| 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 in- terval 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 ana- log measuring instruments,it could reduce cos... |
