Abstract

The invention discloses a medium printed with a positioning identifier, an image processing method and an automatic guided vehicle. An image with higher anti-interference performance is obtained through a positioning graph which is arranged on the periphery of an identifier pattern and has a line width larger than that of a locator. The image is used for two-dimensional code navigation, so that after acquiring a to-be-recognized image, the automatic guided vehicle can recognize the positioning graph at first, determine a to-be-recognized region in the to-be-recognized image according to the recognized positioning graph, and then perform identifier pattern decoding and position information determination on the to-be-recognized region for navigation. The line width of the positioning graph is larger than that of the locator, so that the anti-interference performance of the positioning graph is higher, the region where the identifier pattern is located in the to-be-recognized image can be quickly recognized through the positioning graph, and the recognition speed and the robustness of two-dimensional code navigation are improved.

Description

technical field [0001] The application relates to the technical field of warehousing and logistics, and in particular to a medium printed with a positioning mark, an image processing method, and an automatic guided vehicle. Background technique [0002] At present, automated handling equipment such as automated guided vehicles (Automated Guided Vehicle, AGV) have been widely used in warehousing, logistics and other fields to realize automated transportation of goods. [0003] In the existing technology, one of the mainstream AGV navigation solutions is that the AGV recognizes the identifier pattern set on the warehouse floor through the camera installed on the vehicle body, and performs navigation and positioning. Since the commonly used identifier pattern is a two-dimensional code Therefore, this method is often called QR code navigation. The prerequisite for two-dimensional code navigation to be realized is that the AGV can recognize the two-dimensional code through the c...
