摘要
传统的DLT算法是忽略畸变参数的一种相机标定方法,只能粗略地计算出内、外参数的初始值,不能用于之后的求解运算。本文对传统的DLT模型进行改进,改进后不需设定初始值,采取迭代线性化的数学算法,通过编写程序,在三维场地下实现了一种既快速又准确的新标定方法。并与TSAI算法进行对比实验,分析了本文改进的新算法在计算速度与求解精度方面的优势。
Traditional DLT algorithm is a kind of ignore the distortion parameters of camera calibration method, can only roughly cal- culate the initial value of the internal and external parameters, cant solve after operation. In this paper, the traditional DLT model im- provement does not need to set the initial value after improvement. Adopting iterative linearization mathematical algorithm, through the program, under the three dimensional space implements a new calibration method is rapid and accurate. And compared with TSAI al- gorithm to do the experiment, the paper analyzes the new algorithm of this paper to improve the calculation speed and precision of ad- vantage.
