• Title: Calibration of 3D Single-pixel Imaging Systems with a Calibration Field
• Authors: Xinyue Ma, Chenxing Wang,
• Abstract summary: 3D single-pixel imaging (SPI) is a promising imaging technique that can be ffexibly applied to various wavebands. The main challenge in 3D SPI is that the calibration requires a large number of standard points as references. In our work, we construct a Field (CaliF) to generate the standard points from one single image.

• Abstract: 3D single-pixel imaging (SPI) is a promising imaging technique that can be ffexibly applied to various wavebands. The main challenge in 3D SPI is that the calibration usually requires a large number of standard points as references, which are tricky to capture using single-pixel detectors. Conventional solutions involve sophisticated device deployment and cumbersome operations, resulting in hundreds of images needed for calibration. In our work, we construct a Calibration Field (CaliF) to efffciently generate the standard points from one single image. A high accuracy of the CaliF is guaranteed by the technique of deep learning and digital twin. We perform experiments with our new method to verify its validity and accuracy. We believe our work holds great potential in 3D SPI systems or even general imaging systems.

• Enhancing Soccer Camera Calibration Through Keypoint Exploitation [0.0]
  This paper introduces a multi-stage pipeline that addresses the challenge of obtaining a sufficient number of high-quality point pairs. Our approach significantly increases the number of usable points for calibration by exploiting line-line and line-conic intersections, points on the conics, and other geometric features. We evaluated our approach on the largest football broadcast camera calibration dataset available, and secured the top position in the SoccerNet Camera Challenge 2023.

  This paper introduces a novel camera calibration method using a collimator system. Based on the optical geometry of the collimator system, we prove that the relative motion between the target and camera conforms to the spherical motion model. A closed-form solver for multiple views and a minimal solver for two views are proposed for camera calibration.

  Existing methods for capturing datasets of 3D heads in dense semantic correspondence are slow. We introduce TEMPEH to directly infer 3D heads in dense correspondence from calibrated multi-view images. Predicting one head takes about 0.3 seconds with a median reconstruction error of 0.26 mm, 64% lower than the current state-of-the-art.

We conduct a large-scale human perception study where we ask participants to judge the realism of 3D objects composited with correct and biased camera calibration parameters.
