Laser positioning system and method based on AGV

Abstract

The embodiment of the invention discloses a laser positioning system and method based on an AGV. The laser positioning system based on the AGV comprises a scene map which comprises at least two presetposition points and at least two reflective marker groups which are respectively fixed at the at least two preset position points, wherein each reflective marker group comprises at least two reflective markers, and the reflective markers in different reflective marker groups are different; one reflective marker group comprises information of a preset position point; the reflective marker group isused for acquiring the preset position point information after being scanned by a laser scanner of the AGV. Compared with technologies of the prior art, different position points in the scene map aredistinguished on the basis of relatively low cost, and therefore the AGV or the position of the target point is positioned.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of laser navigation, and in particular to an AGV-based laser positioning system and method. Background technique [0002] Automated Guided Vehicle (AGV) is equipped with automatic guidance devices such as electromagnetic or optical, can drive along the prescribed guiding path, and has safety protection and various transfer functions. AGV has the advantages of high degree of automation and charging automation, and has been more and more widely used in industries such as warehousing, logistics and manufacturing. [0003] In the existing technology, there are many AGV guidance methods, including electromagnetic induction guidance, laser guidance and vision guidance. Among them, a laser scanner is installed on the laser-guided AGV, and the distance of the detected object can be obtained by calculating the time difference between laser emission and reception. The later the reflected wave is...

[0004]However, the scene map often includes multiple target points. In the charging station scene, the target point is the charging station. charging stations, each charging station needs to be made into a different shape, which will undoubtedly increase the cost of the system

However, if the contours of charging station No. 1 and charging station No. 2 are the same, the AGV cannot distinguish between the two charging stations.
