Abstract: The invention relates to a method for the safe detection and position determination of objects by means of an optoelectronic scanner. In this method an external reference target is provided in the field of vision and the actual signal level of the reflections from the reference target is detected. A desired degree of reflection of the reference target is calculated from the measured distance from the reference target, from a scanner-specific distance-dependent reception characteristic of the light receiver and from the currently measured received signal on the reference target. Since the degree of reflection of the reference target is not fixedly predefined and is e.g. not taught, but is rather fixed by the aforesaid calculation on the putting into operation, the safety apparatus in accordance with the invention has an exactly defined detection capability even if soft targets such as fog, rain, snow or other air pollution are present.
