The invention discloses a construction site management and control method and device, and the method comprises the steps: obtaining initial point cloud data obtained by scanning a target construction site through a three-dimensional laser scanner; acquiring coordinates of a plurality of key control points of the target construction site acquired by the RTK equipment; converting the initial point cloud data into a target coordinate system based on the coordinates of the plurality of key control points to obtain converted point cloud data; preprocessing the converted point cloud data to obtain target point cloud data of the target construction site; generating an initial construction site map based on the target point cloud data; adding the initial building three-dimensional model of the target building to the initial construction site map to obtain a target construction site map; and performing event detection based on the real scene image of the target construction site, and outputting an event detection result. The accuracy of construction site management and control can be improved.
