| 摘 要： | 在不同的构像畸变模型条件下,利用附加条件的DLT算法处理普通数码影像所得到的影像精度是不同的。控制点分布均匀时,进行试验,结果表明,在较少控制点情况下,可考虑引入3个畸变系数k1、P1、P2来提高解算精度;而当控制点数达到一定数量时,可考虑引入3个畸变系数k1、p1、p2或5个畸变系数k1、k2、k3、p1、p2以提高解算精度。

| Abstract: | The paper applies DLT adding condition equations to common digital photos for the different conformation distortion model.The results show that under less control point circumstance,3 mutation coefficients k1,p1,p2 should be considered to improve the solution calculate accuracy.But when the control point attains certain quantity,3 to 5 mutation coefficients k1,k2,k3,p1,p2 should be considered to improve the accuracy. |
