The probe technique based on non-diffracting beam is proposed to be combined with a total station or a laser tracker to form a combined measuring system, which realizes the coordinate measurement of hidden parts in large spaces, in large-span measurement environments, space barrier, blocking.Depression of the measured point and other factors make it impossible to optically and directly measure some areas of the measured article. A attitude measurement probe prototype based on non-diffracting beam technology is developed for a system combined with a total station applied in coordinates precision measurement of hidden areas in large-scale space, the uncertainty of spatial location measurement is analyzed, and the measurement comparison experiment is completed. Experimental results and analysis indicate that the precision of probe’s attitude-measuring system and combing measurement system are 1 mrad and ± 1 mm, respectively, demonstrating more flexibility and reliable precision during combined measurement.
