1. A method for capturing a relative position of at least one first spatial point by means of a portable distance measuring device, the method comprising: positioning a known three-dimensional reference object in a capture zone of an image sensor of the portable distance measuring device and spaced away from the first spatial point, said known three-dimensional reference object having known features configured to be captured by optical means and are designed for a resection, wherein the features are arranged as a multiplicity of differently formed or patterned surfaces of the three-dimensional reference object; at least one first measuring process, comprising: measuring a first distance to the first spatial point, and recording a first reference image linked in time with measuring the first distance, the reference object being at least partly imaged in the first reference image; and ascertaining, using image evaluation and resection, the position and orientation of the distance measuring device relative to the reference object comprising: identifying the reference object; recalling stored information about known features of the identified reference object; and identifying positions of known features of the reference object in the first reference image.
