摘要
提出了一种基于图像识别技术的螺栓裂缝非接触识别技术。利用高精度工业相机对待检螺栓进行拍摄,然后采用细化、提高曝光度、图像分割等技术对拍摄到的图片进行处理,获取图像特征,最终达到识别裂缝的目的。实验表明,将图像识别技术应用于螺栓裂缝识别领域,可以大大简化识别步骤,提高识别精度,为螺栓裂缝检测提供了新的发展方向。
Propose a non-contact identification of bolt crack based on image recognition technology. Take photo of every bolt waiting for the detection with high-precision industrial cameras, then process the photos with image thinning, improve exposure, edge detection technology, so we can get the image fea- ture, and finally achieve the purpose of crack identification. The experiment shows that the use of image recognition technology in bolt cracks identification can greatly simplify the identification step, improving recognition accuracy, and provides a new direction of development for the bolt cracks detection.
