Conclusions
• Very sensitive to
image noise à cameras with large depth-per-pixel required
• Sensitive to
limited bandwith of LCD
projectors à special projector devices are usually required
• Only motionless
objects
• High
resolution
• Few patterns
Direct codification
• Lower resolution
than time-multiplexing
• More complex
decoding stage
• Occlusions
problem
• A unique pattern
is required
• Can measure
moving objects
Spatial codification
• Large number of
patterns
• Only motionless
objects
• Highest
resolution
• High
accuracy
• Easy
implementation
