Problems solved by technology

Furthermore, when automatic optical inspection is used for product inspection on the production line, the image on the product becomes a dynamic image. Therefore, mechanical positioning, manual positioning, and comparison and positioning of pattern elements are required, which slows down the inspection speed and reduces the Productivity
Under the limitations of existing technology, problems such as large errors, frequent occurrence of offsets, and large workload of correction algorithms will easily occur, which will lead to reduced efficiency and positioning deviation, which will cause risks and errors in subsequent detection and identification. sentence

Abstract

The invention discloses an image information detecting method. The image information detecting method comprises the following steps: selecting a matched datum from a standard sample; capturing a continuous image of a to-be-detected sample; acquiring a plurality of frame to-be-detected images from the continuous image; selecting a character datum of each to-be-detected image; and comparing the matched datum with each character datum so as to obtain a matched rate. By utilizing the image information detecting method, the positioning precision can be improved so as to reduce the detection deviation.

Description

technical field [0001] The invention relates to a method for detecting image information. Background technique [0002] With the development of high-resolution, the improvement of process technology and the demand for automation in industrial production, the traditional manual visual inspection (Manual Visual Inspection, MVI) detection method has gradually become limited. Usually, it can only detect missing components, model classification, and some obvious mistakes. Because it is easily affected by human subjective and objective factors, it has high instability, difficulty and cost. Therefore, the invention of Automated Optical Inspection (AOI) equipment came into being. [0003] Automatic optical inspection is a detection method with considerable market potential in recent years. Its basic working principle is mainly to obtain the graphic information of the detected object through the image sensor, and then use the built-in computer software to process and calculate for ...
