(Summary description)Lidar scanning technology extends single station scanning to overall scanning by continuously, quickly, large-area, and non-contact scanning of irregular and complex surfaces. It quickly reconstructs geometric data such as points, lines, surfaces, and 3D models of the surface, allowing for a detailed understanding of the overall changes and detailed features of the survey object.

Information

Lidar scanning technology extends single station scanning to overall scanning by continuously, quickly, large-area, and non-contact scanning of irregular and complex surfaces. It quickly reconstructs geometric data such as points, lines, surfaces, and 3D models of the surface, allowing for a detailed understanding of the overall changes and detailed features of the survey object. This method of collecting data from multiple directions and angles to obtain more three-dimensional information of the measured object, and establishing three-dimensional visualization data can more realistically reflect attribute features such as geographical location, appearance, and height.

1.Measurement of truck volume measurement system

Lidar technology is an innovative volume measurement tool in the field of volume measurement. Lidar can accurately measure the volume of objects in a short period of time, while also adapting to various shapes and sizes of objects. It uses millimeter level LiDAR, area array scanning, and single line LiDAR to scan vehicles. Measuring high-precision volume data requires sufficient density of point cloud data, which is filtered through point cloud to obtain reliable point cloud data. Then, point cloud sampling is carried out to reduce point cloud data, while preserving point cloud morphological features to reduce computational complexity. Then, through slicing, the point cloud is sliced along a certain coordinate axis direction, Calculate the area of the upper and lower surfaces of the slice again, and calculate the total volume by accumulating the slice volume. First, measure the volume information of the empty vehicle body, and then measure the volume information of the loaded goods. The difference between the two is the volume of the loaded goods.

 

 

2.Volume measurement of belt conveyor lines
The laser scanner can obtain the two-dimensional contour (single cross-section) of the material in one scan. When the belt conveyor line is running, the scanner continuously scans and combines the information of the conveyor line speed (usually obtained through an encoder) to calculate the volume of coal being transported.
