ABSTRACT:
The present invention is intended to measure a three-dimensional position of a tracking object snapped by a camera. The invention is based upon a measuring device using an image provided with an image data input part for inputting an image of a tracking object snapped by a camera and a tracking part for calculating a position of the tracking object and the tracking part moves a frame for extracting image data based upon the image, extracts image data included in the frame from the image in each moved position, counts the number of pixels having a hue feature based upon the extracted image data, determines the position of the frame in which the counted number of pixels is maximum for every hue feature and calculates the position of the tracking object based upon the determined position of the frame.
