AI Technical Summary

⚠Technical Problem

Existing projection technology cannot achieve dynamic calibration, resulting in poor user interaction, easily distorted and warped images, and poor stability, especially in complex wall environments.

⚗Method used

By acquiring the 3D point cloud data of the circular wall and the spatial pose information of the projector, a point cloud model is generated and calibrated. The projected image is mapped in real time, and dynamic calibration and minor compensation processing are performed in combination with user interaction data to achieve accurate projection of the projector.

Abstract

This application discloses a dynamic projection interaction calibration method and system for a circular sci-fi space, belonging to the field of projection interaction technology. The method includes: acquiring 3D point cloud data of the circular wall and spatial pose information of each projector; constructing a point cloud model of the wall and calibrating the projectors accordingly to obtain a pose parameter dataset. Based on this dataset, each frame pixel of a preset image sequence is mapped to the corresponding position on the wall in real time. If user interaction is detected, the interaction area is determined and corresponding logic is executed. During this process, projection feedback images are continuously acquired, and dynamic calibration and minor compensation are performed in conjunction with the pose parameters to generate calibrated projection coordinates and real-time interactive response data. Based on this, all projectors are controlled to complete real-time and stable projection display on the circular wall. This solution ensures that the projected image, the circular wall, and user operations are highly consistent, achieving dynamic calibration and real-time interaction, improving the display accuracy and stability of the projection, and enhancing the user's immersive experience.
