Alignment system

A method for adjusting a medical stereoscopic optical system comprising:

• arranging a predetermined reference object having known visible reference object features in a field of view captured by the optical system;
• capturing a first and a second stereoscopic half-image of the predetermined reference object by means of a sensor system;
• determining position information of at least two visible reference object features of the predetermined reference object that are imaged in the first and the second stereoscopic half-images;
• ascertaining an optical distortion of the first and the second stereoscopic half-images from the position information of the at least two visible reference object features;
• adjusting an image processor, which is at least indirectly connected to the sensor system, by setting a geometric rectification in a manner corresponding to the optical distortion ascertained;
• wherein, after said adjusting the image processor the method then comprises repeatedly carrying out the following steps during operation of the optical system for capturing an object to be examined:
• arranging the object to be examined in the field of view captured by the optical system;
• capturing position data containing a position deviation determined by means of at least one reference point of the first and the second stereoscopic half-images provided by the optical system of the object to be examined relative to each other, wherein said position deviation is a deviation of an image position of said object to be examined with respect to an ideal position of said object in a completely centered optical system;
• and
• adjusting the image processor in a manner corresponding to the captured position deviation between the first and second stereoscopic half-images by setting a corresponding displacement of the first and the second stereoscopic half-images by means of the image processor to perform a correction between the mutual position of the first and second stereoscopic half-images among one another.
