Abstract

The invention relates to a granary grain volume measurement system, which comprises a first laser radar device, a second laser radar device and a computing terminal, and is characterized in that the first laser radar device and the second laser radar device are installed at diagonal positions of two ends above the interior of a granary; and the first laser radar device, the second laser radar device and the computing terminal are located in the same local area network, and the computing terminal is in communication connection with the first laser radar device and the second laser radar device. Because the first IMU data and the second IMU data are used in the measurement and calculation process, after the first rotation matrix and the second rotation matrix are calculated, any point in the first point cloud data and the second point cloud data is converted into the granary overall coordinate system from the first rotation matrix and the second rotation matrix, and compared with one-dimensional linear scanning, the precision is higher, the error is smaller, and the volume of the granary can be calculated more accurately.

Description

technical field [0001] The invention relates to the technical field of laser radar, in particular to a granary grain volume measurement system. Background technique [0002] The English full name of laser radar is Light Detection And Ranging, referred to as LiDAR, that is, light detection and measurement. It is a system that integrates three technologies: laser, global positioning system (GPS) and IMU (Inertial Measurement Unit, inertial measurement unit). Used to acquire data and generate accurate DEMs (Digital Elevation Models). The combination of these three technologies can highly accurately locate the spot of the laser beam on the object, and the distance measurement accuracy can reach centimeter level. Based on this advantage, lidar is widely used in application scenarios such as 3D reconstruction and vehicle-road coordination. [0003] At present, the Internet of Things technology has been widely used in granaries, such as using temperature sensors deployed in multi...
