METHOD AND APPARATUS FOR CALIBRATING AN ELECTRONIC CAMERA

摘要

The invention relates to a method for calibrating an electronic camera or a sensor, in particular a line camera, in which a series of image points or pixels on the projection plane (P) of the camera can be associated with consecutive numbers and the measurement region which can be detected by the optics of the camera is divided by means of a calibrating part into bright/dark transitions with known spacing between each other, wherein each bright/dark transition is associated with a particular pixel number, the determined bright/dark transitions are evaluated as to which ones of the bright/dark transitions of possibly a plurality of planes are to be associated with an upper and which are to be associated with a lower plane of the calibrating part, and a calculation is carried out as to where a bright/dark transition on the lower plane is to be placed if only the bright/dark transition, which is located perpendicularly above it, on the upper plane can be seen due to skewed observation through the camera.
