ScreenCalib permite a detecção de luz e o alcance (LiDAR) - calibração extrínseco da câmera usando uma exibição programável comum, fornecendo marcadores visuais conhecidos e geometria controlada, reduzindo a preparação do alvo dedicado. A câmera observa os marcadores de abril exibidos, enquanto o LiDAR mede a superfície física da tela e o limite, exigindo associação intermodal indireta. A geometria da exibição introduz ambiguidades de associação, enquanto a confusão interior complica a extração. ScreenCalib aborda esses desafios através da extração de tela guiada por tags, geração de hipóteses geométricas e refinamento

Abstract

ScreenCalib enables light detection and ranging (LiDAR)--camera extrinsic calibration using an ordinary programmable display, providing known visual markers and controlled geometry while reducing dedicated target preparation. The camera observes displayed AprilTags, whereas the LiDAR measures the physical screen surface and boundary, requiring indirect cross-modal association. Display geometry introduces association ambiguities, while indoor clutter complicates extraction. ScreenCalib addresses these challenges through tag-guided display extraction, geometric hypothesis generation and refineme
