Title:

DATA PROCESSING METHOD AND APPARATUS

Document Type and Number:

WIPO Patent Application WO/2020/063878

Kind Code:

A1

Abstract:

A data processing method comprises: acquiring data of each three-dimensional point in a first three-dimensional point set (S210), the data of each three-dimensional point in the first three-dimensional point set being acquired by a smart device when being at a first position, the first three-dimensional point set including a plurality of three-dimensional points located in a first coordinate system; determining, from the first three-dimensional point set, a first sub three-dimensional point set (S220), the first sub three-dimensional point set forming a first plane; calculating a plurality of first distances (S230), a first distance being the distance between a first three-dimensional point and the first position, the first three-dimensional point being any one three-dimensional point in the first sub three-dimensional point set; according to the plurality of first distances, determining, from the first sub three-dimensional point set, a first target three-dimensional point (S240); and using the first target three-dimensional point as a constraint condition, to locate the smart device, and acquire the pose thereof at the first position (S250). The method reduces the overheads of computing resources and computing time, improving the running efficiency of the whole SLAM process.
