摘要
Abstract
To improve the reliability of aerospace production and assembly,a coaxiality measurement method based on zoom monocular vision for large barrel frame docking was designed.The coaxiality reference axis was established by identifying the circular features of the frame and the cylinder,and the coaxiality of the cylinder relative to the frame was calculated.Based on improved Canny algorithm,a feature edge extraction method for box and cylinder in complex environment was designed.Gradient descent method was used to calculate the center of reference and calibrate the axis of reference.According to the pose adjustment requirements of the cylinder segment,the coaxiality in vertical and horizontal radial directions of the cylinder was solved by using the coordinate system transformation method,and the coaxiality was converted into the pose adjustment output.A cylinder pose adjustment experiment was conducted to verify the effectiveness and accuracy of the above method.The results show that the measuring accuracy of the designed method is as high as 1.50 mm for a cylinder frame with a diameter of 2 m.关键词
