Embodiment 1

[0030] refer to figure 1 , a specific embodiment of the present invention includes

[0031] The first camera 1 is used to take pictures of the object to be measured;

[0032] The first light source 2 is located on the first camera 1, and the irradiation direction of the first light source 2 is parallel to the photographing direction of the first camera 1;

[0033] The second camera 3 is used to take pictures of the object to be measured, and the included angle between the second camera 3 and the first camera 1 is 45°;

[0034] The second light source 4 is located on the second camera 3, and the irradiation direction of the second light source 4 is parallel to the photographing direction of the second camera 3;

[0035] The controller 5 is connected in communication with the first camera 1, the second camera 3, the first light source 2 and the second light source 4, and is used to control the process of supplementing light and taking pictures, and to detect the pictures taken...

Embodiment 2

[0050] This embodiment is improved on the basis of Embodiment 1. When taking the first picture, the second picture and the third picture, the light source is irradiated with at least three luminances, and the same number of pictures are taken correspondingly; in step D, the same pictures under different luminances are first superimposed to form a After the image is drawn, the feature area is delineated. In addition, turn on both the first light source 2 and the second light source 4, use the first camera 1 to take pictures of the object to be tested, obtain the fourth picture, calculate the correlation degree between the fourth picture and the corresponding feature area of ​​the third picture, and then use this correlation The degree of linear correlation used to judge whether the object under test is consistent with the reference standard picture in step E is corrected,

[0051]

[0052] Among them, r 0 is the linear correlation in step E before correction, r' 0 is the ...

Abstract

The invention discloses an improved machine vision detection system, which comprises a first camera for taking a photo of a to-be-detected object, a first light source positioned on the first camera, a second camera for taking a photo of a to-be-detected object, a second light source positioned on the second camera, and a controller in communication connection with the first camera, the second camera, the first light source and the second light source. The irradiation direction of the first light source is parallel to the photo taking direction of the first camera, the included angle of the photo taking directions of the second camera and the first camera is 45 degrees, the irradiation direction of the second light source is parallel to the photo taking direction of the second camera, and the controller is used for controlling the process of fill light photo taking, and testing the taken photo. The invention also discloses a detection method of the improved machine vision detection system. The improved machine vision detection system and the detection method disclosed by the invention can overcome the shortcomings of the prior art, and the adaptability to different types of products can be improved.

Description

technical field [0001] The invention relates to the technical field of machine vision recognition, in particular to an improved machine vision detection system and a detection method thereof. Background technique [0002] Machine vision recognition has become a commonly used testing equipment for automated production lines. Existing machine vision inspection equipment is usually designed for characteristic products and has poor versatility. As a result, the machine vision inspection equipment needs to be updated synchronously after the product type is changed in the production line. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an improved machine vision detection system and its detection method, which can solve the deficiencies of the prior art and improve the adaptability to different types of products. [0004] In order to solve the above technical problems, the technical solutions adopted by the present in...
