摘要:
针对小尺寸内花键轮廓特征检测难度大、效率低的问题,开展基于视觉的轮廓特征识别与尺寸测量方法研究。以花键套筒为研究对象,从矩形内花键几何特征分析入手,建立轮廓特征识别与视觉测量分析机制,提出了基于标志特征识别的图像自主找正与轮廓信息提取策略;设计了视觉测量行为分层分析流程。通过实验分析了图像采集、预处理和特征提取3 环节的行为变化对内花键几何参数测量的影响,并实现行为优选。实验结果表明,优选方案对槽宽的测量误差可控制在6.3 μm 以内,外径测量误差在20 μm 左右,内径测量误差在3 μm 以内,单个被测量平均测量用时不高于320 ms,具有较高的测量精度和效率。
Abstract:
Aiming at the difficulty and low efficiency of contour feature detection for small-sized internal spline, the vision-based method for recognizing and measuring geometric contour feature was carried out. Starting from the analysis of the geometric characteristics for the rectangular inner spline by taking the spline sleeve as the research object, the contour feature recognition and visual measurement analysis mechanism was established. And then, a new strategy of image self-alignment and contour information extraction based on the recognition of key features was proposed. After designing the hierarchical analysis process of visual measurement behavior, the influence of behavior changes in image acquisition, preprocessing and feature extraction on the measurement of internal spline geometric parameters was analyzed through experiments, and the behavior optimization was realized. Results show that the measurement error for the keyway width can be controlled within 6.3 μm. Meanwhile, the measurement error for the outer diameter is about 20μm and that for the inner diameter is within 3μm. The average measurement time of a single measurement is no more than 320ms, which has high accuracy and efficiency.
