Problems solved by technology

Laser navigation technology has many advantages, but its navigation accuracy is still low. Generally, the accuracy of navigation based on laser radar can only reach 5CM. For some usage scenarios, the accuracy is far from enough
With the technology of two-dimensional code navigation, it is necessary to set up two-dimensional codes densely in the work area. Generally, one or two meters should be set up one two-dimensional code. Since the two-dimensional code records important information and is easy to wear and tear, it is necessary to carry out the two-dimensional code Regular maintenance, this process is more cumbersome

Abstract

The invention discloses an integrated navigation method with fusion of laser radar and two-dimensional code, a device and a system. The integrated navigation method comprises the following steps: driving a carrier to move to an estimated position closing to a marked position by a laser navigation mode; acquiring an image collected by a visual sensor; analyzing the image and acquiring ID information of the two-dimensional code in the image and calculating accurate pose of the carrier; judging the operation mode of the next stage, and controlling movement of the carrier according to the operation mode of next stage. The integrated navigation method with fusion of laser radar and two-dimensional code, the device and the system disclosed by the invention have the beneficial effects that the advantages of two navigation modes such as laser navigation and two-dimensional code navigation are integrated, the laser navigation can grasp the rough path, the two-dimensional code can provide position information, is used as a reference of position correction, and only needs to be arranged at a key part in a navigation area, and the visual sensor is arranged on the carrier, so that the cost of modification and maintenance is low.

Description

technical field [0001] The invention relates to the field of robot technology, in particular to a composite navigation method, device and system that integrates laser radar and two-dimensional code. Background technique [0002] At present, in the field of industrial production and life, various types of navigation devices such as autonomous navigation robots and autonomous navigation AGVs are becoming more and more common, and they are very popular because of their characteristics that can greatly improve production efficiency. [0003] Navigation technology is one of the most important core technologies of navigation devices such as autonomous navigation robots and autonomous navigation AGVs. Robots used to perform tasks in existing industries generally use laser radar as the core to navigate or two-dimensional codes as the core to navigate, and the relevant navigation technology is relatively mature. Laser navigation technology has many advantages, but its navigation acc...
