基于图像信息的雷达测距系统实现

研究雷达图像测距问题,提高测量结果的准确性。针对当雷达采集图像中,测距点的像素与外界环境像素混淆,无法通过灰度等级进行准确的提取,导致测距点采集存在误差,根据测距点进行的距离测量结果准确性不高的问题。为了解决上述问题,提出一种新的基于雷达远程采集图像的距离测定方法。通过运用特征点的亚像素级精确配准技术,使得待检测的测距点能够完成准确的匹配,保证距离计算结果的精确性。实验结果表明,改进方法能够快速的完成关于雷达采集图像的距离测定,提高了测距的准确性,取得了不错的效果。

Based on Image Information System of Radar Range

Research the radar image of distance measurement to improve the measurement results of accuracy.In the radar image,the pixels at collection point and the pixels at outside world range are confused,so that the accurate extraction can not be carried out through the environment pixel gray level,leading to some error existing in collection points and low accuracy based on the location of distance measurement points.In order to solve this problem,we put forward a new remote acquisition method based on radar image of distance measurement.Using the feature point and pixel level accurate registration techniques,the feature points to be tested were able to complete the accurate matching,and guaranteed the accuracy of the calculation results distance.The experimental results show that this method is able to quickly complete collection of radar image based on distance measurement and improve the accuracy of the location.
