Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If reference line position is determined during image composition process, then composite image can be generated, but reference line position accuracy deteriorates due to position changes during composition
Solution Approach 1:
The patent calculates the reference line position in advance based on the spatial relationship between original images and composite image before composition operations are applied. By determining the position beforehand and then applying composition transformations to both the image and reference line consistently, the position accuracy is maintained despite the composition process
Solution Approach 2:
The patent employs feedback mechanisms where the reference line position is calculated based on the composition relationship, and this calculated position is used to adjust and refine the final reference line display. The system continuously refines the position information by considering the spatial transformation relationships
2Stability of the object's composition
If reference line position is fixed during composition, then position stability is maintained, but adaptability to different composition operations deteriorates
Solution Approach 1:
The patent makes the reference line dynamic by calculating its position based on the actual composition relationship between original and composite images. The reference line automatically adapts to different composition operations (translation, rotation, scaling) by recomputing its position according to the transformation parameters, thus maintaining both stability through consistent calculation methodology and adaptability through flexible computation
3Ease of operation
If manual adjustment of reference line is allowed, then positioning flexibility is improved, but operation complexity and time consumption increase
Solution Approach 1:
The patent implements self-service by enabling automatic calculation and positioning of the reference line based on the composition relationship between images. The system autonomously determines the reference line position without requiring manual intervention, thus maintaining operational flexibility while significantly reducing time consumption. Users can still make adjustments if needed, but the baseline positioning is handled automatically

AI summary
The present disclosure involves a reference line determination method and system. In a process of determining a reference line, a plurality of original images containing a first spatial position information are obtained. According to the plurality of original images, a composite image containing a second spatial position information is further determined. After a composition relationship between a plurality of original images was determined, a reference line is determined on the composite image according to the spatial position information.
