Abstract

The invention is applicable to the field of mobile robots, and provides a positioning method implemented by a positioning system. The positioning system comprises a mobile platform, and a first marker and a second marker which are preset. The method comprises the following steps: acquiring image information of the first marker and the second marker through an image acquisition unit; processing the image information through an image processing unit, and outputting image processing results; and according to the image processing results, preset parameters of the image processing unit, location information of the first marker and location information of the second marker, carrying out calculation to obtain current location information of the mobile platform relative to the first marker and/or the second marker. The method provided by the invention has the advantages that the mobile platform can be accurately positioned, and the positioning precision is high, so that the mowing efficiency is greatly improved, and the mowing coverage is greatly enlarged; and equipment adopted in the method is low in cost, and does no harm to human bodies, so that high safety is achieved.

Description

technical field [0001] The invention belongs to the field of robots, and in particular relates to a positioning method, device and system. Background technique [0002] With the development of science and technology, a large part of the work that requires more manpower has been replaced by machines. For example, with the development of economy in our country, the area of ​​lawn is increasing rapidly, and the lawn must be mowed regularly, otherwise it will affect the overall appearance of the lawn, and regular mowing can also promote the tillering of the grass, making the lawn denser. Avoid the habitat of insects, snakes and other animals that affect people's health. Therefore, mowing robots are becoming more and more popular, and how to automatically mow grass has become a hot research topic. [0003] In order to improve mowing efficiency and mowing coverage, some of the existing mowing robots use GPS positioning technology, but the positioning accuracy of this mowing robo...
