Abstract

An indoor AGV wireless navigation method and a device therefor are disclosed. The method includes collecting in advance indoor overall scene image information including a plurality of marking characteristic points, positioning actual coordinates of the marking characteristic points, building an indoor plane-coordinate system, determining a correlation between the plane-coordinate system and a virtual coordinate system of the scene image information, extracting a safety area of an image according to the scene image information, determining an actual indoor AGV barrier-free travelling safe area according to the correlation between the plane-coordinate system and the virtual coordinate system of the scene image information, detecting present coordinates of an object in real time, and performing route planning in the safe area. The method and the device can automatically recognize route and surrounding environment information, can automatically navigate a vehicle without the need of paving any route information or mark information, and are flexible and free in route planning and high in regulating speed.

Description

technical field [0001] The invention relates to the technical field of AGV wireless navigation, in particular to an indoor AGV wireless navigation method and device. Background technique [0002] AGV based on visual guidance has the characteristics of simple path setting, flexibility, low cost, and easy maintenance and rerouting. Traditional AGV navigation technologies include electromagnetic induction navigation, inertial navigation, laser guidance, visual guidance with fixed paths, and ultrasonic measurement guidance. Citation and other methods, but these methods all need to lay path information and sign information, which leads to a fixed path in actual use. If you need to change the path, you need to change the path information and tag information again, which is troublesome. In practical application, a technology is needed that can automatically identify the path and surrounding environment information, and then make the AGV operate intelligently based on this informat...
