AI Technical Summary
The calibration process of existing 3D scanning devices is characterized by high failure rate, low efficiency, low accuracy and high difficulty due to manual operation of calibration plates or calibration rods. In addition, it requires shooting from multiple angles and positions, and manual adjustment of angles is cumbersome.
A semi-automatic calibration device is adopted, which uses a calibration tripod to support the calibration component and combines it with a gimbal unit to drive the 3D scanner to rotate, so as to realize multi-angle automatic shooting. Multiple calibration points are set on the calibration component to reduce manual hand operation, and the shooting angle is automatically adjusted by computer.
It reduced the calibration error rate, improved calibration efficiency and accuracy, reduced operational difficulty, and shortened calibration time.
