The invention provides a system for measuring cable structural dimension parameters based on machine vision algorithms. The system uses an illumination unit to illuminate the cable sample to be measured, a position control unit to control the rotation and jump of the sample, and an optical imaging unit to collect the moving sample to be measured. The image information of the cable sample is transmitted to the data processing unit, and the data processing unit calculates the structural size parameters of the sample according to the received image information. The method uses a sub-pixel edge extraction and fitting algorithm to calculate the diameter parameter of the cable profile, and uses a matching algorithm to calculate The thickness parameter of the cable profile, using the area filling method to calculate the number of conductor cores of the cable. The system and method can accurately, quickly and comprehensively measure the structural dimension parameters of the cable, and the maximum thickness of the tested cable sample can reach 10cm, which greatly reduces the measurement time of the structural dimension parameters of the cable and improves the measurement efficiency of the structural dimension parameters of the cable. The measurement procedure is saved and the labor intensity is reduced.
Description
technical field [0001] The present invention relates to the field of cable parameter measurement, and more particularly, relates to a system for measuring cable structural dimension parameters based on machine vision algorithms. Background technique [0002] The measurement of cable structural dimension parameters is a necessary inspection item for cable arrival inspection and random inspection, and it is also one of the most basic test items for discovering cable manufacturing quality defects. Carrying out the measurement of cable structure and dimension parameters is easy to find defects in cable manufacturing quality, which can effectively improve the quality of network cables and ensure long-term safe operation of cables. The measurement parameters of the cable structure size mainly include: the cable structure profile diameter parameter, the cable structure thickness parameter and the number of cable metal conductor cores. At present, when measuring the structural size...
