目标定位系统中图像失真的自动校正

Automatic image correction in target location system

文章讨论了目标定位系统中失真图像自动校正的方法,并保证目标定位的精确性。在球面投影模型的基础上,以保持直线特性为约束,实现了广角镜头图像的自动校正。建立几何校正模型,采用分块迭代校正的方法,消除了不确定性误差的影响,可将失真图像中的目标精确定位到真实场景中。

An automatic image correction method for target location system is discussed in this paper. Based on spherical projection model, con- sidering the linear maintain constraint, wide-angle lens image can be automatically corrected. The geometric correction model is established, and a method of block iterative correction is adopted to eliminate the influence of any uncertainty error. The target in the distorted image can be accurately located in the real scenario.
