TV UNIT FOR MEASURING COORDINATES OF IMAGES OF SMALL-SIZE OBJECTS Russian patent published in 1994 - IPC

FIELD: communication engineering. SUBSTANCE: TV unit for measuring coordinates of objects TV camera 1, control unit 2, analog-to-digital converter 3, coincidence unit 4, gating pulse former 5, the second store unit 6, memory unit 7, the second dividing unit 8, the third storage unit 9, multiplier 10, the second adder 11, the first dividing unit 12, the first storage unit 13, code storing second unit 14, the first adder 15, code storage first unit 16. Light flux carrying image is projected onto light-sensitive surface of multielement CCD of TV camera 1. During period of direct passage of frame scan the pattern of change packs is formed. When back passage of this scanning the pattern is shifted line by line into section of multielement device memory. This pattern is recorded into output register of multielement device and is taken for output element by element when new frame begins to appear. EFFECT: improved precision of measurement of coordinates. 2 cl, 1 dwg
