摘 要: 详细阐述了二维光学测量的原理,指出了传统单三角测量中像点位移和表面起伏的关系的不准确性,推导了光学测量头各器件之间的精确关系,给出了测量范围和像点的关系。 This paper describes a theory of 2-d optical mesurement in detail points out the ap-proximaty of the relation between surface undulation and image of light spot,derives accurate relations of all components in triangle measuring device and gives out the relation between measuring range ang the image of light spot. At last, the possibility and the method for the ajust the device is illustrated accarding.
