Improving self-calibration.
Response calibration is the process of inferring how much the measured data depend on the signal one is interested in. It is essential for any quantitative signal estimation on the basis of the data. Here, we investigate self-calibration methods for linear signal measurements and linear dependence of the response on the calibration parameters. The common practice is to augment an external calib...
متن کاملCatadioptric Self-Calibration
We have assembled a standalone, movable system that can capture long sequences of omnidirectional images (up to 1,500 images at 6.7 Hz and a resolution of 1140 × 1030). The goal of this system is to reconstruct complex large environments, such as an entire floor of a building, from the captured images only. In this paper, we address the important issue of how to calibrate such a system. Our met...
متن کاملConstrained Self-Calibration
This paper focuses on the estimation of the intrinsic camera parameters and the trajectory of the camera from an image sequence. Intrinsic camera calibration and pose estimation are the prerequisites for many applications involving navigation tasks, scene reconstruction, and merging of virtual and real environments. Proposed and evaluated is a technical solution to decrease the sensitivity of s...
متن کاملRadiometric Self Calibration
A simple algorithm is described that computes the radiometric response function of an imaging system, from images of an arbitrar), scene taken using different exposures. The exposure is varied by changing either the aperture setting or the shutter speed. The algorithm does not require precise estimates of the exposures used. Rough estimates of the ratios of the exposures (e.g. Fnumber settings ...
متن کاملCamera Self-Calibration
Camera calibration is the problem of estimating a camera’s intrinsic parameters, which among others include the focal length and image center of the camera. The estimation of the camera’s intrinsic parameters is important as it is a prerequisite to a wide variety of vision tasks related to motion and stereo analysis. Historically, camera calibration was performed by knowledge of 3D world points...
