AI Technical Summary

Technical Problem

Existing welcome projection systems have shortcomings in terms of interactive effects and projection adaptability. In particular, they are difficult to achieve accurate projection on uneven surfaces. Furthermore, traditional solutions are costly, have low integration, and are difficult to adapt to complex environments.

Method used

The system uses a structured light sensing module to acquire depth images of the projection surface and object images. Combined with projection modeling and object recognition modules, it constructs the change relationship. The image anti-distortion processing module performs pre-transformation processing to generate an anti-distortion image and project it in real time, achieving high-precision interactive projection.

Benefits of technology

It significantly improves the interactive experience and projection effect, enables precise projection on uneven surfaces, reduces costs and increases integration, and supports real-time interactive control of user actions.
