WebCamera resectioning is the process of estimating the parameters of a pinhole camera model approximating the camera that produced a given photograph or video; it determines which incoming light ray is associated with each pixel on the resulting image. Basically, the process determines the pose of the pinhole camera. WebThe bar graph indicates the accuracy of the calibration. Each bar shows the mean reprojection error for the corresponding calibration image.
