AGV multispectral color discrimination tracking navigation and shape and color positioning method based on visual identification technology

Abstract

The invention relates to an AGV multispectral color discrimination tracking navigation and shape and color positioning method based on a visual identification technology, and the method comprises the following steps of constructing a longitudinal and transverse grid type AGV operation network, employing a plurality of vertical color bands constructed by a first color identifier, employing a plurality of horizontal color bands constructed by a second color identifier. The longitudinal colored bands and the transverse colored bands are respectively crossed to form the longitudinal and transverse grid type AGV operation network, and the intersection points or specific position points of the longitudinal colored bands and the transverse colored bands are the intersection position points or specific position pointsmarked by the specific shapes of the longitudinal colored bands and the transverse colored bands and having both shapes and colors. In the AGV navigation running process, the running route of the AGV is determined through the spectral color visual identification of the longitudinal colored bands and the transverse colored bands, and through visual identification of the position information marked in a shape and color combination mode, the intersection where the AGV passes and the position information are determined, and the AGV runs to a preset terminal point according to the determined running route, the intersection and the position information. The method is applied to the technical field of AGVs.

Description

technical field [0001] The present invention relates to the field of AGV technology, in particular to an AGV multi-spectrum color discrimination tracking navigation and shape-color positioning method based on visual recognition technology. Background technique [0002] In the prior art, the navigation and positioning methods of AGV in the industrial manufacturing environment mainly include the following types: [0003] 1) Rail-type AGV navigation and positioning, this method has a fixed rigid track and a special positioning device, but due to the heavy workload of track laying, rigid route planning, high investment in infrastructure construction, inflexible operation and difficult maintenance, etc. , so it is only suitable for logistics transmission in a small range of bicycles without road crossing and overlapping. In a large-scale industrial manufacturing environment, especially in a production site where multiple AGVs are running at the same time, this method has gradual...
