摘要
本系统主要实现了目标物体到两摄像头之间距离的测量,采用ARM嵌入式平台和两个CMOS图像传感器,以Linux为操作系统,用C语言编程实现了对目标物体信息的抓取、显示、处理及测距计算。传统测距方法如超声、红外、激光等有容易受干扰、目标确定困难等缺点。与以前类似功能系统相比,本系统应用立体视觉模拟人眼功能,具有探测范围宽、目标信息完整等优势。最终,在ARM(S3C2410)平台上实现了全部工作,因此,本系统具有便携、快捷等特点,可广泛运用到视频监控、模式识别、汽车电子等领域。
This system mainly achieves the measurement of distance from an object to the cameras, including image snatching, showing and processing of the object and the calculating of measurement based on embedded platform with two CMOS image sensors, the software part of the whole system fulfills with C language under linux environment. Traditional methods of distance-measurement like supersonic or infrared ray have the disadvantages such as ease to be disturbed and difficult to establish the target. While this system can be used to apply stereo vision to simulate human eyes, so it has wide sight area and the ability to get information integrally. Finally, all the work is achieved on ARM （S3C2410）. Consequently, it can be used in many fields, such as video monitoring, pattern recognizing , automotive electronics etc, by advantage of its portability and good performance in CMOS image data processing.
