A measuring device for triangulation measurement comprises a light transmitter for emitting illuminating light; a transmitting optical system, which directs the illuminating light in a plurality of light strips to an object; a light receiver for generating a measurement image of the object by measuring of light thrown back from illuminated object areas; and an evaluation unit for determining form or position information of the object based on the measurement image. According to the invention, for the assignment of which area in the measurement image belongs to which light strip, the transmitting optical system is designed so that it directs the illuminating light in differently formed light strips to the object. In addition a corresponding method for triangulation measurement is described.

Measuring device and method for triangulation measurement

A measuring device for triangulation measurement comprises a light transmitter for emitting illuminating light; a transmitting optical system for directing the illuminating light in a light pattern in the direction of an object; a light receiver for recording an image; a control and evaluation unit, which determines, in a measurement mode, form or position information of the object based on a measurement image of the light receiver. According to the invention the control and evaluation unit can change over between the measurement mode and a data reading mode, wherein the control and evaluation unit, in the data reading mode, evaluates the image with respect to encoded parameter data, and, in a subsequent measurement mode, uses the parameter data read in this way. In addition, a corresponding method for triangulation measurement is described.
