The application of 3D laser projection positioning in the guidance of defects in automotive paint is mainly reflected in the following aspects:

1. Defect detection and localization

By using a high-precision visual inspection system, it can quickly identify subtle flaws on the surface of the vehicle, such as scratches, particles, orange peel patterns, etc.

The system automatically records the location of defects and generates three-dimensional coordinate data.

2. Visual tagging

Real time projection of the located defect position onto the surface of the vehicle body through laser projection, forming clear and visible light spots or graphics.

Workers can directly perform precise repairs based on the projected markers without the need for manual measurement or recording.

3. Improve repair efficiency

Reduce the subjectivity and missed detection rate of manual visual inspection to ensure the accuracy of repair positions.

Support multi station collaborative work to shorten the processing time of a single vehicle.

4. Quality traceability

The system can synchronously record defect data and repair process, facilitating subsequent quality analysis and process optimization.

Technical advantages: Non contact detection avoids secondary damage, and millimeter level positioning accuracy significantly improves the standardization of paint repair.
