Tsai’s camera calibration method revisited
A calibration target can be imaged to provide correspondences between points in the image and points in space. It is, however, generally impractical to position the calibration target accurately with respect to the camera coordinate system using only mechanical means. As a result, the relationship between the target coordinate systemand the camera coordinate system typically also needs to be re...
متن کاملHRI: Four Lessons from Acting Method
This informal paper discusses four principles found throughout much of the acting method literature that may be of value to HumanRobot Interaction (HRI) design: (1) psycho-physical unity, (2) mutual responsiveness, (3) objective and inner monologue, and (4) the taking into account of circumstances. This work is founded on the notion that both acting and HRI design are concerned with physically ...
متن کاملCamera 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 کاملReverse-Projection Method for Measuring Camera MTF
This paper proposes several adjustments to the ISO 12233 slanted edge algorithm for estimating camera MTF. First, the Ridler-Calvard binary image segmentation method is used to find the line. Secondly, total least squares, rather than ordinary least squares, is used to compute the line parameters. Finally, the pixel values are projected in the reverse direction from the 1D array to the 2D image...
متن کاملCalibration Method for Misaligned Catadioptric Camera
This paper proposes a calibration method for catadioptric camera systems consisting of a surface of revolution mirror and a perspective camera, such as HyperOmni Vision. The proposed method is based on conventional camera calibration and mirror posture estimation. Many methods for camera calibration have been proposed. During the last decade, methods for catadioptric camera calibration have als...
