Method and camera for the three-dimensional measurement of a dental object

A camera for the three-dimensional measurement of a dental object, comprising:

• at least one light source, which emits an illumination beam,
• at least one projection means, which produces a projection pattern, and
• focusing optics, which display the projection pattern in a plane of sharp focus at a defined focal distance relative to the camera,
• wherein the projection pattern projected onto the object is reflected by the object as an observation beam and acquired by means of a sensor,
• wherein, during the measurement of the object, the focusing optics is controlled so that the focal distance of the plane of sharp focus relative to the camera is varied incrementally between a plurality of defined scan positions,
• wherein a first image and at least one second image are taken by means of the sensor for each scan position,
• wherein the sensor is configured to be moved back and forth in an oscillating manner laterally to the beam path of the observation beam,
• wherein the first image is acquired in a first sensor position of the sensor and the second image is acquired in a second sensor position of the sensor.
