Embodiment Construction

[0043] The specific implementation manners of the present application will be further described in detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present application, but not to limit the scope of the present application.

[0044] First, some terms involved in this application are introduced.

[0045] Euclidean transformation: used to describe the rotation relationship between two coordinate systems, plus translation, collectively referred to as the transformation relationship between coordinate systems. In the Euclidean transformation, the transformation is described by a rotation matrix R and a translation vector t. The rotation matrix R and the translation vector t can be combined into a matrix, so that the entire transformation relationship becomes a linear relationship. The combined matrix T is the transformation matrix (Transform Matrix).

Abstract

The invention relates to a data processing method and device for position data and a storage medium, and belongs to the technical field of computers. The method comprises the steps of: obtaining first position data collected by a sensor assembly in the moving process of self-moving equipment; acquiring first true value data corresponding to the first position data; determining a transformation matrix by using the first position data and the first truth value data based on a nonlinear optimization mode; and converting second position data acquired by the sensor assembly into a second coordinate system by using the transformation matrix to obtain converted position data. The problem that errors exist in obtained results when the position data are directly analyzed and processed due to the fact that the position data collected by different sensor assemblies are determined based on different coordinate systems can be solved. Converted position data can be compared and analyzed in the same coordinate system, and the accuracy of position analysis is improved.

Description

【Technical field】 [0001] The present application relates to a data processing method, device and storage medium of location data, belonging to the field of computer technology. 【Background technique】 [0002] Existing self-mobile devices often have a positioning function. At this time, the self-mobile device usually collects the location data of the working area through the sensor component, and analyzes and processes the location data to realize the positioning function. [0003] Since there are generally many sensor components used for positioning on a mobile device, the coordinate system of each sensor component is usually determined based on the location of the sensor component. For example, a coordinate system is established with the position of the sensor component as the coordinate origin, and the position data collected by the sensor component is determined based on the coordinate system. [0004] However, this will cause the position data collected by different se...
