Abstract

A traceable accuracy test method of multi-instrument cooperative measurement system is studied. Here a precise angle dividing table and a linear guide with a laser interferometer are used as standards to test the cooperative measurement’s external parameters. And the coordinates of common points and uncommon points are tested by the scale bars. This testing method is illustrated with a cooperative measurement system composed of two laser trackers. It is obvious that this method can intuitively test the accuracy of the multi-instrument cooperative measurement’s external parameters and coordinates. This method is not restricted by the measurement principle, the data fusion algorithm and the measurement targets of the cooperative system, and it is suitable for various non-fixed layout cooperative measurement system.
