Abstract: This application relates to the field of artificial intelligence. The technology includes: obtaining data of each three-dimensional point in a first three-dimensional point set, where the data of each three-dimensional point is collected when an intelligent device is in a first position, and the first three-dimensional point set includes a plurality of three-dimensional points located in a first coordinate system; determining a first three-dimensional point subset from the first three-dimensional point set, where the first three-dimensional point subset forms a first plane; calculating a plurality of first distances, which is a distance between a first three-dimensional point and the first position; determining a target first three-dimensional point from the first three-dimensional point subset based on the plurality of first distances; and locating the intelligent device by using the target first three-dimensional point as a constraint to obtain a pose of the first position.
