Camera Calibration Error Analysis in Stereo Measurements
نویسندگان
چکیده
Camera calibration is an important and sensitive step in 3D environment reconstruction by stereovision. Small errors in the estimation of the camera parameters could rise to high errors in the 3D measurements, as the working distance increases. Therefore a method for analyzing the influence of each camera’s parameter error in the accuracy of the 3D measurement is compulsory in order to minimize the overall 3D reconstruction error. In this paper we propose a method to analyze the influence of each camera’s parameter of the stereovision system by applying a 3D stereo-reconstruction algorithm on a controlled 3D scene, having a depth range comparable with the working range of the 3D measurement application.

Camera Calibration Method for Stereo Measurements
Camera calibration is an important and sensitive step in 3D environment reconstruction by stereovision. Small errors in the initial estimation of the camera parameters (especially in the estimation of the principal point) could rise to high errors in the 3D measurements, which are increasing with the working distance. There are many general-purpose calibration methods for calibration of individ...
متن کاملE ects of Camera Alignment Errors on StereoscopicDepth
We present in this paper a new analysis of relative sensitivity/importance of camera calibra-tion/alignment parameters on the performance of stereoscopic depth reconstruction. For a given stereoscopic vision system, once stereo correspondence is successfully established, the accuracy of 3D measurements depends on the overall geometric structure of the model in relation to object distances. The ...
متن کاملAn empirical study on the effects of spatial discretization error in a stereo vision system
considered the case in which the images are in the same imaging plane and the optical axes of the two images are parallel. The triangulation error is inversely proportional to the product of baseline x focal length. At a given focal length, a wider baseline reduces triangulation error but increases both geometric and photometric distortions in images which in turn makes matching of these images...
متن کاملError Analysis and Design Considerations for Stereo Vision Systems Used to Analyze Animal Behavior
This paper presents an analysis of patterns of error in the triangulation of 3D points from stereo camera systems that are used in field work to study the behavior of bats in flight. A measure of the error present in a 3D reconstruction is proposed. A method for empirically testing the performance of a particular stereo camera configuration through a software simulation is presented. Randomly g...
متن کاملStereo Calibration from Rigid Motions
This paper describes a method to upgrade projective reconstruction to a ne and to metric reconstructions using rigid general or planar motions of a stereo rig. We make clear the algebraic relationships between projective reconstruction, the plane at in nity (a ne reconstruction), camera calibration, and metric reconstruction when a 3-D scene is observed with a moving stereo rig. Based on an in-...
