The invention provides a material pile three-dimensional reconstruction method and device, electronic equipment and a storage medium. The method comprises the steps: controlling a laser transmitter to transmit a laser grid to a material pile, and enabling the laser grid to completely cover the material pile; an collection device acquires two grid images of the material pile at different angles under the irradiation of the laser grid; pixel coordinates of target pixel points in the two grid images in each grid image are obtained; respectively inputting the pixel coordinates of the target pixel points in each grid image into a trained coordinate prediction model to obtain the world coordinates of the material pile; and establishing a three-dimensional model of the material pile according to the world coordinates of the material pile. According to the method, the material surface is covered by means of the laser grids, the two collection devices acquire the laser grids, perform feature extraction and then perform matching, and the coordinate prediction model performs three-dimensional reconstruction of the material surface through the collected feature points, so that the defect of various calibration parameters is reduced, the accuracy is higher, and the operability in a dark environment is high.
Description
technical field [0001] The present application relates to the technical field of three-dimensional reconstruction, and in particular, relates to a method, device, electronic device and storage medium for three-dimensional reconstruction of a material pile. Background technique [0002] In the field of engineering, large-scale solid material piles need to measure three-dimensional landform parameters, mass, volume and other effective parameters, such as furnace piles in blast furnaces, materials stacked in ports, grain stored in granaries, coal piles in power plants, ores in mines rocks etc. [0003] For resource-based enterprises, such as thermal power plants, steel yards, granaries, etc., the inventory management process of materials is an important part of evaluating the benefits of enterprises, which directly affects the production costs of enterprises. In order to improve the economic benefits of enterprises, it is necessary to accurately and quickly measure the volume ...
