The invention discloses a laser radar intelligent management and control method and system in city-level live-action three-dimensional construction, and the method comprises the steps: obtaining the live-action image information of a city target region, analyzing the complexity of a live-action through the preprocessed live-action image data, and carrying out the division and data annotation of the target region; different numbers of laser radar devices are distributed to the sub-regions, local path planning is carried out, and the laser radar devices are scheduled according to the laser scanning time corresponding to different sub-regions; acquiring point cloud data by using a multi-laser radar device, registering the preprocessed point cloud data, and extracting point cloud semantics of the sub-regions to perform point cloud block fusion; and acquiring a global point cloud after fusion of the point cloud blocks to carry out scene identification, and carrying out scene labeling in live-action three-dimension
