Abstract

The invention discloses an auxiliary positioning member, an autonomous mobile device including the same and a positioning method. The positioning member is characterized in that a plurality of group of auxiliary positioning members are at least arranged in a part of the working area of the autonomous mobile device; when the autonomous mobile device reaches the area of the auxiliary positioning members, an environmental sensing device senses the distance between the autonomous mobile device and the auxiliary positioning members and determines the contour lines of the auxiliary positioning members; and the environmental sensing device positions the auxiliary positioning members based on feature points on the contour lines, or intersection points of the contour lines, or intersection points of the extension lines of the contour lines as positioning points of the groups of auxiliary positioning members. The auxiliary positioning member uses the fixed positioning points for positioning, isaccurate in positioning, and greatly reduces cost.

Description

technical field [0001] The invention relates to an autonomous driving device, in particular to an auxiliary positioning for an autonomous mobile device and an autonomous mobile device containing the same. Background technique [0002] Autonomous mobile devices are used in many industrial situations, for example, delivery trucks in factories and warehouses. According to a common system, magnetic circuits or the like are arranged along the transport route of the truck. Due to the high initial cost, the route of the truck is difficult to change at a later stage, so a system using reflectors was developed. [0003] According to some known systems, reflectors with markings are used, ie from reflected signal instruments on the vehicle it is possible to directly determine which specific reflector the signal came from. Such systems are fast and efficient, but these particular reflectors are relatively expensive. In addition, there are also problems such as the limitation of the d...
