Embodiment Construction

[0062] The present invention will be further described below in conjunction with examples.

[0063] The data cleaning method of a three-dimensional digital model of an open-pit mine provided by the present invention aims to extract and filter out the main interference information in the three-dimensional digital model—the spatial information of mining equipment, and obtain a three-dimensional digital model that only includes ground elevation information in the pit area. The model is specifically used to identify, locate and filter mining equipment in the three-dimensional digital model of the open-pit mine, that is, to effectively filter out the elevation value data of the equipment, eliminate the interference of the equipment, and restore the original appearance of the mine to a higher degree.

[0064] Such as figure 1 As shown, the data cleaning method of the open-pit mine three-dimensional digital model provided by the embodiment of the present invention includes the follow...

Abstract

The invention discloses a data cleaning method and system for a three-dimensional digital model of a surface mine and a storage medium, and the method comprises the steps: obtaining a surface elevation value of a surface mine region, and building an elevation matrix of the surface mine region, wherein the surface mine area comprises equipment and a pit area where the equipment is located, and eachmatrix element in the elevation matrix corresponds to a position coordinate and an elevation value of each position in the surface mine area; performing standard deviation sampling on the elevation matrix to obtain a standard deviation sampling matrix; converting the standard deviation sampling matrix by adopting a top-hat algorithm to obtain a foreground and background separation matrix, regarding the equipment as a foreground, and regarding a pit area where the equipment is located as a background; secondly, obtaining matrix elements corresponding to the equipment by utilizing the foreground and background separation matrix, and obtaining equipment position coordinates and elevation values according to the matrix elements; and finally, performing interpolation replacement on the equipment elevation value according to an equipment position sampling interpolation method. Through the method, the equipment can be identified, and the data can be cleaned.
