System for adjusting gap step and method of operating same

A system for adjusting a gap step, the system comprising:

• a process device configured to mount a first moving part and a second moving part;
• a first information obtaining device comprising a camera;
• and
• a control device configured to:
• control the process device based on a first driving control value such that the first moving part and the second moving part are mounted on a first vehicle body;
• obtain a first image of the first vehicle body on which the first moving part and the second moving part are mounted;
• obtain the gap step for the first moving part, the second moving part, or both, based on the first image;
• mount the first moving part and the second moving part on a second vehicle body by controlling the process device based on a second driving control value corresponding to the gap step;
• calculate a first measurement value for the first moving part and the second moving part through image analysis;
• convert depth information about the first vehicle body into plane information, when calculating the first measurement value;
• obtain the second driving control value for the process device based on the first measurement value;
• and
• calculate a second measurement value for the first moving part and the second moving part through image analysis,
• wherein:
• the first measurement value corresponds to a gap step difference generated between the first moving part and the second moving part mounted on the first vehicle body,
• the second measurement value corresponds to the gap step difference corrected by the second driving control value,
• the first vehicle body is a vehicle body before being introduced into a painting process after the first moving part and the second moving part are mounted through a vehicle body assembly process, and
• the second vehicle body is the vehicle body that is introduced into the process device controlled based on the second driving control value.
