中文摘要:
针对国产机载激光雷达测深系统海陆波形分类识别的需求,基于多通道海洋激光雷达波形数据的特点,通过提取多通道波形的特征参数,采用支持向量机的方法构建分类模型对海陆波形进行分类。通过检验结果证明,该分类方法总体精度和Kappa系数分别达99.03%和0.9805。该方法海陆波形分类精度满足工程应用需求,适用于国产机载激光雷达测深系统的波形分类处理,为后续深度计算过程中水体介质光速校正和潮汐波浪改正奠定基础。

英文摘要:
To solve the problem of sea and land waveform classification for domestic airborne lidar bathymetric system,support vector machine method is used to build the model for classification of sea and land waveform.This method is based on the features of multi-channel ocean lidar waveform data,and characteristic parameters of multichannel waveform are extracted.The validation results indicate that overall accuracy and Kappa coefficient of the classification method are 99.03%and 0.9805,respectively.The accuracy of the sea and land waveform classification of the proposed method is good enough for the engineering application.And it is suit for the waveform classification treatment of domestic airborne lidar bathymetric system.Which can lay the foundation for correcting the velocity of light in the water medium during the depth calculation procedure,tide and wave correction.
