摘　　要：在充分研究立体相机参数设置准则基础上,提出了一种立体相机微距拍摄质量的客观评价方法.结合平行和会聚相机不同的内部结构及成像规则,分别研究两种立体相机的内部参数和场景参数对拍摄质量的影响,通过大量主观实验,最终建立了立体相机微距拍摄质量客观评价模型.实验结果表明,所提出的评价模型与主观评价结果基本一致,能够反映立体相机微距拍摄质量的优劣.Through analyzing the parameter setting rules of stereo cameras, an objective macro slaootmg quality evaluation method of stereo cameras was proposed in this paper. Combining the different internal structure and image- forming rules between parallel and toed-in camera configurations, the influence of camera inner parameters and scene parameters on stereo cameras shooting quality was researched respectively. Then according to the subjective assessment, the objective macro shooting quality evaluation criteria for stereo cameras were built. The experimental results show that the proposed evaluation method is basically in accordance with subjective evaluation and can reflect the stereo cameras＇ macro shooting quality.
