The invention relates to a method for measuring the attitude and/or position of objects by means of image processing methods. In this case, the self-shading caused by a defined non-planar calibration element ( 3 ) is determined in a calibration process image and parameters ( 8 ) are then determined for correcting shadows with the aid of the self-shading detected. In this case, at least one object to be measured is introduced into the area of coverage of a camera ( 1 ) and into the area irradiated by lighting ( 2 ), in order to produce a picture of the object for the purpose of measuring the attitude and/or position. The picture of the object is subsequently corrected by means of the specific parameters ( 8 ), and the attitude and/or position of the object are/is determined therefrom. It is therefore possible with the aid of the invention to measure the attitude and/or position of objects in space reliably by using a single picture and the self-shading of a known calibration element ( 3 ). The distorted shadow boundaries, produced by the lighting ( 2 ), of the object to be measured can be determined uniquely with the aid of the method. |
