Systems and methods for performing accurate, high-resolution forest inventories within a forest environment. The systems and methods preferably make use of an unmanned aerial vehicle and a ground-based carrier for acquiring first and second initial data frames that are obtained based on point cloud data scanned by a LIDAR mobile mapping system having substantially continuous accessibility to a Global Navigation Satellite System (GNSS) signal.

The invention provides a mobile mapping method, a self-moving device and a storage medium. The method comprises the following steps: planning a first regular moving path in a known area in a map of a working environment, and moving along the first regular moving path to carry out environment exploration; in the moving process, the map is updated according to the explored environment information, and a second regular moving path connected with the first regular moving path is planned according to the updated map; if a to-be-explored area in which a second rule moving path cannot be planned exists in the moving direction and the to-be-explored area is connected with an unknown area in the map, determining a first leading edge position on the boundary of the to-be-explored area and the unknown area; and planning a first navigation path from the current position to the first leading edge position, and moving along the first navigation path for environment exploration. By utilizing the method, the problem of mapping omission caused by the fact that a path planning algorithm cannot generate a regular moving path can be effectively avoided, so that the integrity of the map can be ensured.
