Abstract
The present disclosure relates to a positioning apparatus and method and a self-moving device. The positioning apparatus includes a first positioning module (), a sensor module (), and a processing module (). The position of the positioning apparatus is determined according to the positioning result of the first positioning module () and the positioning result determined by using the sensor module () to measure the acceleration and the angle parameter and based on a pedestrian dead reckoning algorithm, and determine the boundary of the self-moving device. A pedestrian dead reckoning technology independent of an external environment is introduced during boundary positioning, and the pedestrian dead reckoning technology and other positioning technologies are integrated to establish a virtual boundary, so that positioning precision is high, and a precise boundary is established. In addition, it is not necessary to arrange a physical boundary, so that operations of a user are less complex.
