Abstract

The invention discloses a method and a device for establishing a three-dimensional map. The method comprises the following steps: determining sensing data corresponding to a target space; determining an initial three-dimensional map according to the sensing data by using a three-dimensional engine; processing the initial three-dimensional map to determine a target three-dimensional map corresponding to the target space. According to the three-dimensional map establishing method and device provided by the invention, the three-dimensional map for the target space is determined, so that the shape structure of the target space and the three-dimensional relationship of the objects in the target space are reflected; the intelligent device can complete richer function implementation by using the three-dimensional map, and the function requirements of the intelligent device are better met.

Description

technical field [0001] The invention relates to the technical field of three-dimensional maps, in particular to a method and device for establishing a three-dimensional map. Background technique [0002] In the field of robotics at present, the realization of many functions needs to rely on the virtual map function of the robot. That is, the robot perceives its physical environment through sensors, and builds a virtual map based on the spatial structure of the physical environment. Subsequent functions such as navigation and route planning can be completed based on the virtual map. [0003] In the prior art, sensors such as laser radars and infrared cameras are usually used to realize the perception of the physical environment, obtain corresponding point cloud images, and realize the construction of virtual maps based on the point cloud images. However, the virtual map established according to the above method is a planar map, and generally does not contain the three-dimen...
