    Projectors: Advanced Geometric Issues in Applications


    General knowledge of basic computer graphics theory and practice, including perspective projection and rendering. Also helpful: familiarity with video projection and basic concepts in computer vision. The primary intended audiences are designers and programmers who use or build applications for innovative projector-based systems.

    Calibration and projective geometry: pin-hole projector model, homography, curved transfer, global consistency, estimating pose, radial distortion, depth extraction. Image warping: rendering techniques, exploiting graphics hardware, intensity blending functions. Parametric and non-parametric approaches. Integration of camera, tracker, mirrors. Applications: casually aligned displays, spatially augmented reality, shadow removal.

    The latest computer vision and graphics techniques for projector-based displays. In addition to design, rendering, and calibration algorithms in conventional projector-based systems, this course provides a practical guide to relevant topics in image warping, projective geometry, transfer functions for curved screens, camera-assisted methods, and projector-based augmented reality.
