Volume Measurement Method for Industrial Material Boxes Based on Depth Camera
This paper presents a method of measuring the volume of industrial tank based on depth camera.Firstly,the depth camera is used to obtain the initial point cloud of the scene,and the bin point cloud is obtained after preprocessing the point cloud,and the upper surface of the bin point cloud is extracted.The point cloud void filling algorithm is used to fill the point cloud void.Because the point cloud distribution is not uniform,the voxel filtering algorithm based on octree is selected to homogenize the point cloud.Then,the point cloud centroid is calculated,and the point cloud of the material box is transformed by taking the centroid as the coordinate origin.The length and width of the upper surface of the mate-rial box are obtained by using the point cloud coordinates of the characteristic plane.The height is calculated by the differ-ence between the height of the pretreatment bottom and the upper surface,and the volume of the material box is finally calculated.
