摘　　要：本文论述了二种新型光电近程视觉传感器的工作原理、计算方法和系统构成。一种是由多个点光源和位置敏感器(PSD)构成的传感器,文中从误差分析、统计运算的角度出发推导出确定被测对象空间信息的算法;另一种是由多个点光源和单个探测元件构成的传感器,这种传感器通过对位相信息的测定来感知物体的三维信息。两种传感器都能得到被测点到传感器之间的距离信息及被测表面空间取向的信息。所论及的传感器可用于机器人对三维物表面轮廓的追踪运动以及提供物体形状的三维描述信息等方面。Operating principle, calculating method and system constitutionof two novel photoelectric path vision sensors are described in the paper.One is a detector consisting of multiple point sources and position sens-ors. The calculating method for measured object spatial information is de-rived from the errors analysis and statistical operation. The other detectorconsists of multiple point sources and single detecting element.The detectorsenses 3-D informations of the object through determining the phase info-rmation. Doth detectors can obtain the distance informations between themeasured points and detectors and the information of measured surfacespatial orientation. The described detectors can be applied to the trackingmovement of robot for 3-D surface profile, and describing 3-D informat-ion of object shape.
