Identification system

Abstract

The invention discloses an identification system which comprises an identification device and a conveying device. The identification device is fixedly arranged above the conveying device. The conveying device is used for conveying a to-be-identified object. The identification system is characterized in that the identification device comprises an image photographing device, an ultrasonic ranging device and an identification program. Through the imaging photographing device, the images of the to-be-identified object can be photographed continuously, and real-time analysis is performed for determining whether a tracking object which is similar with a preset target shape exists in the video images. In real-time tracking on the tracking object, object detection is performed simultaneously. Then a real-time tracking object is fused with the detected object, thereby improving identification precision. Furthermore judgment is performed on information which is measured by the image photographing device and the information that is measured by the ultrasonic ranging device, thereby improving judgment precision. The identification system is suitable for performing detection of specific labels and symbols on the to-be-identified object, thereby detecting whether the labels and symbols exist and are complete.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to an identification system. Background technique [0002] At present, in industrial production, the recognition of labels and characters mostly stays in triggering the camera to capture through the trigger, and then analyzes the captured single picture, and outputs the analysis result. This recognition method has strict requirements on the lighting environment, product material and label size, otherwise it will seriously affect the recognition accuracy. It is even more difficult to be compatible with products with both tiny tags and larger tags, and requires the use of larger and more expensive industrial computer PCs, which greatly limits the popularization of machine vision in industrial production. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a recognition system with high recognition accuracy. [0004] In ord...
