专利汇可以提供Picture processing system专利检索,专利查询,专利分析的服务。并且PURPOSE: To attain the high speed of the calculation and correction of a deviation among pictures by superposing the first template and the objective picture by shifting vertically and horizontally in parallel in order to successively evaluate a similarity, calculating the candidate point of a position whose similarity is high, and shifting the second template to the direction of rotation in order to evaluate the similarity to the objective picture.
CONSTITUTION: A reference picture which has a gradation inputted from a camera is temporarily stored in a reference picture memory 1, the contour part is extracted by an contour extracting part 2, and an untouched contour point string is registered in a second template preparing part 3. Similarly, the point string extracted by the extracting part 2 is transmitted to a first template preparing part 4, stored, the objective picture inputted from the camera is stored in an objective picture memory 5, the contour part is extracted by a contour extracting part 6, and defined as an objective contour picture. Then, the first template is superposed on the objective contour picture prepared by the extracting part 6 after adding an appropriate position offset value to the objective contour picture, the similarity is calculated by a similarity evaluating part 7, and the value is stored in the position corresponding to a three- dimensional score map 8.
