PURPOSE: A 3D(three-dimensional) position detection device of a moving object and a method thereof are provided to easily and quickly detect the same marker in different images by attaching markers that reflect light with different colors. CONSTITUTION: Several color markers(102) are attached at each part of a moving object(100). The image of the object(100) is input to an image processing and position calculating unit(110) from several cameras(104,106,108). Pixel value of the individual input image is calculated at the image processing and position calculating unit(110). If the pixel value is larger than 100, it is judged to be marker; and otherwise, it is judged to be background. Intensity of red, green and blue is examined for the markers to identify the same markers. After determining the marker position on an image coordinate, the 3D position is determined by stereo matching the same markers.
