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。
In order to meet the needs of land-sea waveform classification and recognition of domestically-produced airborne lidar system, based on the characteristics of multi-channel laser radar waveform data, the classification model was constructed by extracting the parameters of multi-channel waveform and using support vector machine . The test results show that the overall accuracy of the classification method and the Kappa coefficient were 99.03% and 0.9805. This method can meet the needs of engineering applications and can be applied to the waveform classification of domestically produced airborne laser radar sounding system, which lays a good foundation for the correction of water velocities and tidal wave correction in depth calculation.
