AI Technical Summary

⚠Technical Problem

Existing lighting systems struggle with precise localization and individualization of objects under dynamic conditions, particularly when multiple objects overlap or move rapidly, leading to computational intensity and resolution limitations in distance images.

⚗Method used

A lighting system incorporating a distance measuring unit and a marker system, where the object is equipped with a marker emitter unit, allowing for precise localization and individualization by combining distance images with marker signals, reducing computational effort and enabling faster response times.

🎯Benefits of technology

The system achieves accurate localization and individualization of objects, simplifying decision-making processes and reducing computational complexity, even under dynamic conditions, by correlating distance images with marker signals, thus enhancing automation and reliability.
