| Abstract: | A vision inspection system for inner surface is introduced based on circle structured light. The image feature of circle structured light for inner surface is analyzed, and the reason for having disturbance light stripes is explained in detail. A method for erasing disturbance light stripe and extracting useful stripe in sub-pixel are presented. Moreover, a method for extracting step image edge is given based on a step edge model, and the model parameters are estimated with non-linear optimization. Experimental result shows that the extracting method is fast, robust and accurate. |
