Vision King – Paint Shop

Technology Description

The main objective is to perform precise detection of defects and imperfections in automotive paint and clear coat, ensuring the aesthetic and functional quality of vehicle surfaces:

Scratches

Lint trapped in the primer surface

Stains

Crater in the primer surface

Dirt

Dirt inclusion in the primer surface

Hairs

Hair trapped in the primer surface

Craters

Bump in the primer surface

The application of computer vision in automotive paint inspection has become an indispensable solution for ensuring quality in vehicle manufacturing processes. This technology plays a key role in preventing recalls and ensuring end-customer satisfaction by maintaining high aesthetic and functional standards. The Vision King system integrates high-resolution cameras and advanced image processing algorithms to detect, in real time, defects, inclusions, and dirt on newly painted surfaces — imperfections often imperceptible to the naked eye.
