Three-dimensional digital model construction method for green mine assessment

The invention relates to the field of data processing, in particular to a three-dimensional digital model construction method for green mine assessment, and the method comprises the steps: obtaining the point cloud data of the overall terrain of a to-be-assessed mine; preliminarily determining a suspected abnormal terrain area in the overall terrain according to the point cloud data; determining the possible degree that the current suspected abnormal terrain area is caused by human activities by using the terrain structure parameters and the point cloud data of the current suspected abnormal terrain area and the adjacent suspected abnormal terrain area; constructing a three-dimensional digital model of the to-be-assessed mine according to the possible degree and the assessment result of other terrain areas except the suspected abnormal terrain area in the overall terrain; and assessing the to-be-assessed mine through the three-dimensional digital model to determine whether the to-be-assessed mine reaches the
