Bending angle calculation method for joined pipes
The patent US12044524B2 outlines a method and apparatus for calculating the bending angle at the joint of two pipes. The process begins with capturing an image of the joined pipes, followed by deriving a laying direction straight line that corresponds to the pipe's orientation. The method calculates the bending angle by determining the crossing angle between the laying direction straight lines of the first and second pipes. Additionally, it creates a table that correlates the calculated angle from the image with an angle in the depth direction formed by the two pipes. The setup includes a supporting column and a horizontal arm with a camera positioned to focus on the joint area, facilitating accurate image capture.
Further claims detail enhancements to the method, including contour extraction of the pipes to improve the accuracy of the derived laying direction straight lines. Various techniques for deriving these lines are described, such as using contours, center lines, and predefined shapes or patterns on the pipe surfaces. The method also allows for the integration of a derivation assisting tool to aid in the image capture process. Overall, the patent presents a comprehensive approach to accurately measuring the bending angle of pipe joints, which could have significant applications in fields requiring precise pipe alignment and installation.
