Abstract

The invention provides a vision-based AGV positioning method. According to the vision-based AGV positioning method, statistical positioning is realized in a manner of configuring a color mark line (2) in an operation path (1) and forming a cross with the operation path (1). The vision-based AGV positioning method aims at the following defects in common vision-based AGV positioning system: single positioning strategy, large accumulative error, easy interference, high mounting cost, etc. The vision-based AGV positioning method has advantages of: abundant information acquisition, multiple positioning strategies, high expandability, low cost, convenient mark configuration, simple and reliable algorithm processing, etc.

Description

technical field [0001] The invention relates to an AGV positioning method, in particular to a vision-based AGV positioning method. Background technique [0002] AGV (Automatic Guided Vehicle) is an unmanned automated transportation device that can carry a certain weight and operate autonomously between the departure point and the destination. It is an important component of the automatic logistics system and flexible manufacturing system. It has good market prospect and application value. The navigation system is the core control part of the AGV, and positioning is an extremely important functional component of the navigation system. [0003] At present, common AGV positioning methods include mileage positioning, inertial positioning, RFID positioning, laser positioning, etc. Their advantages and disadvantages are as follows: [0004] (1) Mileage positioning: positioning is performed according to the traveling distance of the car. This method is simple and easy to use and ...
