Embedded high-speed on-line machine vision detection method and device

Abstract

The invention discloses an embedded high-speed online machine vision detection method, which comprises the steps of: acquiring the image signal of the measured object in the product line at high speed in real time; analyzing the acquired image of the measured object, separating and positioning the sensitive image area of easily appearing quality problem; picking up the characteristics of the sensitive image area of easily appearing quality problem; and the characteristics of the acquired sensitive image area are compared with the standard characteristics of the sensitive image area, and the measured object is estimated to be eligible or not according to that whether the similarity between two arrives the predicted value. In addition, the invention also discloses an embedded high-speed online machine vision detection device. Through the implementation of the invention, the production in the automatic production line can be detected at high speed, and the cost is low, which is conducive to the promotion and applications of wide range.

Description

technical field [0001] The invention relates to the technical field of automatic production, in particular to an embedded high-speed online machine vision detection method and device, which are mainly used in high-speed online quality detection in the automatic production process. Background technique [0002] With the rapid development of my country's economy, the Chinese government has incorporated the improvement of product quality into the national economic and social development plan, and ensuring product quality has become an important matter that every enterprise needs to pay attention to in the production work. [0003] At present, quality inspection in the automated production process is a key link to ensure product quality and a key link to improve the market competitiveness of similar products of an enterprise, and machine vision high-speed online inspection is the preferred solution to this problem. In the past, due to the limitation of hardware level and softwar...

AI Technical Summary

Problems solved by technology

In the past, due to the limitation of hardware level and software algorithm, the domestic machine vision online detection technology stayed at a low technical level, and its main implementation method is a desktop computer or industrial computer plus an image acquisition board, which is not only large in size, but also low in detection speed , far from meeting the requirements of high-speed real-time detection of enterprises

Although some foreign countries are relatively mature in the field of machine vision high-speed online inspection technology, the price of importing a set of machine vision equipment from abroad is very expensive.
