Precision & efficiency in automotive paint inspection

Precise detection of surface defects on automotive paint with the DM ES Hybrid Data Camera.

Background

With the widespread adoption of New Energy Vehicles (NEVs), consumer expectations for vehicle aesthetics and build quality have escalated. As the core of the user’s visual experience, the gloss and flatness of the paint finish are now critical factors in purchasing decisions.

However, traditional inspection methods face significant challenges, including efficiency bottlenecks, subjective human errors, and poor compatibility with complex materials.

Solution advantages

The 2.5D camera can precisely capture paint defects, delivering a major leap in both quality and efficiency for paint shops.

DM ES is the combination of HDC DM Series and screen light.

1. Highly flexible optical system

The triangular architecture allows for freely adjustable lighting angles, ensuring compatibility with gentle curves. It also supports collaboration with robotic arms to achieve multi-point coverage on complex curved surfaces.

2. High integration & versatility

Designed for flexibility, it pairs easily with various accessories to suit different Fields of View (FOV) and defect types. It is easy to deploy and reconfigure, making it ideal for integration with robotic automation.

3. Driven by powerful HWCI technology

Equipped with Mega Phase’s advanced built-in imaging algorithms and low-latency lighting synchronization, the camera delivers multi-channel image output and high-frame-rate acquisition.

Dense-information result

As mentioned above, the Hybrid Data Camera helps detect multiple paint defects in just a single shot. Typical defects and flaws captured and processed are as follows:

By adjusting parameters such as the period, direction, and style of the structured light patterns, the Hybrid Data Camera effectively captures defects like orange peel, dents, craters, and particles in just one shot.

This multi-channel data output capability makes it effortless to replicate across production lines and tuning. It adapts to different vehicle colors and models, significantly reducing deployment time while ensuring system stability and imaging consistency.
