Problems solved by technology

However, magnetic navigation is complicated to install on the ground, with a large workload, low flexibility and accuracy, and cannot meet the needs of complex paths; laser navigation does not need to lead to the route, but requires a relatively open path to realize navigation. For storage systems The occlusion of objects will affect the navigation accuracy; the visual navigation operation is relatively simple, but it is difficult to accurately locate the position

Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0038] Such as figure 1 As shown, the actual test warehouse setting of this RFID and vision-based information fusion positioning system: lay a 20mm wide red path marking line on the ground of the test warehouse, and install an RFID tag every 2m on the path line. This system uses passive passive tags.

[0039] Such as figure 2 , image 3 As shown, the hardware structure of the RFID and vision-based information fusion positioning system includes: RFID positioning unit, CMOS image acquisition unit and information processing unit. The RFID positioning unit includes an RFID reader 2 and an RFID tag; the CMOS image acquisition unit includes a CMOS camera 1 and a lighting circuit 2; the information processing unit includes a DM642 processing chip, a serial communication interface and a DSP core processing chip.

[0040] In the inventive system, both the CM...

Abstract

The invention discloses an information fusion positioning system and method based on RFID (radio frequency identification) and vision. The information fusion positioning system acquires route information by a camera mounted at the bottom of a mobile robot when executing warehousing and transporting tasks, acquires key point information via an RFID radio-frequency device at the bottom of the robot, cuts images on the basis of colors, converts the color space into YCbCr from RGB, and segmenting thresholds of the red chromacity component; a processor inspects whether a running route of the robot is correct or not according to the cut images and positioning signals read by an RFID reader-writer and navigates and controls motion of the mobile robot, so that the mobile robot can be correctly, quickly and stably navigated automatically, cannot get lost and collide with other obstacles and can arrive at destinations smoothly.

Description

technical field [0001] The invention relates to an information fusion positioning system and method based on RFID and vision. Background technique [0002] The characteristic of the intelligent warehousing system is that the logistics transportation in the warehouse does not require or only requires a small amount of manpower, and most of the transportation operations are completed by robots, so that the robot plays the role of logistics transfer in the intelligent warehousing system; the robot is in the process of carrying out the delivery of goods How to accurately identify the path and locate the key path points has become a key technology. [0003] At present, the commonly used methods include magnetic navigation, laser navigation, visual navigation, etc., but problems such as accuracy, stability, non-bias, and real-time performance still need to be solved urgently. However, magnetic navigation is complicated to install on the ground, with a large workload, low flexibil...
