Other AbstractThe present invention discloses an object model of three-dimensional objects position and a method of position, where precise depth of and attitude information of the three-dimensional objects can be acquired with a rectangular pyramid model position. The four sides and the placement underside of the rectangular pyramid object model is black-and-white. The model contains twelve straight lines and is placed with the square underside rotating at 45 degrees around the axis. Combining with the model, a position algorithm is designed. For any three straight lines intersected at two points (wherein, the distances between the camera focal center and each of the two points are different) on the rectangular pyramid object model, a position mathematics model is established according to the angle information between the straight lines and the length information of the straight lines. For the model, solution is worked out based on geometry combing step acceleration. The present invention has the advantages of easy image processing, strong anti-screening ability, free selection of lines, precise position, simple position algorithm and powerful real-time performance.
