The embodiment of the invention provides a three-dimensional map creating method and device and surveying and mapping equipment, and relates to the technical field of surveying and mapping. The method is applied to surveying and mapping equipment, the surveying and mapping equipment comprises a non-repeated scanning laser radar, and the method comprises the following steps: based on an SLAM technology, carrying out dynamic scanning by using the laser radar to obtain a global map of a target area; determining a target local area in the global map; planning a plurality of control points in the target local area; controlling the laser radar to move to each control point, and performing static scanning at each control point to obtain a target local map of the target local area; and splicing the target local map on the global map to obtain a target three-dimensional map. Therefore, the non-repetitive scanning laser radar is utilized, the same set of hardware equipment supports a dynamic and static mixed surveying
