Method and system for shape recognition of recycler packaging based on infrared grating detection

Abstract

The invention provides a recycling machine package shape recognition method and a system based on infrared grating detection. A network service platform comprises a platform network communication module, a package shape feature configuration file generation module, a recycling machine configuration module and a platform alarming module. A recycling machine terminal module comprises an infrared grating state detection module, a package identification module, a package input and rebate module, a terminal alarming detection module, a terminal network communication module and a terminal maintenance management module. An infrared grating acquisition system comprises a DC motor, a belt conveyor, an infrared grating acquisition module and an infrared grating communication module. The method and the system provided in the invention have the advantages that the infrared grating device is adopted for detection on the shape and the size of the package, and the sensitivity and the precision are high; the infrared grating device is not easily influenced by illumination factors, the stability is high, the service life is long, and the maintenance cost is low; and the feature extraction algorithm of the invention has strong robustness and fault tolerance for noise.

Description

technical field [0001] The invention belongs to the technical field of intelligent identification terminals and resource recycling, and in particular relates to a method and system for recognizing the shape of packaging objects of recycling machines based on infrared grating detection. Background technique [0002] Since the United Nations Climate Change Conference in Copenhagen, addressing climate change has become the focus of international politics, mainly focusing on issues such as emission reduction targets, carbon tax, capital and technical cooperation. As a large developing country with high economic growth, China needs to respond to the high emission reduction targets proposed by developed countries on the one hand, and maintain rapid economic growth on the other hand. In order to achieve the "carbon emission reduction target" and strive for the "carbon emission right to speak", the Chinese government has started various tasks in terms of legislation, mobilization, a...

Problems solved by technology

The system has the following deficiencies: image acquisition has high requirements on camera, light source and working conditions, and the production and maintenance costs are high; the image processing part needs to be equipped with a high-performance processor to meet the real-time requirements; Noise can easily affect imaging, resulting in poor system robustness; packaging usually has differences such as deformation and loss of evaluation, and the corresponding images have different features such as contours and colors, making it difficult to maintain a high recognition rate
