A machine learning system in the present disclosure includes: an image pickup unit that photographs a product and acquires a product image; a preprocessing unit that generates an inspection target site image by clipping an image of an inspection target site of the product based on a setting file, and saves the generated inspection target site image in an image saving unit; and an inspection processing unit that performs a quality determination process on the inspection target site image of a quality determination object indicated as a quality determination target by production instruction information, in which when the inspection target site image saved in the image saving unit is relevant to a product that is designated by the production instruction information as a learning object that is not the quality determination target, the inspection target site image is accumulated in the image saving unit, as learning data.

Machine learning system, learning data collection method and storage medium

An inspection device includes: a captured image acquisition unit configured to acquire a captured image obtained by capturing an image of an inspection target; an image division unit configured to divide the captured image which is acquired into a plurality of first division images; a first composite image generation unit configured to superimpose the plurality of first division images to generate a composite image; and a determination unit configured to use the generated composite image and a learning model to determine whether or not a defect is present in the inspection target.

Inspection device, inspection method and program

A color tone correction system includes a reception unit that receives a target workpiece image and design information of a target workpiece, a reference image data storage unit that stores a reference workpiece image, an image determination unit that determines whether or not the target workpiece is inclined more than the reference workpiece, a calculation processing unit that estimates an inclination angle of the target workpiece based on the stored reference workpiece image and the target workpiece image, a color tone data storage unit that stores a relationship between the inclination angle and a color tone correction value, an image correction unit that corrects a color tone of the target workpiece image based on the estimated inclination angle and a color tone correction formula corresponding to the stored relationship, and an output unit that outputs the corrected target workpiece image.
