3D Radar Level Scanner for Inventory and Volume Measurement of Grain Silos
Based on terahertz frequency-modulated continuous wave (FMCW) distance measurement, the 3D radar level gauge drives its radar sensor to rotate in multiple dimensions through an internal horizontal rotation and pitch structure to conduct high-resolution panoramic scanning of the silo and the material surface inside the silo. When the radar sensor runs to a predetermined angle, it emits microwave signals from its antenna. After the microwave signals hit the object to be measured, they are reflected and received by the antenna, then the radar sensor moves to the next predetermined angle, and the measurement of the entire detection cycle is completed in this way. The level measurement information corresponding to each angle in the entire detection cycle is obtained. Combined with the angle information, the level measurement information corresponding to each angle and the installation position of the 3D radar level gauge for operation processing, integrating image processing, big data analysis, AI artificial intelligence, machine learning and 3D point cloud conversion, a 3D spatial coordinate system is established to obtain 3D point cloud coordinate values, thereby presenting a 3D visualization image, and calculating relevant parameters such as volume, mass and material level accordingly.
