Laser scanning technology in assessing the volume of bulk materials
Keywords:bulk materials, construction, transportation, laser, scanning
The article discusses the application of laser scanning technology to assess the volume and mass of bulk materials, as well as the construction of the 3D models on the basis of data obtained. The developed device has practical application in construction. Bulk raw materials is a significant part of the costs of the enterprises and it is necessary to control its volume for the efficient distribution. The required accuracy of volume determination depends on the cost per unit volume of bulk material and can vary widely. The problem with measurement is that the volume/mass of cargo is often falsified by freight forwarders and shipping companies. In order to solve this problem it is necessary to develop a set of methods and special devices for rapid assessment of the volume of bulk materials carried in the car body before its unloading. It was found that customers of bulk materials such as gravel, crushed stone, sand lose at least 16% of the cargo on average. This value is essential, since the required accuracy of determining the volume depends on the cost per unit volume of bulk material and can vary widely. The proposed method will help to make it 85% lower, i.e. down to 2.2%
