Machine vision-based instant noodle seasoning packet automatic detection instrument and method

Abstract

The invention belongs to the technical field of automatic detection and relates to a machine vision-based instant noodle seasoning packet missing detection instrument, comprising a computer, at least one video camera, an image acquisition card, a light source, a position sensor and a controller, the position sensor is used for sensing the working beat of a packaging line; the video camera is used for acquiring color images, and the computer utilizes the controller to control the shooting rhythm of the video camera according to the input of the position sensor, analyzes areas of the images which are fallen into the set color thresholds for different seasoning packets according to the input color images and judging whether the corresponding seasoning packets are existed or not, so as to alarm or delete for the situations with packet missing. The invention simultaneously provides a detection method which is realized by utilizing the instrument. The invention completely overcomes the interferences of subjective factors in the artificial visual method and can rapidly, objectively and accurately detect the existence of the seasoning packets and the number integrity.

Description

technical field [0001] The invention belongs to the technical field of automatic detection, and in particular relates to a method and an instrument for detecting whether a material bag in an instant noodle package is missing. Background technique [0002] With the intensification of global economic integration, the food and drug industry has higher and higher requirements for product quality, forcing companies and enterprises in related industries to invest more human and financial resources in product quality inspection.

Problems solved by technology

The manual detection method is convenient, intuitive, and has high accuracy, but it is greatly affected by subjective factors, and the workers' work intensity is high. Long-term work is easy to cause visual fatigue, judgment errors, and affect product quality inspection; and when the packaging line speed is too fast , the operator is basically unable to complete the detection
