| Abstract: | The hardware structure and software design of the vision positioning system for IC packaging equipment,taking the auto grinding dicing saw for example.An Image processing algorithm based on Open CV Vision Library is developed to control the movement of the work table,so that the dicing street of the work pieces could be precisely positioned.As to template matching,this algorithm adopts the popular edge geometry matching method,and has achieved acceptable result in the field test of the grinding dicing saw. |
