The invention discloses a method, device, equipment and storage medium for detecting the integrity of a segmented circular workpiece. The sampling point data of the original image of the workpiece to be detected is obtained, the sampling point data is initially fitted, and the initial The initial average center of each fitted circle obtained by fitting; the center of each fitted circle is removed according to the initial average center to obtain the initial center data; the initial center data are clustered, and according to the category data obtained by clustering The number of continuous sampling points, determine the target circle center information of the category data; calculate the target average center of each target circle center in the target circle center information, and calculate the distance from the circle center of the target category in the category data to the target average circle center Distance information: determining whether the workpiece to be detected is complete or not according to the distance information. The invention accurately detects the integrity of segmented circular workpieces in batches to be detected one by one, so as to eliminate unqualified workpieces and improve the overall quality of batched workpieces.
Description
technical field [0001] The invention relates to the technical field of detection, in particular to a method, device, equipment and storage medium for integrity detection of segmented circular workpieces. Background technique [0002] Many circular workpieces in the industry need to be segmented into different arcs and then assembled into a segmented circular workpiece. In this assembly process, the final segmented circular workpiece is not a perfect circle due to factors such as whether the arc parts are assembled in place. When the radius of the segmented circular workpiece is within the allowable tolerance range, it is considered a qualified product, otherwise it is a defective product. How to detect the integrity of the circle has always been a difficult problem in the industry. [0003] At present, the industry mainly adopts the method of manual sampling to detect the integrity of segmented circular workpieces. The manually detected products are first measured with a c...
