AI Technical Summary
Existing visual measurement methods suffer from a contradiction between measurement accuracy, measurement degrees of freedom, and measurement range in ultra-precision measurement, especially in achieving complete six degrees of freedom and a large measurement space.
A spatial multi-degree-of-freedom pose vision ultra-precision measurement system is adopted, including a main industrial camera, multiple auxiliary industrial cameras, a lens fixing bracket, a marking device, and a precision motion device. Through binocular stereo vision and related algorithms, in-plane measurement under the telecentric lens is extended to achieve six-degree-of-freedom ultra-precision measurement.
It achieves a larger common measurement range and depth of field, and can complete a full six-degree-of-freedom ultra-precision measurement, improving measurement accuracy and degrees of freedom.
