A real-time cable pitch extraction method

Abstract

The invention discloses a real-time cable pitch extraction method, which includes a learning and training phase and a real-time detection phase. The learning and training phase includes the following steps: A. Dealing with the following image acquisition environment variables: 1) open environment; 2) image 3) Uneven illumination in the picture collection area; 4) The cable shakes along the direction perpendicular to the direction of travel. In the present invention, the algorithm is divided into learning and detection phases, and the two phases are carried out step by step. Most of the parameter information required by the algorithm can be obtained through the learning phase. Only one parameter needs to be provided by the outside world, and the parameter can be obtained by directly observing the image without repeated experiments. , the maintainability is very good; the algorithm has a reasonable error distribution, each step has a large error tolerance range for outliers, and has good robustness; at the same time, the efficient implementation of the algorithm reduces the pressure on the hardware platform , the processing efficiency ensures the real-time detection.

Description

technical field [0001] The invention relates to the technical field of visual detection and cable pitch production quality monitoring, in particular to a real-time cable pitch extraction method. Background technique [0002] Cable is a general term for optical cables, cables and other items. There are many uses of cables, mainly used for multiple functions such as control installation, connection equipment, and power transmission. It is a common and indispensable thing in daily life. Because cables are charged, Therefore, the installation needs to be particularly cautious. The winding machine is mainly used to form multiple cables. It is widely used in power cables, communication optical cables and various low-voltage synthetic wires. The cable pitch is Refers to the length of the helix formed when the single wires are wound with each other. The pitch of the winding equipment for the cable is mostly controlled by the speed of the wire. [0003] The strand pitch affects the ...
