Embodiment Construction

[0044] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is said to be "fixed" to another element, it may be directly on the other element, or there may be one or more intervening elements therebetween. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", and "bottom" used in this specification is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the The invention and the simplified description do not indicate or imply that the device or element referred to must have a specific orientation...

Abstract

The embodiments of the present invention provide a map construction method and a robot thereof. The map construction method includes: acquiring a two-dimensional point cloud image of a motion space, where the two-dimensional point cloud image is a data set composed of several point cloud data; determining a wall in the motion space according to the two-dimensional point cloud image; The wall determines the main direction of walking. The method adds a main walking direction search function, which can provide the robot with the best main walking direction, so that the composition is more flat, regular, intuitive, and conforms to the user's usage habits, which is beneficial to improve the user's experience.

Description

【Technical field】 [0001] The invention relates to the technical field of automation control, in particular to a map construction method and a robot thereof. 【Background technique】 [0002] SLAM (simultaneous localization and mapping, real-time positioning and map construction) is a related method used to achieve the following problems: put a robot into an unknown position in an unknown environment, let the robot gradually draw a complete map of the environment, and travel without obstacles to every accessible corner or area. [0003] SLAM has been widely used in related robotic fields such as intelligent sweeping robots, and is a research hotspot today. During the movement of existing sweeping robots, etc., they usually use a random scanning method to randomly judge the obstacles in their vicinity to compose a picture, and finally determine the walking path of the robot according to the composition structure. [0004] Such a composition and the corresponding walking path a...
