14. WHY?
-Non contact survey technique
-Useful deliverables with low costs
-Simple workflow
-Can minimise modelling required
-Variable perspective
-Time efficient
-Reduced chance of misinterpretation
-Accurate
-Reliable

18. BLUE = Photogrammetry
RED = TLS
Max deviation ~6-10mm

24. -Accuracy depends on many factors which aren’t traditionally obvious:
-Lighting
-Camera focus
-Number of pictures and overlap between them
-Any visual interference
-…

25. -Limited sharing and cross compatibility

26. -Meeting BIM standards

27. -Errors
BLUE = Photogrammetry
RED = TLS

28. -Data Capture

29. -Data capture
