Abstract:: 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.
