摘要: 指针式仪表由于结构简单,性能相对稳定,且使用方便、成本低廉,长期以来一直在电厂的水气系统中有着广泛的应用。本文提出一种新的基于图像渲染的仪表指针视频识别方法。其基本思想是利用先进的渲染技术得到“逼真”的合成图像,当给出一幅观测图像时,可以直接改变模型的状态,渲染出合成图像与观测图像进行比较,根据结果不断调整修正模型参数直至合成图像与观测图像间的距离最小,将此作为仪表指针识别的结果。

Abstract: As the analog measuring instrument is easy to use, cost low, performance is stable and its structure is simple, it has been used for a long time in power plant’s water and gas systems. This paper presents a rendering-based video identification method of analog measuring instrument. The basic idea is using synthetic image which is generated by rendering technology to approach the observation image. When the distance between the synthetic image and the observation image is the shortest, the model is made as the result of identification.

Key words: pointer instrument, rendering, model, evaluation function
