Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stack transfer is performed to achieve complete measurement when obstructed, then measurement completeness is improved, but cost and time increase while precision cannot be ensured
Solution Approach 1:
The patent dynamically switches between tracking scanning mode and stitched scanning mode based on real-time obstruction detection. When the tracker detects obstruction of the scanning head, the system automatically transitions to stitched scanning mode, and when obstruction is cleared, it returns to tracking scanning mode. This dynamic adaptation eliminates the need for time-consuming stack transfers while maintaining measurement completeness.
Solution Approach 2:
The patent introduces a coordinate conversion mechanism as an intermediary that transforms stitched scanning data into tracker scanning coordinate system. This conversion process enables the integration of data from different scanning modes without requiring physical repositioning (stack transfer), thereby maintaining measurement completeness while reducing time loss.
2Reliability
If stack transfer is performed to achieve complete measurement when obstructed, then measurement completeness is improved, but cost increases
Solution Approach 1:
The patent makes the scanning system multi-functional by implementing both tracking scanning and stitched scanning modes within the same system. The stitching module and coordinate conversion mechanisms enable the system to perform both traditional tracking scanning and obstruction-resistant stitched scanning, eliminating the need for additional specialized equipment for stack transfer operations.
3Reliability
If stack transfer is performed to achieve complete measurement when obstructed, then measurement completeness is improved, but scanning precision cannot be ensured
Solution Approach 1:
The patent introduces a coordinate conversion mechanism as an intermediary that transforms stitched scanning data into tracker scanning coordinate system. This conversion process enables the integration of data from different scanning modes without requiring physical repositioning (stack transfer), thereby maintaining measurement completeness while reducing time loss.
Solution Approach 2:
The tracker continuously detects whether the scanning head is obstructed and provides feedback to control the switching between scanning modes. This real-time feedback mechanism ensures that the system maintains optimal scanning precision by using tracking scanning when possible and only switching to stitched scanning when necessary, rather than relying on less precise stack transfer operations.
4Productivity
If tracking scanning mode is used continuously, then scanning efficiency is maintained, but measurement completeness fails when obstructed
Solution Approach 1:
The patent dynamically switches between tracking scanning mode and stitched scanning mode based on real-time obstruction detection. When the tracker detects obstruction of the scanning head, the system automatically transitions to stitched scanning mode, and when obstruction is cleared, it returns to tracking scanning mode. This dynamic adaptation eliminates the need for time-consuming stack transfers while maintaining measurement completeness.
Solution Approach 2:
The patent enables continuous scanning operation by seamlessly switching between tracking scanning and stitched scanning modes without interrupting the scanning process. The real-time obstruction detection and automatic mode switching ensure that scanning action continues uninterrupted, maintaining high productivity while ensuring measurement completeness even during obstructions.

AI summary
Embodiments of the disclosure relate to a method and apparatus for scanning processing, a device, and a medium. The method includes: inspecting state information of a scanning head in real time in a process of tracking and scanning a target object, and acquiring first tracker scanning measurement data based on the scanning head; performing a switch to a stitched scanning mode in a case that the state information of the scanning head satisfies a preset mode switching condition, and acquiring stitched scanning measurement data based on the scanning head in the stitched scanning mode; continuing to inspect state information of the scanning head in real time, and converting the stitched scanning measurement data into second tracker scanning measurement data in a case that the state information of the scanning head satisfies a preset data conversion condition; and obtaining target tracker scanning measurement data of the target object based on the first tracker scanning measurement data and the second tracker scanning measurement data. With the above technical solution, complete measurement of an object to be measured can be achieved without stack transfer in the presence of obstructions in the process of tracking and scanning. Thus, a cost is saved on and scanning processing efficiency is improved while scanning measurement precision is ensured.
