Abstract

The invention discloses a method for constructing a navigation map, and belongs to the technical field of robot control. The method comprises the steps of step S1, obtaining an indoor occupied grid map; step S2, establishing a first layer including a passage area, and filling the passage region with a first fill color; step S3, establishing a second layer including an obstacle region, and fillingthe obstacle region with a second fill color; step S4, establishing a third layer, and marking semantic information in the third layer; step S5, merging the first layer, the second layer and the thirdlayer to generate the navigation map. The method has the advantages that the method can obtain the navigation map simply and quickly, distinguishes each area by different colors, and can quickly recognize different obstacles in the navigation map according to the different colors, and the navigation map is added with the semantic information to increase the readability of the navigation map.

Description

technical field [0001] The invention relates to a technology in the field of robot control, in particular to a method for constructing a navigation map. Background technique [0002] Research on mobile robots began in the late 1960s. Mobile robots are a rapidly developing comprehensive technology that integrates the latest research results of multiple disciplines such as computers, electronics, automatic control, and artificial intelligence. [0003] The mobile robot mainly uses multi-sensor fusion technology to obtain various information of the robot itself and its environment, and integrates these information for fusion analysis and processing, so that the robot can understand the current self and the external environment in real time, and make real-time actions. Make motion control decisions, realize basic functions such as avoiding obstacles, finding the optimal path, and performing autonomous movement and path tracking. According to the characteristics of the mobile ro...
