1. A stereoscopic image recording method (34) for the positionally correct positioning of images of a stereoscopic image (29) during a rotation, comprising:
recording an image pair (40) by a stereoscopic endoscope (14);
said stereoscopic endoscope (14) being a side view endoscope, wherein a side view unit (19) is embodied at a distal end (18) of said side view endoscope (14) so that a viewing direction (20) of said stereoscopic endoscope (14) is angled relative to a longitudinal axis (21) of a shaft (15), wherein said stereoscopic endoscope (14) has an angle measuring device (22), said angle measuring device (22) being configured to detect an alignment angle (23) by which the stereoscopic endoscope (14) is rotated;
calculating depth information (13) from the image pair (40);
determining an alignment angle (23) by the angle measuring device (22), wherein the alignment angle (23) describes a position of the image pair (40) in relation to a preferred direction (30);
transforming the depth information (13) based on the alignment angle (23); using the transformed depth information (26) for calculating at least one transformed image pair (28); and
outputting the transformed image pair (28) as the stereoscopic image (29) so that a position of an image horizon in a stereoscopic image is maintained even during a rotation.
