Stereo Vision Camera

스테레오 비전 카메라 : 두개이상의 이미지 센서가 있어 깊이를 인식할수 있는 카메라 

 

 

 

 

 

Passive techniques

• Depth from focus
• Light field
• Stereo

장점

• Performs well in sunlight
• Cost Effective

단점

• Mediocre performance in low light
• Mediocre performance in non-textured scenes

 

 

 

 

 Active techniques 

• Time-of-flight
• Structured light
• Interferometry
• Stere

 

장점:

• Performs well in low light.
• Performs well in the non-textured indoor scene.
• Can be used as a hybrid Time of flight and Stereo Triangulation depth-perceiving technology.

단점:

• Under sunlight, it is same as passive stereo.
• Over long-range, it is same as passive stereo.
• IR projector adds to cost.

 

 

 

 

 

스테레오 비전 카메라에서 깊이를 결정하는 속성

• Baseline
• Resolution   (해상도는 깊이에 정비례)
• Focal length    (초점거리는 깊이에 정비례)
