qeasuwing device and corresponding measuring method for three
dimensional attitudengles(yawy
pitch and roll) were designed based on an autocollimator and a
coordinate rotarytrapsArmatrix.
The working principle and structural composition were introduced.
A three-dimensjonalNit&de angle measuring model was established and the theory algorithm by coordinaterotatidpRiatrix
ras derived based on the principle of autocollimation angle measurement.
Then, the ptical ystm was designed according to the demand of the measurement system, A single Field Prograkpming Gte Array(FPGA) was used to implement double CMOS image sensor imaging,
