Abstract (en)
[origin: WO2009003692A1] An apparatus for imaging the inner surface (4) of a cavity, which is preferably cylindrical, in a workpiece (8) has an optical system (2) with a panoramic view of preferably 360°, means for advancing the optical system (2) perpendicular to the plane of the panoramic view, a digital image sensor (10) with a planar image pick-up area on which the panoramic image recorded by the optical system (2) is imaged, and means which use the digital output signals from the image sensor (10) to generate a Cartesian image which is a development (40) of the inner surface of the cavity. According to the invention, the digital image sensor (10) is designed in such a manner that only output signals are generated in accordance with an annular band on the inner surface of the cavity on a plane essentially transverse to the direction in which the optical system is gradually advanced, wherein these output signals form the image contents of the lines of an overall Cartesian image.
