Embodiment Construction
[0042] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0043] Embodiments of the present invention provide an image self-correction method, device and storage device suitable for metal workpiece recognition.
[0044] Please refer to figure 1 , figure 1 It is a flow chart of an image self-correction method suitable for metal workpiece recognition in an embodiment of the present invention, specifically including the following steps:
[0045] S101: Use the camera to collect the first workpiece image, and use a Gaussian filtering method to filter and denoise the workpiece image to obtain a filtered second workpiece image;
[0046] S102: Calculate the average gray level of the second workpiece image
[0047] S103: judgment condition Whether it is established; if so, go to...

The invention provides an image self-calibration method, device and storage device suitable for metal workpiece identification. The method includes: using a camera to collect images of workpieces, judging the quality of the collected images, and performing image self-correction processing if unqualified. And according to the specific situation of the image quality, self-correction is divided into two ways: global correction and local correction, so as to improve the quality of the image; an image self-correction device and storage device suitable for metal workpiece recognition, used to realize metal Image self-correction method for workpiece recognition. The beneficial effects of the present invention are: the technical solution provided by the present invention can quickly self-correct the image when the image collected by the camera is unqualified, without manual intervention, low cost and strong practicability.
Description
technical field [0001] The invention relates to the field of machine vision, in particular to an image self-correction method, device and storage device suitable for metal workpiece recognition. Background technique [0002] At present, machine vision technology is widely used in all aspects of industrial sites. Usually on the assembly line, machine vision is often used to automatically detect defects or shapes of some metal workpieces. If the detected metal workpiece is located outdoors, the quality of the collected images is easily disturbed by the light intensity. Metal components under too dark lighting conditions are often unable to be recognized by machine vision technology; while metal components under too bright lighting conditions, there will be reflection problems, resulting in the texture or characteristics of the metal itself cannot be effectively displayed in the image middle. The use of image correction technology can effectively solve this problem. [0003...
