Embodiment Construction

[0038] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0039] It should be noted that like numerals and letters denote similar items in the following figures, therefore, once an item is defined in one figure, it does not require further definition and explanation in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second" and the like are only used to distinguish descriptions, and cannot be understood as indicating or implying relative importance.

[0040] In the prior art, the specific position of the nozzle on the workpiece is usually determined by using the Hough circle-finding algorithm based on the open source library or the target detection algorithm based on deep learning.

[0041] However, for the Hough circle-finding algorithm, it is only suitable for regular circular objects, and the robustness ...

Abstract

The embodiment of the invention provides a workpiece assembling method, device and system, and the method comprises the steps: obtaining a pipe opening image of a to-be-assembled workpiece, wherein the pipe opening image is an image comprising at least part of a pipe opening region of the to-be-assembled workpiece; extracting contour information of at least part of the pipe opening region from the pipe opening image; carrying out ellipse fitting on the contour information to obtain ellipse parameters of a fitting ellipse; calculating a circle parameter of a circle after fitting ellipse transformation by utilizing the ellipse parameters; and according to the circular parameters, positioning the pipe opening corresponding to at least part of the pipe opening region so that the to-be-assembled workpiece can be assembled conveniently. By means of the technical scheme, compared with an existing workpiece pipe opening positioning method, the calculated amount is greatly reduced, and the real-time performance of pipe opening positioning is guaranteed.

Description

technical field [0001] The present application relates to the field of workpiece assembly, in particular to a workpiece assembly method, device and system. Background technique [0002] In modern manufacturing technology, automated assembly technology can partially replace manual skills and judgment for complex assembly work to improve production efficiency and ensure product quality and stability. In the part assembly process, there are many tubular workpieces to be assembled, so it is necessary to accurately locate the specific position of the nozzle on the workpiece to successfully complete the assembly task. [0003] In the prior art, the positioning method of the nozzle of the workpiece is usually realized by using the Hough circle-finding algorithm based on an open source library. [0004] In the process of realizing the present invention, the inventor found the following problems in the prior art: due to the large amount of calculation of the Hough circle-finding alg...
