The invention relates to a dental camera (1) for at least one light source (4) for emitting an illumination beam (5), at least one projection means (9) for producing a projection pattern (30, focal having length a sharp focal plane (8) (7) focusing optics (6) for displaying a projected pattern (30, 40), the projection pattern projected on the object (2) (30, 40 ) Is reflected by the object (2) as an observation beam (10) and is acquired using a sensor (11), and to a camera (1) for 3D measurement of a dental object (2). In the measurement of the object (2), focusing optics (6), the camera (1) scanning position the focal length of the sharp focal plane (7) (8) is a defined plurality for (12,13,14,54 ) it is controlled so as to be progressively changes between the first image (35) and at least one second image (36) each scan position for (12,13,14,54) sensors (11 ), The sensor (11) or the projection means (9) moves back and forth so as to swing laterally with respect to the beam path of the observation beam and the first image (35) is detected by the sensor (11 ) And the second image (36) is acquired at the second sensor position (19) of the sensor (11), and during the swing movement the sensor (11) is acquired at the first sensor position (18) ) Of the sensor (11) (20) parallel to the row of sensor pixels by a distance (20) between a first sensor position (18) and a second sensor position (19) corresponding to the width of the first sensor axis Or along a second sensor axis parallel to the row of sensor pixels, or a first image (35) is acquired at a first position of the projection means (9), and a second image (36) is acquired in the second position of the projection means (9) during the swinging movement, the projection means (9), the first sensor axis projected pattern (30, 40) is parallel to the line (7) of the sensor (11) by the width of the pixels (33, 34) of the sensor (11) along a second sensor axis along or parallel to the rows 20).
