Problems solved by technology

[0003]The existing AGV navigation methods are mainly magnetic stripe guidance, laser guidance and other methods, but these methods have their own limitations. In recent years, with the advancement of technology With the development of advanced technology, some new positioning and navigation technologies have also emerged, such as the automatic guided vehicle navigation method based on two-dimensional code positioning published by Chinese patent number CN201410296320.6. This visual guidance method can effectively improve the path design of automatic guided vehicles. flexibility, but it needs to place a large number of two-dimensional code labels at equal intervals, and the automatic guided vehicle will generate cumulative errors after running for a long time. derailed

Embodiment Construction

[0023] The present invention and the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0024] combine figure 1 , figure 2 , image 3 The present invention is described as follows:

[0025] A navigation method for an inertial guided vehicle based on two-dimensional code positioning, comprising the following steps:

[0026] Step A), set a ground coordinate system for the ground 4 of the application site of the inertial guided vehicle, set multiple two-dimensional code labels 3 on the ground 4 of the application site, so that the two-dimensional code labels 3 form a grid, and each two-dimensional code label 3 are printed with stored two-dimensional code label 3 position coordinate information and the distance information between the adjacent two-dimensional code label 3; The two-dimensional code label can also be arranged with irregular intervals, and this embodiment...

Abstract

The invention discloses a inertial guidance vehicle navigation method based on two-dimensional code positioning, and an inertial guidance vehicle based on the navigation method. According to the inertial guidance vehicle navigation method and the inertial guidance vehicle, a two-dimensional code label is arranged on a site, real-time online calibration can be carried out on a trajectory of the inertial guidance vehicle during the operation process thereof, the possibility of derailment is avoided, and objects on the inertial guidance vehicle can be fetched more accurately through a feedback adjustment of a position of a fetching mechanical arm at a target point.

Description

technical field [0001] The invention belongs to automatic vehicle navigation technology, and mainly relates to a navigation method of an inertial guided vehicle based on two-dimensional code positioning and the inertial guided vehicle. Background technique [0002] With the development of industrial automation technology, automatic guided vehicles (AGV) are widely used. Automatic guided vehicles can automatically run according to the route of instructions without human intervention, so it can effectively improve industrial automation and improve transportation efficiency. [0003] The existing automatic guided vehicle navigation methods are mainly magnetic strip guidance, laser guidance and other methods, but these methods have their own limitations. In recent years, with the development of science and technology, some new positioning and navigation technologies have also appeared, such as China Patent No. CN201410296320.6 discloses a navigation method for automatic guided...
