Abstract

A new method of guideless coordinate measurement technology based on coding target and vision measurement is proposed. Holographic characteristics of numeric coding target are adopted to obtain target pose and target probe position by any section of bar code on the coding target. 3D coordinates of measuring points can be obtained by coordinate transform. The contradiction between high resolution and large visual field of image sensor is resolved. The measurement system is mainly composed of a coding target, CCD cameras and assistant measuring cell. Analytic model is established according to the spatial geometric relation. A new method and system model for large objects measurement accurately is gained in the field of guideless coordinate measurement. Theoretical analysis and essential experiment prove that the method and system structure is characterized by simple structure and wide measurement range and it can be used in coordinate measurement.
