基于DirectShow的多镜头图像采集系统的设计与实现

实际工程应用中经常要对大面积的图片或物体进行图像采集,传统的图像采集方式在处理这样的实际问题中存在诸多的局限性.本文提出了一种基于DirectShow的多镜头视频采集系统,充分利用了DirectShow"硬件设备无关性"的特点,采用组件对象模型(COM)的系统架构.在实际应用中使用多个USB2.0摄像头作为图像采集设备,可采用顺次或同时的采集方式.系统功能主要由软件实现,极大地节省了硬件的成本.实践表明,该系统在实际应用中能够取得较为满意的效果.

Design and implementation of multi-camera image capture system based on DirectShow

In the practical project application,there is the demand for capturing a large area of images or objects.The traditional images capture style,however,has many limitations of dealing with such real problems.In this paper,a kind of multi-camera image capture system is proposed,which takes the advantage of DirectShow's character of "Hardware equipment Irrelevance",and adopts the system frame of "COM".In the practical application,many USB2.0 cameras can be used as the capture equipments,and the camera can capture pictures in order or isochronously.In fact,the function of this system is mainly made up by software,so that the cost of hardware will be greatly reduced.Through practice,this system has achieved a satisfying effect in the practical application.
