AI Technical Summary
Traditional relay locators are easily affected by the complex features of the object being measured when making measurements over a large scale, resulting in incomplete scanning and unstable coordinate transformation relationships, which affects measurement accuracy.
A transfer locator with a spherical support frame structure was designed, equipped with an encoding disk and a small encoding point disk. The coordinate system of the transfer locator was constructed by a two-step calibration method. The three-dimensional coordinates of the encoding points were determined by multi-view feature matching and mean fusion strategies. Accurate calibration was achieved by multi-view beam adjustment optimization.
Ensuring stable identification and tracking by the relay locator at any measurement angle improves the integrity and accuracy of the measurement, achieving stability and precision in global measurement.
