Embodiment 1

[0039] Such as figure 1 As shown, this embodiment provides a cable pitch detection method, including the following:

[0040] Step 1.1, obtain the image of the cable to be tested as the image to be tested;

[0041] Step 1.2. Measure and calculate the length L of the X-section single-section cable at the cable position of the image to be tested along the cable direction, as follows:

[0042] Step 1.21, build a standard measurement model, including the measurement line along the cable direction and the section line perpendicular to the measurement line and at a certain standard distance from each other, pre-set the length of the measurement line, the width of the section line and the section line of the standard measurement model The standard distance between them forms a standard measurement model;

[0043] Step 1.22, calibrate the standard measurement model at the cable position of the image to be tested to form a measurement area;

[0044] 1.23. Acquire the gray value of th...

Embodiment 2

[0058] Such as Figure 9 As shown, this embodiment provides a method for online detection of cable pitch based on machine vision, including the following:

[0059] Step 2.1, load the configuration data (including the production parameters and measurement model parameters described later and other related production equipment and data designed by the testing process), and start testing;

[0060] Step 2.2, start the visual system including camera equipment and light source;

[0061] Step 2.3, obtaining the image of the cable to be tested as the image to be tested;

[0062] Step 2.4, calculate the pitch of the cable according to the image to be tested, and save the pitch data;

[0063]Step 2.5. Determine whether the pitch meets the requirements. When the pitch is within the error range of the preset value, return to step 2.3 and repeat the operation from step 2.3 to step 2.5. When the pitch exceeds the error range of the preset value, an alarm for adjusting production parameter...

Abstract

The invention relates to a cable pitch online detection method based on machine vision. The cable pitch online detection method based on the machine vision comprises the following steps that configuration data is loaded to start detection; a visual system including photographed equipment and light source is started; an image of a cable to be detected is obtained to be used as the image to be detected; a pitch of the cable is calculated according to the image to be detected, pitch data is stored; whether the pitch meets the requirement or not is judged; and the pitch and the configuration dataare uploaded to a management center. The image of the cable to be detected is obtained according to the visual system, the length L of an X-section single joint cable is obtained by demarcating a measuring line, then the cable core number N is combined to calculate the pitch of the cable to obtain the pitch data, then the pitch data is uploaded to the management center, and the purpose of online detection is achieved.

Description

technical field [0001] The invention relates to the technical field of quality inspection in the cable industry, in particular to an online inspection method for cable pitch based on machine vision. Background technique [0002] In the cable industry, the pitch in the stranding process (also known as twist pitch) is an important indicator that affects cable performance indicators and enterprise cost accounting. Pitch usually refers to the distance along the direction of the cable that a single cable on a twisted wire is wound around the center. The smaller the pitch, the tighter the winding of the cable, and vice versa. The pitch has a direct impact on the softness, toughness, resistance, electrical performance attenuation and other indicators of the stranded wire. There are also relevant specifications for such parameters in the relevant national conductor standards. [0003] For twisted cables with specific manufacturing process and specific application requirements, the...
