Problems solved by technology

[0003]In the existing production line, for the detection of the data line interface, the machine can only detect the performance of the data line interface, and the wear, loss, discoloration, etc. of the data line interface The appearance problem can only be detected manually. How to use visual inspection technology to improve the detection efficiency of the data line interface is a problem that we need to solve. Now we provide an automatic detection method for the data line interface based on machine vision.

Embodiment Construction

[0032] like figure 1 As shown, a method for automatic detection of a data line interface based on machine vision includes the following steps:

[0033] Step 1: Set the visual inspection area, and locate the data line interface in the visual inspection area;

[0034] Step 2: Obtain the visual image of the data line interface after the positioning is completed through the visual acquisition device;

[0035] Step 3: Process the acquired visual image, and detect and analyze the data line interface according to the processed visual image;

[0036] Step 4: Mark the abnormal points according to the analysis results, and remove the abnormal data line interface at the same time.

[0037] It should be further explained that, in the specific implementation process, the setting process of the visual detection area specifically includes:

[0038] Construct a polygon area as the detection area of ​​the data line interface, and set several positioning points in the polygon area;

[0039]...

Abstract

The invention discloses a data line interface automatic detection method based on machine vision, and relates to the technical field of visual detection, a data line interface is placed in a specified detection area, a visual device locates and identifies the data line interface, and then each feature of the data line interface is analyzed; according to the data line interface detection method, the condition of each feature of the data line interface is rapidly judged, and when any feature is abnormal, the data line interface is marked and removed, so that each data line interface is ensured to be a qualified product, and the production detection efficiency of a production line is improved; by processing the visual image acquired by the visual equipment, the position of the data line interface in the visual image acquired by the visual equipment can be more suitable for standardization, so that the situation that the identification effect of the data line interface is influenced due to posture difference when the data line interface enters a detection area is avoided, and the detection accuracy is improved. The compatibility and error correction of visual identification are enhanced, so that the visual identification effect is greatly improved.

Description

technical field [0001] The invention relates to the technical field of visual detection, in particular to an automatic detection method of a data line interface based on machine vision. Background technique [0002] Machine vision technology is an interdisciplinary subject involving artificial intelligence, neurobiology, psychophysics, computer science, image processing, pattern recognition and many other fields. Machine vision mainly uses computers to simulate human visual functions, extract information from images of objective things, process and understand them, and finally use them for actual detection, measurement and control. [0003] In the existing production line, for the detection of the data line interface, the machine can only detect the performance of the data line interface, and for the appearance problems such as wear, loss and discoloration of the data line interface, it can only be detected manually. How to use visual inspection? It is a problem that we nee...
