Enhanced analysis for image-based serpentine belt wear evaluation

Abstract

Systems and methods are provided for the improvement of an image of a device under test, such as a belt. The image of device under test is made more optimal by determining if the object is rotated away from a preferred axis of the image frame. If so, the image is rotated an opposing angle such that the object is parallel to the preferred axis of the image frame. The rotated image is then made available for analysis of the object. Rib width analysis is performed along the entire length of the detected rib by either de-rotating the image or not.

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 61 / 776,600, filed March 11, 2013, the entire disclosure of which is hereby incorporated by reference. technical field [0003] The present disclosure is directed generally to measuring belt wear, and more specifically to utilizing images to identify belt wear characteristics and predict belt life. Background technique [0004] Serpentine belts are becoming increasingly durable due to the use of ethylene propylene diene monomer (EPDM) material. Thus, historically reliable indications of belt wear, cracking, occur less frequently, but the belt still wears down over time. One problem with the use of these advanced materials is that pre-failure wear detection is becoming increasingly difficult to quantify. In other words, serpentine drive belts made of EPDM material are usually only diagnosed as excessively worn after complete failure of the belt. [...
