PURPOSE:To measure a correct position of work, by a method wherein a rough position of work is measured by a stereoscopic processing means through an image from a camera to determine the correct position thereof with a separate distance sensor subsequently. CONSTITUTION:Images taken with cameras 1 and 2 are converted by image processing means 11 and 12 into digital image signals. Distance of a connector (work) 4 is measured by a stereoscopic processing means 13 in a 2-D manner by trigonometry from right and left digital images of the image processing means 11 and 12. Then, the posture of the connector 4 is detected from the digital image data. after the judgement of the posture, the positions of the cameras 1 and 2 and the ultrasonic sensor 3 are changed to a point of the right angle to one surface of the connector 4. Then, an ultrasonic wave 6 is emitted from the ultrasonic sensor 3 to measure distance accurately between the ultrasonic wave sensor 3 and the connector 4.
