Vision King – Primer & E-coat

Technology Description

The main objective is to identify defects and imperfections on Class A surfaces, freshly painted with primer or e-coat, such as:

High Spot

Bump in the primer surface

Hair

Hair trapped in the primer surface

Dirt

Dirt inclusion in the primer surface

Crater

Crater in the primer surface

Lint

Lint trapped in the primer surface

Computer vision applied to the inspection of surfaces prepared with primer or e-coat has become a fundamental solution to ensure quality in vehicle manufacturing processes. It prevents defective surfaces from advancing along the production line or reaching the end customer. The Vision King system utilizes high-resolution cameras combined with advanced image processing algorithms to detect defects, irregularities, and specific surface characteristics that are difficult to identify with the naked eye.
