ACCURATE CAMERA-DISPLAY CALIBRATION FOR TELEPRESENCE VIDEOCONFERENCING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240338851 titled 'ACCURATE CAMERA-DISPLAY CALIBRATION FOR TELEPRESENCE VIDEOCONFERENCING
- Simplified Explanation:**
The patent application discusses techniques for calibrating telepresence videoconferencing displays and cameras using fiducial markers on a mirror and a checkerboard pattern on the display.
- Key Features and Innovation:**
- Providing 6 degrees of freedom camera locations and orientation vectors in the display reference frame. - Using a plurality of images to determine specified mirror-plane points and reflected display plane points. - Fiducial markers on the mirror indicate mirror-plane points, while a checkerboard pattern on the display indicates reflected display plane points.
- Potential Applications:**
- Telepresence videoconferencing systems - Virtual reality applications - Augmented reality technologies
- Problems Solved:**
- Ensuring accurate calibration of telepresence videoconferencing displays and cameras - Improving the overall quality and experience of videoconferencing sessions
- Benefits:**
- Enhanced video quality and accuracy - Improved user experience and immersion - Simplified calibration process
- Commercial Applications:**
Title: Advanced Calibration Techniques for Telepresence Videoconferencing Systems This technology can be used in telecommunication companies, virtual reality companies, and businesses that rely on videoconferencing for communication and collaboration.
- Questions about Telepresence Videoconferencing Calibration:**
1. How does the use of fiducial markers on the mirror and a checkerboard pattern on the display improve calibration accuracy? 2. What are the potential limitations of this calibration technique in different lighting conditions?
Original Abstract Submitted
techniques of calibrating telepresence videoconferencing displays and cameras include providing 6 dof camera locations and orientation vectors in display reference frame based on a plurality of images that indicate specified mirror-plane points of a mirror and specified reflected display plane points. in some implementations. the specified mirror-plane points are located at fiducial markers printed on the mirror. in some implementations. the specified reflected display plane points are located in a checkerboard pattern of fiducial markers on the display.
