摘　　要：为满足内窥场景下立体成像的需求,本研究依据内窥镜系统的构成设计提出一种快速可实现、灵活可扩展的多板协同的多通道图像采集多线程图像处理方案,可基于已有的单通道图像处理电路板,实现多通道相机的同步触发和影像采集。根据所提方案搭建一套双通道图像采集双图线程图像处理电子内窥镜系统,并与常规方案中设计的双通道图像采集单块图像处理电子内窥处理系统进行对比分析。搭建的立体电子内窥镜系统可以实现立体成像,图片分辨率固定为800×800像素,深度测量平均误差小于5%。基于所提设计方案搭建的双通道立体内窥镜立体成像效果显著、研发周期短、研发成本低、灵活性强,表明该方案可以实现并且可拓展到其他多通道系统,比如多通道不同焦距相机等。To meet the requirements of stereoscopic endoscopic imaging,a fast,achievable,and flexible multi-board collaborative multi-channel image acquisition and multi-thread image processing scheme is proposed based on the composition design of the endoscope system.It enables synchronous triggering and image acquisition of multiple-channel cameras using existing single-channel image processing circuit boards.A dual-channel image acquisition and dual-thread image processing electronic endoscope system is built according to the proposed scheme and compared with the conventional scheme which designs a dual-channel image acquisition single-thread image processing electronic endoscope system.The built electronic endoscope system can achieve stereoscopic imaging for a fixed image resolution of 800×800 pixels with an average depth measurement error less than 5%.The dual-channel stereoscopic endoscope imaging system constructed based on the proposed scheme demonstrates high stereoscopic imaging quality,short development cycles,low development costs,and high flexibility,indicating its feasibility and scalability to other multi-channel systems,such as multi-channel cameras with different focal lengths.
