Method and device for generating image data for machine learning

An apparatus for generating image data for machine learning, the apparatus comprising:

• one or more processors;
• a network interface receiving 3D CAD data for a product and a site information;
• a memory loading a computer program executed by the processor;
• and
• a storage storing the computer program,
• wherein the computer program includes:
• an operation of extracting first image data for a product generated as a result of conducting a first step among a plurality of steps of the manufacturing process of a product based on the 3D CAD data;
• an operation of generating a plurality of posture conversion image sets corresponding to a plurality of postures for the product, respectively, based on the first image data;
• an operation of performing image processing through a rendering engine by applying actual image data to respective images of the plurality of posture conversion image sets;
• and
• an operation of generating a learning data set for the first image data through the image processing,
• wherein the operation of the performing the image processing through the rendering engine by applying the actual image data includes:
• receiving physical value information, environment value information, and noise information corresponding to the first step from an infrastructure network database storing the site information corresponding to the first step;
• and
• generating the actual image data based on the physical value information, the environment value information, and the noise information.
