invariability theory, then structured light parameters was calibrated.
同时利用交比不变性原理获取平面靶标上的特征点坐标，完成了结构光平面参数的标定。
