Abstract

PURPOSE:To make it possible to measure the position of an object in a short period of time, by projecting light patterns which are alternately differently coded to the object many times. CONSTITUTION:An image of an object 1 to be measured is, after irradiation with a light pattern 7 from a projecting means 6, formed on a television camera 8 placed at a different position than the projecting means 6. The light pattern projecting means 6 has an illuminant first zone and a non-illuminant second zone alternately provided each other. The first zone and the second zone are selectively changed. Accordingly, the object 1 is irradiated with the light patterns 7 many times which are coded alternately differently from each other. A formed image of the object of each light pattern 7 is divided into many pixels by a processing means 9 to be binary-coded into light and dark. The binary-coded pattern is stored into memories 10 and 11, and read out to calculate the position of the object 1.
