WU Xiao-qing · Journal of Henan University of Technology · 2009
The reverse-engineering-based method for mass measurement of large grain stack with irregular shape was proposed.Through repeated measurements,the multi-view point cloud data of grain stack surface can be obtained and the 3D surface model can be reconstructed after point cloud data registration.The volume of the stack can be calculated through image acquisition,data analysis and 3D reconstruction.After measuring density of grain samples,the mass can be calculated through the volume and density of the grain stack.The result of the experiments of rice stack shows that the measuring error of the system is lower than 1%.It is suitable for the mass measurement of grain stack with irregular shape.
