Which of the following refers to the process of merging different scans into a complete model?

The process of merging different scans into a complete model is accurately described by the term registration of the scans. Registration involves aligning multiple scans of an area or object in such a way that they can be seamlessly combined to create a coherent and comprehensive representation.

This process is crucial in surveying and modeling, as it allows surveyors to synthesize various datasets, often collected from different angles or times, into a unified 3D model. The registration process typically entails identifying common points or features within the individual scans, ensuring that they are oriented correctly relative to one another.

In contrast, data stitching generally refers to the technique of combining multiple images or data sources but does not specifically denote the alignment and scaling aspects that registration involves. Model integration would encompass a broader range of activities, including assembling and organizing data rather than solely focusing on the alignment of scans. Coordinate transformation refers to changing the coordinate system of the data, which is a step that may be involved in the registration process but does not encompass the entire merging process.
