Abstract
By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News-A new study on Robotics is now available. Accordi ng to news reporting originating in Jinan, People's Republic of China, by NewsRx journalists, research stated, "Because of many advantages, such as single-sided riveting and no welding, blind rivet nuts are widely used to fasten various met al sheets and pipes. However, fixing the blind rivet nut to the base material is mainly accomplished by manual riveting and robot riveting based on teaching-pla yback." Financial supporters for this research include National Key R&D Pro gram of China, Shandong Provincial Key Research and Development Program, Taishan Industry Leading Talent Project. The news reporters obtained a quote from the research from Shandong University, "In order to realize automatic riveting without teaching, this paper proposes a robot automatic riveting method based on machine vision. Firstly, with the help of the light source that increases the difference between the foreground and the background, a binarization method based on morphology is designed to remove lot s of useless information in the image. Then, an improved EDCircles algorithm bas ed on the geometric properties of circular arcs proposed to detect circles in th e binary image, which also realizes the detection of the head circles of the nut . Finally, in order to obtain the precise position of the nut, an optimization m ethod for the inner circle of the nut is designed."
