一、概述随着工业自动化生产的日益普及,大规模生产线上的产品质量检测需求越来越使得人工检测方法无法适应。计算机视觉正在成为一种提高生产效率、保证产品质量的关键技术而被日益广泛采用。例如机械零件产品的自动检测及生产流水线的自动测控等都可以采用计算机视觉技术。在一般的应用场合中大多只需要二维的灰度图像就能够满足基本的检测要求,但也有 First, an overview With the increasing popularity of industrial automation, mass production line product quality testing needs more and more artificial detection methods can not adapt. Computer vision is becoming more and more widely used as a key technology to increase productivity and ensure product quality. For example, automatic detection of mechanical parts and automatic production line control and measurement can be used computer vision technology. In most applications, most of them only need two-dimensional grayscale images to meet the basic detection requirements, but there are also
