Claim Text:
1. A position determining method for continuously determining the spatial position of an auxiliary measuring instrument having at least one auxiliary point marking, wherein the auxiliary measuring instrument has a plurality of auxiliary point markings in fixed known spatial distribution relative to one another, comprising: continuously detecting camera images of the at least one auxiliary point marking using a camera with an area sensor having a plurality of pixels; continuously carrying out read-out passes in which at least some of the pixels are read out with regard to a respective current exposure value; continuously determining at least one image position for the at least one imaged auxiliary point marking in the respective current camera image, depending on exposure values obtained in the context of the respective current read-out pass; and continuously deriving the respective current spatial position of the auxiliary measuring instrument on the basis of the at least one current image position, wherein:
