红外激光图像中的远小特征定位方法
|
摘要
针对红外激光图像远小目标像素特征模糊,定位困难的问题。设计一种红外激光图像中的远小特征定位方法,远红外对目标物体表面弯曲度进行隐性干扰,缩减噪音辐射对激光雷达图像特征的干扰,实现对软件功能模块的开发。功能模块在远红外特定定位技术下,使用多普勒模型、电离层隔离方法和递归神经网络对激光雷达图像特征进行提取、修正和定位。实验结果证明,所设计的定位软件具有极高的定位精度,并且定位时延较小。
Aiming at the infrared laser image,the target pixel is fuzzy,and the problem of locating is difficult.Design a far smaller features in the images of the infrared laser location method,far-infrared recessive of target object surface curvature interference,reduce noise radiation of laser radar image characteristics of interference,implementation of the development of software function module.Function modules in far-infrared specific positioning technology,the use of doppler model,the ionospheric isolation method and recursive neural network to the laser radar image features extraction,correction,and positioning.The experimental results show that the positioning software is very accurate,and the positioning delay is small.
