基于多波长沙氏激光雷达的植物表型检测系统和方法
By using a multi-wavelength Saxony lidar system, the simultaneous acquisition of structure and spectrum and high-precision three-dimensional reconstruction in plant phenotyping were achieved. This solved the problems of insufficient depth-of-field imaging and lack of multi-wavelength spectrum acquisition in existing technologies, and reduced system complexity and cost.

Abstract
本发明提出了一种基于多波长沙氏激光雷达的植物表型检测系统和方法。系统包括激光发射组件和接收成像组件，其中激光发射组件用于发射多波长共轴的片状激光照射植物目标，不同波长对应植物组织在不同光谱波段的反射特性差异；接收成像组件包括接收镜头和图像传感器，接收镜头的光轴与图像传感器成像平面之间的夹角被配置为满足沙氏成像条件，使片状激光照射范围内的物点能够在图像传感器上清晰成像。所述方法包括：对多波长激光反射信号进行成像采集，基于图像传感器多通道光谱响应特性对成像信号进行响应校正与解耦，获取多波长反射强度信息，并结合三维点云数据与多波段光谱特征实现植物结构识别与表型参数提取。
