The invention discloses a method and
system for measuring the volume of a dry bulk material
pile by using a storage
yard camera, and the method comprises the steps: installing a high-definition camera at the periphery of a storage
yard or on mobile operation equipment, and collecting the image data of the storage
yard; preprocessing the data; carrying out
image matching based on an improved SIFT
algorithm; reconstructing a three-dimensional structure of the storage yard; wherein the improved SIFT
algorithm specifically comprises the following steps: during
feature point matching, performing rough matching on feature points according to
Euclidean distance, connecting rough matching pairs, comparing an included angle between connecting lines with a preset angle threshold value, removing wrong matching pairs, obtaining
feature point matching pairs after fine matching, and performing
image matching; segmenting and extracting
point cloud data of the material
pile, converting the
point cloud data into a triangular
network model, and calculating the volume of the material
pile by using definite integral with the ground of the storage yard as the bottom surface. The method can be specifically applied to large dry
bulk cargo collecting and distributing port stations or warehouses such as ports, power plants and
coal storage bases, and the material pile volume of a storage yard can be rapidly and accurately obtained in real time.
