I'he purpose of this paper is t o build a computer vision system that cndows an ant onomous mobile robot the ability of automatic measnring of the anlog and digital meters installed in nuclear power plant (NPP). In the m ~t e r image captured by the camera, the meter area is sorted out using mainly the thresholding and the region labeling. The positions and the angles of the needles in analog meter images are detected using projection based method. In the case of digital meters, digits and
