Abstract: The invention relates to an apparatus (1) for projection of a specified pattern (17) onto an installation surface (15) whose geometry is previously known, which comprises a laser projector (2) for projection of the pattern (17) onto the installation surface (15), a separate laser distance measurement device (3) based on the principle of the running time measurement of a diffusely reflected laser beam (6), which is connected with the laser projector (2), in a fixed position, whereby the exit direction of the laser beam (6) that leaves the laser distance measurement device (3) is specified in fixed and non-adjustable manner, a drive unit by means of which the laser projector (2) and the laser distance measurement device (3) can jointly be pivoted or rotated about two different axes (N, M), into an angle position that can be specifically specified, and at least one data processing device for controlling the laser projector (2), the laser distance measurement device (3), and the drive unit, in which the laser dis

Abstract: In a method for 3-dimensional measurement of the surface of an object, the object is imaged 2-dimensionally, at a first focal distance of at least one CCD camera (3, 30), which can be swiveled in two directions and which is provided with an optical zoom function, and at least one point (P1, P2) to be measured is selected on the surface of the object, onto which point the laser beam (L) is directed. The optical axis of the at least one CCD camera (3, 30) is aligned in zoom mode at long focal distance toward the light spot generated by the laser beam. The coordinates of the selected point are ascertained by using the direction vectors, determined by appropriate rotary position sensors, of the laser beam and of the optical axis of a CCD camera or by using the direction vectors of the optical axes of two CCD cameras aligned toward the light spot.
