A method for generating and evaluating an image of a section of an object using an optical sensor. To generate a bright image, individual images are recorded of a section, of which individual images at least some individual images overlap at least in part in each case, and that to generate the image, the individual images or signals are aligned with respect to one another and superposed to form an overall image as the image of the at least one section, so that the evaluation of the overall image is substantially restricted to the overlapping regions of the individual images and/or the evaluation of the overall image or of a part thereof is brought about on the basis of the overlapping regions of the individual images having the latter. |

1. A method for generating and evaluating an image of at least one section of an measurement object, the method comprising:
providing a coordinate measurement apparatus with a multi-pixel camera, wherein the coordinate measurement apparatus is used which provides means for the relative movement between the measurement object and the camera, and into which the camera is integrated; wherein, of the at least one section, individual images deviating in their positions from one another are recorded in such way that at least several individual images in each case at least partially overlap in such manner that, for generating the image, the individual images, or signals thereof, are aligned with respect to one another, with respect to at least one section, and are superposed to form an overall image as the image of the at least one section, such image being greater than an individual image; wherein the spatial position of the individual images with respect to one another is determined with the aid of the camera position, determined for each individual recording, wherein the relative positions between the measurement object and camera are determined on the basis of the positions of the axes of the coordinate measurement apparatus, and the individual images are shifted with respect to one another in consideration of such relative positions, and are superimposed to form the overall image; wherein the evaluation of the overall image is substantially limited to the overlapping regions of the individual images, and/or the evaluation of the overall image, or of a portion thereof, occurs on the basis of the overlapping regions of the individual images comprising said regions, wherein the gray values of the overlapping sections are added for forming the overall image; and wherein object points and/or contours and/or dimensions of the measurement object are determined from the image. |
