| description | The embodiment of the invention discloses a mine exploration section line extraction method and device, computer equipment and a storage medium. The method comprises the following steps: intersecting section lines with a mine boundary, and calculating a starting point coordinate and an end point coordinate of each section line; extracting a profile line from the profile map, and extracting a coordinate axis to obtain an X datum line and a Y datum line; inflection points of the section lines are extracted; calculating the relative distance between the inflection point and the X datum line; determining the elevation value of each inflection point; calculating the relative distance between the inflection points and the Y datum line, and endowing the relative distance corresponding to the left inflection point of the Y datum line as a negative value; calculating X and Y coordinate values of each inflection point; determining a three-dimensional surface of the inflection point; a model is established through secon |
