| 摘要 |
The invention relates to an image processing system, containing an optical digital camera (1) having means (4) that produce information representative of a specified geometric distance within the image using laser light in the detection range of the optical digital camera (1), said information representative of the specified geometric distance being processed together with the image information. Separating means (8) are arranged downstream of the digital camera, said separating means separating the information representative of the specified geometric distance from the image information. Subsequent evaluating means produce a distance value therefrom. Image storage means (9) additionally arranged downstream of the separating means are used to store the recorded image information. Adjustment means (14) automatically change the image size on a display in the form of a digital zoom for the purpose of setting the reproduction size according to a specified scale factor in such a way that an object contained in the image content, the physical dimension of which object corresponds to the specified geometric distance, is reproduced in a corresponding dimension that is multiplied by the specified scale factor. |

1. An image processing system comprising:
an optical camera with a large depth of field, a digital image sensor, a laser light source generating an information representative of a geometric distance in the form of a pattern, which is detected and processed with the image data captured by the camera, image memory means (9) and a monitor (3) for reproducing the captured image data, wherein the camera (1) having a separator (8) downstream connected thereto which separate the information representative of a geometric distance from the rest of the image data, the separator (8), having an evaluator (13) downstream connected thereto which determine and output physical distance data from the information representative for geometric distance, an actuator (14) for varying the size of the reproduced image on the monitor (9) in the manner of a digital zoom, controlled by the geometric distance data as an input variable, for adjusting the size of the image representation on the monitor (3) in accordance with a scale factor, the physical distance data being included as a multiplier, such that an object contained in the picture data having a physical size corresponding to the physical distance data it is reproduced on the monitor in a size, which is defined by the preselected scale factor, wherein means are provided for generating several laser markings arranged around the optical axis of the camera (1) in symmetric positions, and wherein the image processing system further inhibits those laser markings from further processing within the data of the image representation, that are detected in a position differing from the symmetry position with respect to the optical axis of the camera by more than a predetermined amount. |
