摘要	When mechanical arm arrests target, relative pose between target and hand-eye camera of arm is required to be obtained with real-time. By using image coordinate of mark points of cooperative target, P3P algorithm was adopted to realize high precision calculation of relative pose. Firstly, circles and straight lines of cooperative target were rapidly identified and the area of target circles was determined. Secondly, target area was divided into many square windows with mutually overlapping; with the highlight of each window as candidate point, circular feature of mark point was applied to eliminate illegal points by combining with various conditions, while three legal mark points were kept so as to determine center coordinates of the mark point finally. Lastly, combine with dimension information of participated target in camera and obtain relative pose with P3P algorithm. Simulation results show that the accuracy rate of the mark point identification is higher than 99%; rotation error of pose calculation is less than 0.1; translation error is less than 0.5mm. In actual experiment, the above parameters respectively are 97%, 0.2and 1mm. Operation of the algorithm is simple with high speed, high accuracy and high precision, applicable to high accuracy real-time monocular pose measurement of industry, agriculture, aerospace and other fields. 2016, Science Press.
