Detection algorithm for concentric circles of transparent pipe fittings

Abstract

The invention relates to the technical field of concentric circle detection, in particular to a detection algorithm for concentric circles of transparent pipe fittings. According to the detection algorithm, a controller, a visual detecting device, an X-direction driving device and a Y-direction driving device are included. A calculation method includes the first step of collecting, by the visual detecting device, data information of a measured pipe fitting, and transmitting the data information to the controller for processing; the second step of calculating circular parameters of an outer circle and an inner circle of the measured pipe fitting; the third step of calculating the offset of the outer circle center and the inner circle center of the measured pipe fitting in the X-direction; the fourth step of rotating the measured pipe fitting through 90 degrees in the Z-direction, and calculating the offset of the outer circle center and the inner circle center of the measured pipe fitting in the Y-direction; the fifth step of calculating the outer diameter of the measured pipe fitting, the inner diameter of the measured pipe fitting and the concentricity of the measured pipe fitting; and the sixth step of calculating the thickness of the measured pipe fitting. By the adoption of the calculation method for detecting the concentric circle of the pipe fitting, the inner diameter, the outer diameter and the concentricity of the pipe fitting can be detected, the thickness of the pipe fitting at the random position can also be detected, and the detection precision is high.

technical field [0001] The invention relates to the technical field of concentric circle detection, in particular to a detection algorithm for concentric circles of transparent pipe fittings. Background technique [0002] With the continuous development of science and technology, automatic detection equipment of concentric circles has been widely used, gradually replacing the original manual inspection with naked eyes. The current detection algorithm for concentric circles of pipe fittings is unreliable, leading to the introduction of unsafe factors, which not only fail to solve the problem, but will promote the escalation of contradictory problems. The current detection algorithm for concentric circles of pipe fittings cannot perform accurate detection, and the detection accuracy is low. The problematic pipe fittings are used in daily use. Due to the low concentricity and uneven thickness of the pipe fittings, the service life of the pipe fittings is affected, and the stabi...

The current detection algorithm for concentric circles of pipe fittings is unreliable, leading to the introduction of unsafe factors, which not only fail to solve the problem, but will promote the escalation of contradictory problems. The current detection algorithm for concentric circles of pipe fittings cannot perform accurate detection, and the detection accuracy is low. The problematic pipe fittings are used in daily use. Due to the low concentricity and uneven thickness of the pipe fittings, the service life of the pipe fittings is affected, and the stability is poor, resulting in the exposure of the liquid in the pipe fittings, resulting in waste of resources, and may also affect the surrounding environment.
