Problems solved by technology

The advantage is that the initial position and attitude are relatively accurate, but the limitation is that the real-time position and attitude correction of the robot cannot be achieved. As the robot runs longer, and the ground bumps or slips, a higher navigation error will be accumulated.

Abstract

The invention discloses a navigation method and system. The method comprises the following steps that: receiving a first movement instruction, wherein the first movement instruction is used for carrying out instruction movement to a target position; obtaining a positioning point; forming a second movement instruction, wherein the second movement instruction is used for carrying out instruction movement to the positioning point; according to the second movement instruction, moving to the positioning point; forming a third movement instruction on the positioning point, wherein the third movementinstruction is used for carrying out instruction movement to the target position; and according to the third movement instruction, moving to the target position. By use of the method, navigation errors are lowered, and task execution fluency is improved.

Description

technical field [0001] The invention relates to the technical field of navigation, in particular to a navigation method and system. Background technique [0002] Indoor navigation generally adopts laser real-time positioning and map construction (Simultaneous Localization And Mapping, SLAM) navigation algorithm, visual SLAM navigation algorithm, ultrasonic SLAM navigation algorithm, etc. Such algorithms generally use laser, camera, ultrasonic combined with odometer to accumulate and settle navigation position information. The advantage is that the initial position and attitude are relatively accurate, but the limitation is that the real-time position and attitude correction of the robot cannot be achieved. As the robot runs longer, and the ground bumps or slips, a higher navigation error will be accumulated. Contents of the invention [0003] The invention provides a navigation method and system to reduce navigation errors. [0004] One aspect of the present invention pro...
