| description | The invention belongs to the field of electronics, and provides a positioning method and a positioning device. According to the positioning method, the positioning device acquires the first positioning data of the position at which the positioning device is positioned through a sensor; the first area map of the area at which the positioning device is positioned is generated according to the firstpositioning data; the first area map is subjected to local matching in a global map; and if the first matching result of the local matching of the first area map in the global map is greater than or equal to a preset threshold, the positioning device determines the position of the positioning device according to the first matching result. According to the present invention, by using the local mapmatching method, the positioning efficiency is improved and the resources (such as computing resources and storage resources) required by the positioning is saved compared to the positioning method using the complex algorithm |
