Multi-source information fusion-based fullness rate identification method and system
The invention relates to the technical field of non-contact measurement, in particular to a multi-source information fusion-based bucket fullness rate identification method and system, and the method comprises the steps that a central processing unit calculates the volume of a first material shoveled into a bucket according to a material pile point cloud before spading operation and a material pile point cloud after spading operation; the laser radar collects multi-frame point clouds under multiple poses of the loader, the first displacement sensor, the second displacement sensor and the angle sensor collect the pose information of the loader, and the central processing unit calculates the volume of a second material shoveled into the bucket; the central processing unit calculates the volume of a third material shoveled into the bucket according to the pose information, the pressure of large and small cavities of the movable arm oil cylinder and the rotating bucket oil cylinder and the preset material density; and the central processing unit calculates the comprehensive fullness rate of the loader according to the first material volume, the second material volume and the third material volume. According to the invention, the measurement precision of the full-fill rate can be improved.
本发明涉及非接触式测量技术领域，特别是指一种基于多源信息融合的满斗率识别方法及系统，方法包括：中央处理单元根据铲掘作业前的料堆点云和铲掘作业后的料堆点云，计算铲斗内铲入的第一物料体积；激光雷达采集装载机多个位姿下的多帧点云，第一位移传感器、第二位移传感器和角度传感器采集装载机的位姿信息，中央处理单元计算铲斗内铲入的第二物料体积；中央处理单元根据位姿信息、动臂油缸和转斗油缸的大小腔压力、以及预设的物料密度，计算铲斗内铲入的第三物料体积；中央处理单元根据第一物料体积、第二物料体积和第三物料体积，计算装载机的综合满斗率。采用本发明，可以提高满斗率的测量精度。
