PURPOSE: A device for measuring a 3D shape of a target object of a counter-gradient is provided to measure the 3D shape of the target object by using reflection images filtered by infrared rays, thereby determining a domain of the target object or matching a plurality of reflective domains rapidly and accurately. CONSTITUTION: A device for measuring a 3D shape of a target object(1) of a counter-gradient comprises laser irradiating units(110,130), image acquisition units(120,140), and a measuring unit(200). The laser irradiating units irradiates infrared lasers on the target object. The image acquisition units include infrared filters(123,143) and cameras(121,141). The infrared filter filters only the infrared lasers reflected by the target object. The cameras acquire reflection images of the target object infrared-filtered by the infrared filter. The measuring unit measures the 3D shape of the target object by using the acquired reflection images. |
