A field experience:Problems and Solutions


Problem: Turntable- Unable to buy- Expensive

(5,000 USD)

49



Solution:Do it by self

50



Problem:Different exposure in different frame

Solution:Control both of camera aperture and shutter speed

51



Problem:- narrow depth of field- missing focus

Solution:- use a wide angle lens and small aperture- use manual focus

52



Problem: Reflection on the objectSolution: Using a backlit vinyl cover

in front of the lighting lamp.

53



Problem: Breaking an objectSolution: - serious personnel training

- code of conduct- attitude

54



Problem:Insufficient computer resources for 3D modeling operation

Solution:Need future upgrade

55



Problem:Long time operation for 3D laser scan (about 3 days for scanning the Buddha and 2 months for post production)

Solution:Need more knowledge, tips and more practice

56



Problem:Take a vertical shot ofPhotographic VR

Solution:Unable to find a good (cheap and high quality) solution

Progress of the projectProgress of the project

• Completed 2 objects by using 3D laser scanning technique

• Completed 35 objects by using photographic VR technique

• Finished design and development of the web-based system including data entry of the above objects

59

Future workFuture work

• Reducing development time for 3D laser scanning technique

• Adding 360 degrees vertical rotation feature for Photographic VR technique

• Improving a virtual room• Developing web-based software for

creating e-museum and information management system
