摘　　要：在传统双目立体视觉传感器的基础上,对基于平面镜成像的单摄像机立体视觉传感器进行了研究。在电荷耦合器件(CCD)摄像机前放置一平面反射镜,通过对目标物体和其虚像进行拍摄,得到一幅具有视差的图像,该图像相当于摄像机和其在平面镜中的虚拟摄像机从不同角度对目标物体进行拍摄,具有双目立体视觉的功能。建立了单摄像机立体视觉传感器数学模型,分析了参数对单摄像机立体视觉传感器的视场范围和测量精度的影响,设计了传感器参数尺寸,进行了相关实验验证。实验结果表明,该测量方案方便有效,结构简单,调节方便,尤其适合近距离高精度测量。A single camera stereo vision sensor based on plane mirror imaging is researched on the basis of traditional binocular stereo vision sensor. Placing a plane mirror in front of charge coupled device （CCD） camera, a picture with parallax image is obtained by shooting target object and its virtual image. This is equivalent to shot the target object from different angles by the camera and the virtual camera in plane mirror, so it has the function of binocular stereo vision. The mathematical model of single camera stereo vision sensor is established. The impact of the parameters to the field range and the measurement accuracy is analyzed. The parameters of the sensor are designed, and the corresponding experiment has been done. The experimental results show that the measuring method is convenient and effective. It also has the advantages of simple structure, convenient adjustment, and is especially suitable for short distance measurement with high precision.
