Photogrammetric method for determination of the center of optical signal marks on moving objects, e.g. for use in crash-test evaluation, whereby adjoining pixel groups are combined and evaluated to yield fast data compression

摘要

Photogrammetric method for determination of the center of optical signal marks on moving objects that are recorded using a video camera. The electrical image signals from the camera are transmitted as row type sequences of pixels to a digital image- processing device for data compression. Data compression involves combination of an n x m matrix of adjoining pixels for grouped evaluation. An Independent claim is made for a device for photogrammetric measurement comprising a control unit with which pixels are combined to form matrices and then evaluated as control signals before being transmitted to a computer.
