A first points range of high brightness and a second points range of high brightness in a photographed image are selected. It is checked if an identical end point is shared by the three and four points range selected. A first straight line, connecting a center of gravity corresponding to the identical end point and a center of gravity corresponding to another end point of the first points range opposite to the identical end point, is calculated. A second straight line, connecting the center of g...

A three points range of high brightness and a four points range of high brightness in a photographed image are selected. It is checked if an identical end point is shared by the three and four points range selected. It is checked if a center of gravity corresponding to the identical end point, a center of gravity corresponding to another end point of the three points rage opposite to the identical end point, and a center of gravity corresponding to another end point of the four points range oppo...

Methods, systems and computer program products are provided for determining an obscured contact point based on a visible portion of an acoustic sensor of a medical device contacting a patient by acquiring a first image containing an upper surface of the acoustic sensor from a first viewpoint and a second image containing the upper surface of the acoustic sensor from a second viewpoint different from the first viewpoint. The acoustic sensor is located in the first image and the second image and t...

The invention relates to a process for the photogrammetic acquisition of a static object to be photographed with the aid of at least one optoelectric solid-state area sensor, of which the image area is smaller than that of the total image aimed at, the point array of a reseau (glass plate having suitable point markings distributed in grid fashion) being included in the photogrammetic imaging system and the area sensor being arranged behind the reseau plane in such a way that in each case it imag...

A device for connecting a stereocomparator to an electronic computer to set up an analytic photogrammetric plotter. In the control device of a stereocomparator, some of the stereoscopic exploring motions of the photograms for the plotting take place with a manual control, and an electronic, digital or analog computer receives information and elaborates the same to obtain additional data relating to at least one other motion. Apparatus is provided to translate said additional data into motion.
