| 摘 要： | 对常用的指针式仪表提出了一种新的识别方法，利用标度间隔，分度长与刻度值间的对应关系，识别指针读数，可对线性刻度和非线性刻度的仪表指针“读取”数值。系统采用嵌入式系统设计方案，使用嵌入式Linux为操作系统Qt／Embedded为用户界面开发环境。USB摄像头实时采集表盘图像，初步建立了软、硬件指针仪表图像识别系统，有利于降低成本，增加便利性。

| Abstract: | This paper bring forward a new recognition by using the corresponding relation of scale division, scale interval and scale value that could recognizing the reading of lienear and nonlinear dials. It brings forward a design based on embedded system for the system, embedded linux as its operating system, and also Qt/Embedded as its GUI tools. And it also uses USB camera to fulfill image data acquisition. Based on embedded linux system for automatic recognition of analog measuring instruments, it could reduce ... |
