Paper Abstract

In order to solve the contradiction between wide scope and high precision of coordinate measurement, a new coordinate measurement method based on coding target and vision measurement is proposed. According to the holographic characteristic of coding target, the position and orientation information of coding target can be obtained by any section of coding image on the target, then the position of the target probe can be obtained and coordinate measurement is realized. Two CCD cameras gather target coding image from two right-angled orientations and measurement model is established according to the spatial geometric relation. Special coding target is designed and the parameters acquisition method of coding target is studied. Experiments testify the coding target is designed rationally, and the coordinate measurement method based on coding target is established credibly. The system enlarges the measurement range with the measurement accuracy satisfied.
