摘　　要：立体视觉测量的单摄像机结构相对双摄像机结构在结构尺寸、检测速度和经济成本上有明显的优势,有着广泛的应用前景。从原理和结构方面分析了单摄像机立体视觉测量的结构精度。结合双目立体视觉的基础与单摄像机测量结构的具体组成,用数学方法解析各个因素的影响情况,得出较为直观的数学描述;对结构尺寸和精度要求进行综合考虑,针对大视场角结构设计的复杂性,完成结构设计过程,提出较合理的结构形式;通过相应的实验进行精度验证和分析,验证了设计和分析方式合理性。Comparing to dual camera structure, single camera stereo vision measurement has an obvious advantage of structure size, measurement speed and cost, also it has a wide application prospect： The precision of single camera stereo vision measurement based on the principle and structure is analysed. According to the principle of binocular stereo vision and the components of single camera stereo vision, the different factors are discussed and influenced of precision, and get a simple mathematic expression. Considering the structure size and precision request, the structure is designed which aim at the complexity of large visual angle structure. The precision and reasonability of design and analysis are testified by reasonable experiments.
