摘　　要：针对视频源制式和图像质量的需求不同,提出一种动态配置程序集采集图像的方法。采用接口技术抽象采集接口和程序集的管理接口,通过反射机制选择不同采集卡对应的采集程序集,软件动态绑定到采集卡进行图像采集。在描述采集流程之后,讨论了采集接口和管理接口设计,给出了SDK2000视频卡的具体实现。实验结果表明,增加、改变采集卡后,减少了软件重新发布的工作,增强了软件的可扩展性和可维护性,提高了软件在不同需求环境下的适应能力。Considering the difference of video standard and requirement of quality of images,a method of capturing image by dynamically setting capturing assemblies is presented.Interface program technology is applied to abstract method,inherited by software development kit of video card and the interface management assembly.Video captured by load assembly with reflection dynamically,in turn binding the corresponding video card.After the capture flow is given,the design of capture interface is discussed;the implement assembly of SDK2000 video card is demonstrated.The result show that development and republishing software are eliminated after the video cards are altered,thus the extensibility and maintainability of software is enhanced,and also the portability of software is improved.
