Abstract
PURPOSE: To detect the positions of center of gravity of plural objects with a video rate, by accumulating the coordinate and the number of image elements of a significant image element at every partial area for an input image, and calculating the centroid position from an added value at every label of the partial area.
CONSTITUTION: The video signals of the objects 2 and 3 from a TV camera 1 are inputted to a processor via a synchronizing separator circuit 4 and a binarization circuit 5. And an S counter 7 counts the number of significant image elements of input binary information, and a Y counter 8 identifies a Y-axis coordinate at a prescribed point, and an X counter 9 identifies an X-axis coordinate, respectively, and each coordinate is added cumulatively at full adders 12 and 16, and respective count value is stored in a memory device 25 via a full adder 20. Based on the above stored value, a CPU 26 attaches the label which separates the partial area linked or non- linked mutually in the partial area where the area of the significant image element exceeds a prescribed value on the partial area, and calculates the centroid positions of the objects 2 and 3 at every set of a linked partial area by the label by using an accumulated coordinate value.
