Embodiment Construction

[0023] Such as figure 1 , 2 As shown, the on-the-spot dynamic detection method of the open-pit mine of an embodiment of the present invention generally comprises the following steps:

[0024] Step 100, select a 3D laser scanner device according to requirements, divide the scanning area of ​​each 3D laser scanner device at the same time, and then arrange the 3D laser scanner device in each scanning area.

[0025] When selecting 3D laser scanner equipment, it is necessary to consider the size, accuracy and environmental suitability requirements of the current open-pit mine.

[0026] When dividing the scanning area, it is necessary to consider the overall scope of the open-pit mine, the stripping surface, the geomorphic shape of the on-site mining, the distribution of features, the on-site construction status equipment and the range that the 3D laser scanner equipment can cover, and then determine the 3D laser scanning. On-site station layout of instrumentation equipment.

Abstract

The invention provides an on-site dynamic detection method for a surface mine. The method comprises the following steps of step 100, selecting three-dimensional laser scanner devices according to the requirement, simultaneously dividing the scanning area of each three-dimensional laser scanner device, and then arranging the three-dimensional laser scanner devices in each scanning area; step 200, establishing a common feature point cloud between adjacent scanning areas, and then sequentially starting the three-dimensional laser scanner devices of each scanning area to scan the scene and obtain regional point cloud data; step 300: subjecting the regional point cloud data to point cloud stitching, point cloud pruning and coordinate system conversion to obtain the whole point cloud data; and step 400, using a tool to deal with the whole point cloud data to obtain the actual data of the current surface mine and the 3D visualization image. The method is based on the three-dimensional laser scanning technique, can recover the space shape of the surface mine at the selective examination time, and enable the three-dimensional management mode to gradually replace the two-dimensional mode.

Description

technical field [0001] The invention relates to the field of mine exploration, in particular to a method for on-the-spot verification of mining rights in open-pit mines and a dynamic detection method for reserves based on three-dimensional laser scanning technology Background technique [0002] In the spot check of whether the open-pit mine meets the specified mining requirements, the total station or RTK is mainly used to measure the stripping surface, and the outline of the stripping surface is used to discretely coordinate the mining points to analyze whether the cross-border situation of the open-pit mine meets the regulations. , producing resources and reserves are calculated using the construction profile method. This method of random inspection mainly has the following defects: [0003] (1) Since the coordinates of the key points on the boundary of the mining stripping surface are collected, point information other than the key points cannot be obtained, so the entir...
