System for UGV and UAV to automatically provide laser radar data reference for 3D detection

The invention relates to a system for UGV and UAV to automatically provide their lidar data reference for 3D detection. The system includes two lidar devices, one of which is mounted on the AGV and the other of which is mounted on the UAV. The system also includes a reference unit having a first marker and a second marker in a spatially fixed arrangement relative to each other. An automatic detection of the first marker is performed and a cooperative measurement of the first marker by the first lidar device is performed to determine relative position data providing relative position information of the first marker with respect to the first lidar device. The relative position data and spatial 3D information about a spatially fixed arrangement of the first and second markers with respect to each other are taken into account to perform automatic detection of the second marker and to perform cooperative measurement of the second marker by the second lidar device. Cooperative measurements of the first marker and t
