PROBLEM TO BE SOLVED: To obtain a three-dimensional position posture sensing device capable of stably estimating the three-dimensional position posture of an object without being affected by shield and the like. SOLUTION: A three-dimensional position posture sensing device has an image input means for inputting an image 5 taken by an image device and of which three dimensional position information for a measuring object 1 is known and at least three markers 2 are imaged, a region extraction means extracting the region corresponding to each marker 2 on the image 5, a marker identifying means identifying individual means from the characteristic of outline of the marker 2 in the extracted region, and a position posture operation means operating the three dimensional position posture of the measuring object for the imaging device by using the position on the image 5 of each identified marker 2 and the three dimensional position posture of the measuring object of each marker 2. |
