Method for the automatic or semiautomatic distance measurement and focusing of the image of an object onto a focal plane

摘要

In the exemplary embodiments, two line-shaped images of a scene are imaged onto two line sensors. The output signals of these line sensors are digitally further processed, whereby the distance measurement ensues by means of sequential examination of the correlation of the digitalized measuring results of the line sensors. For the correlation examination, the parts of the line sensors respectively lying opposite one another and overlapping are employed. The circuit arrangement for implementing this method is contained on one chip in MOS digital technology.
