Measuring camera.

摘要

The invention relates to a measuring camera consisting of objective, camera body and semiconductor image transducer with camera electronics, in which, for the purpose of focusing, the semiconductor image transducer is arranged axially displaceably along the optical axis within the camera body and the position of the centre of projection of the objective is retained with respect to the housing-fixed coordinate system of the camera even during focusing. The semiconductor image transducer is carried by a sensor carrier and is displaceable by means of highly accurate guides without lateral play and can be positioned by motor or manually. The semiconductor image transducer is preferably positioned under computer control. The active optical groups of the objective are provided with distinctly more accurate values with respect to their lateral and also axial positions referred to the object/camera interface than in the case of known cameras in which the means for focusing are provided on the objective side. The objective can be constructed as interchangeable objective. This measuring camera achieves a much better measuring accuracy. It can be used, in particular, in industrial image processing.
