This paper analyses the essentiality of calibration, which is a process of determining the mapping function from measure space to theory space. 标定的实质是，由测量值空间到理论值空间的映射函数的确定过程。
This algorithm obtains the analytic texture mapping function which passes through the constraints by interpolating the constraints defined by the user with RBF. 该算法使用径向基函数插值用户给出的一系列约束点，从而得到满足约束条件的具有解析表达形式的纹理映射函数。
