摘要
从直接线性变换DLT的基本原理出发,分析了数码相机检校的DLT一般方法存在的缺陷,提出了附加约束条件的DLT相机检校方法的数学模型,并通过实验验证了其正确性和可行性。
It presents the weakness of DLT method used to calibrate non-metric digital camera from the basic principle of it. Based on this, a mathematical model for camera calibration with additional constrains conditions is provided, Experimental results demonstrate that this method is true and feasible.
