The 3-D information obtained from cameras' 2D images is given as a visual line by using calibrated parameter values, and we should evaluate the calibration accouracy with respect to the visual line direction error. In this paper, the visual line direction error was examined, based on an evaluation criterion where the calibrated principal point coordinates are taken as the references of the visual line. Many important caracteristics with the calibrated parameter value errors and their resulting visual line direction errors were found out by conducting a large amount of simulations under various conditions such as the depth ratios of calibration chart, and the principal distances of cameras. Fnally, the error characteristics were analytically proved, and some formulae were derived. The formulae enable us to estimate calibration errors for any calibration conditions in advance.
