Intelligent logistics sorting system based on infrared imaging image recognition and sorting method thereof

Abstract

The invention discloses an intelligent logistics sorting system based on infrared imaging image recognition. The intelligent logistics sorting system comprises a feeding conveying roller mechanism, overturning unloading mechanisms, discharging conveying mechanisms, magnetic induction labels and sorting recognition mechanisms. Each magnetic induction label comprises a label base body, an induction coil, a heating resistor and two electricity conducting layers, wherein the induction coil is provided with a plurality of circular points at intervals, the diameters of the circular points are different, the number of turns of the induction coil corresponds to the logistics information of the circulating box, and the arrangement sequence of the circular points corresponds to the logistics information of the circulating box. and the resistance values of the heating resistors of the magnetic induction label are equal. Each sorting recognition mechanism comprises a visible light camera, an infrared camera, an ultrasonic sensor, a magnetic field generating plate and a control unit. By the adoption of the intelligent logistics sorting system based on infrared imaging image recognition, the intelligent sorting operation of the circulating boxes can still be achieved under the imaging conditions of poor ambient light and poor label flatness, the intelligent logistics sorting system is suitable for sorting operation of the circulating boxes made of various materials, the use cost of the magnetic induction labels is lower, the large-batch requirement of logistics is met, and the intelligent logistics sorting system based on infrared imaging image recognition is suitable for large-scale application and popularization.

Description

technical field [0001] The invention relates to an intelligent logistics sorting system based on infrared imaging image recognition. Background technique [0002] At present, the sorting of logistics boxes is based on the information identification of logistics labels. For ordinary labels, the existing identification technology mainly reads the label information through image recognition technology, but in the process of shooting and imaging, the ambient light and the flatness of the label The imaging conditions such as high temperature are relatively strict, and the reading effect of the label information attached to the soft package is not good. [0003] Although the existing method of using RFID tags can effectively avoid the dependence of image recognition methods on imaging conditions, the existing RFID tags require radio frequency transmitting chips, which makes the production cost of RFID tags high, and is not suitable for occasions with large logistics requirements. ...
